Last month the Kirkland, WA based Bluetooth Special Interest Group (SIG), the organization that
oversees Bluetooth wireless communication protocols, agreed to and published a set of specifications
that created a standard that will allow us to integrate smart lighting controls to cover large areas - even
when we mix products from different lighting manufacturers. An article, published a couple of weeks
ago, titled, “Bluetooth’s range just widened, and IoT lighting companies are thrilled”, published on July
18, 2017, by Mark Halper, Contributing Editor, LEDs Magazine, and Business/Energy/Technology
Journalist, opened our eyes to just how important this agreement may be to future LED lighting
“After at least two years of internal wrangling and difficult technology choices, the Kirkland, WA-based
Bluetooth Special Interest Group (SIG) ratified a means to mesh together Bluetooth beacons, allowing
them to hand off instructions to each other. The move effectively boosts Bluetooth's reach far beyond
the 30 feet that is typical for the Bluetooth that consumers commonly use to share things like audio files
among smartphone, computers, tables, TVs, and other devices.
“We just completed a several-year effort of completing a set of specifications that define a standardized
approach for creating true industrial-grade mesh networking solutions using Bluetooth technology,”
Bluetooth SIG vice president of marketing Ken Kolderup said in a phone interview with LEDs Magazine.
“Now there's a standard way that defines how mesh networking gets done on Bluetooth, so that all
the vendors can now create interoperable solutions.”
Now that, potentially, clears a lot of road blocks, especially for organizations, like retail stores,
warehouses and commercial offices, that choose to upgrade their lighting to LED over the course of time
and prefer to control them all from a single point or device. “There was some real work to do; it's very
demanding, especially for a commercial environment,” said Bluetooth SIG's Kolderup, who noted that it
took time to work out details related to reliability, scalability, performance, latency, security, and other
aspects. The SIG also performed extensive interoperability testing to assure the best chance of all
Bluetooth devices — the SIG has 32,000 members — working together in any scenario. For example,
“We need to make sure that a switch you buy today can work with a light bulb you buy from a vendor
that may not even exist today, 20 years from now,” he noted.
Now that is truly working together to accomplish a goal that will benefit us all. For more information, or

As we become more familiar with the latest evolutionary (some may even say revolutionary) lighting
options, for both commercial and residential lighting, namely, LED Lighting, we have begun to hear more
and more about smart lighting controls. The beauty of smart lighting controls is that you are able to
integrate wireless controls either directly onto your fixture or in-line at the point of power input of the
fixture. You can then preset or manually adjust dimming levels, conserve energy through daylight
harvesting and/or make use of occupancy sensors to meet your specific application goals. There are
several platforms out there today that require a hardware device, like a gateway or hub, to
communicate with your wireless LED lighting fixture controls, but, lately there has been a push to
develop a way to accomplish this right from your smart phone or mobile device. It looks like that goal is
on the way to being accomplished.
From an article titled, “Vendors roll out compliant Bluetooth Mesh enablers for solid-state lighting
products”, Published on July 26, 2017, By Maury Wright, Editor in Chief, LEDs Magazine, I read the
“…the Bluetooth Special Interest Group (SIG) delivered the long-anticipated Bluetooth Mesh standard
last week formalizing support for mesh-based networks, including lighting-centric applications that
combine LEDs and connectivity. Now companies that deliver ICs and/or Bluetooth software stacks that
can accelerate solid-state lighting (SSL) product development are offering Bluetooth Mesh-compliant
building blocks — Qualcomm, Silvair, and Silicon Labs are among the first to announce such enabling
technologies. Those products may be critical in the acceleration of SSL as a part of the Internet of Things
Bluetooth Mesh has been long anticipated because the new mesh technology will still interoperate with
the Bluetooth links in our smart devices allowing connections with LED-based lighting products without
the need for a gateway such as would be required with ZigBee-based products and most other wireless
schemes. Bluetooth has lacked the range to serve in even a robust residential SSL installation or even
the simplest commercial implementation, but the mesh capability extends the range by passing
messages from node to node…
“We expect to see a wave of new devices hit the market quickly by leveraging ubiquitous Bluetooth
connectivity to create hub-less mesh networks that extend the range and reliability of Bluetooth
systems,” said Daniel Cooley, senior vice president and general manager of IoT products at Silicon Labs.”

As of Sept. 1, lighting manufacturers are now required to submit all applicable products under a new set of DLC requirement updates which will go into effect for consumers on Jan. 1, 2017. Now, I don’t pretend to think that all of you reading this article know what DLC stands for and why it exists, but it will have an impact on the lighting you purchase. Let’s break that down before we dive into how these changes may impact your lighting.
What is DLC?“DLC” stands for “Design Lights Consortium” (oh you knew that did you?) and, according to their website, the designation “is dedicated to accelerating the widespread adoption of high-performing, energy efficient commercial lighting solutions. In collaboration with industry stakeholders, DLC defines high performance through technical requirements, facilitates thought leadership, and provides tools, resources, and technical expertise to members and industry.”
In layman’s terms, that means that DLC is a rating system that identifies through testing and manufacturer data which lighting products are generally regarded as being acceptable for their intended use.
Essentially, DLC is like having a “CarFax” report. That used car may look like it will perform well, but the CarFax shows what it has been through and what to expect. DLC does something similar (they don’t rate cars yet, unfortunately) in regards to lighting.
Here are a few of the categories that DLC looks at:
Conversations began taking place toward the beginning of 2016 by DLC stakeholders about establishing a “DLC Premium” category and a “DLC Standard” category that would differentiate products that were qualified for DLC. The reason behind this was to show those products that rose above and beyond the technical requirements and could be viewed as “premium” choice lighting products.
So, what is DLC 4.0?Manufacturers were required, as of Sept. 1, to submit all products for a new, more stringent set of efficacy standards, otherwise known as DLC 4.0. With this new standard, the gap between those standard and premium products will be even greater as DLC calls manufacturers to higher lumen-per-watt, or light output per energy consumption, standards. Just as important, products that no longer meet the DLC 4.0 standards will be de-listed on Apr. 1, 2017.
Here is an outline of the changes and how they may affect your lighting:
1. The primary update to DLC was in regards to the efficacy of all DLC-qualified LED productsLED lighting technology has improved immensely over the last five years, and the attention of the manufacturers has turned toward the efficiency of their drivers and their products’ performance. Efficacy, usually expressed in lumens per watt (LPW), is now a leading parameter for what type of rating will be given to a product, whether Standard or Premium. The more efficient the product, the more lumens (measured light output) you will get out of your wattage.
Let’s take a linear LED troffer as an example. Currently for that product to be DLC Premium, it must achieve 110+ LPW. With the revisions in June 2016 and the new products hitting the QPL in January 2017, the new requirement is 125+ LPW. The reasoning behind this change is to differentiate between the mass amount of product that currently qualifies as DLC.
2. Utility companies are going to follow this revision with their incentive programsOne of the reasons these DLC changes should be paid close attention to is that it will affect the amount of utility rebates you will receive. Utilities need to find unique ways to take energy off the grid, and offer rebate programs to commercial businesses for lowering their electrical load.
We are already seeing certain utility companies offer “tiered” rebate approaches for lighting products involving DLC Standard vs. DLC Premium. Once the QPL is published in January 2017, delineating between DLC Standard and Premium under 4.0, the rebate levels can then be applied accordingly to drive ROI for your building projects. Similarly, the non-DLC 4.0 compliant products removed from the QPL on Apr. 1, 2017 will likely no longer qualify for many rebates.
Final thought: Be “choosy” on your lighting project and lighting product choiceYou can probably tell that the lighting industry and its certification groups want you to be informed and careful when choosing lamps or fixtures. What type of product are you installing? What is its proper rating and intended application? Where is it being used? What is the warranty and expected life?
These are all questions that DLC wants you to ask as you look at your lighting project. Through proper research and partnership, your project could offer a beneficial return for years to come.

In June, DesignLights™ Consortium (DLC) announced the final version of its Technical Requirements Table V4.0, which significantly increases the efficacy requirements for products to remain DLC qualified. Shortly thereafter, several additional proposals were introduced and have the potential to expand the DLC program to additional product types.
Technical Requirements Table V4.0:
The primary changes from the V3.0 to V4.0 requirements are the increases in efficacy, although there are also minor changes that will allow the DLC some flexibility to address specific situations in the future.
Unlike the 2015 V3.0 updates, which reorganized the specification, V4.0 updates are relatively straightforward as they raise the efficacy bar for every category. The DLC’s reasoning for this is that the requirements had not been meaningfully increased since 2014 but the efficacy of products has been steadily increasing.
The increases in luminaire efficacy are significant, with DLC Standard Efficacy products increasing 20 to 30 lumens per watt and DLC Premium Efficacy products increasing 10 to 40 lumens per watt. A full comparison of existing V3.X to new V4.0 requirements is below:
Similar to the increase in efficacy for luminaires, there has been an increase in the efficacy requirements for Lamps. The efficacy increases for E39 type lamps are the most significant, rising 15 to 25 lumens per watt.
Allowances and Other Changes:
In addition to the changes in efficacy, the technical requirements also include a new section that refers to allowances for lower efficacy for specific product type and feature combinations. This section is currently empty as there are no specific allowances included yet, but this allows DLC some flexibility in the future based on feedback and suggestions that they receive. This is, in a way, similar to the specialty luminaires in that the DLC is keeping the door open for situations that were not anticipated in their specification development process.
The other minor change included in the V4.0 technical requirements is the ability to report TM-30 data. This is not a requirement, but is notable for the partial adoption of such a recent metric. This change allows those who target a high TM-30 score the ability to distinguish their product while also offering additional decision tools to those looking for more information on color quality.
DLC Proposals for V4.1 (and Beyond):
DLC has several proposals that would expand the reach of the DLC program to include additional products. It is important to note that these are not effective yet, but are a good indication of how DLC intends to change its program in the future.
Outdoor Very High Output:
Part of the proposed V4.1 would separate out the “Outdoor High Output” category of luminaires, which currently includes everything over 10,000 lumens, and split it into two categories. The categories would be the existing High Output category, which would include products from 10,000 to 24,999 lumens, and a Very High Output category for products that produce 25,000 or more lumens. This change aims to address the large number of products that far exceed the minimum output to be considered an “Outdoor High Output” luminaire while also capturing some of the additional energy savings that can be found by increasing the efficacy on these “Outdoor Very High Output” products.
U-Bend SSL Lamps:
While DLC has covered linear SSL replacements for tube-style lamps for some time, they have not included the U-bend versions of these lamps. The V4.1 proposal to add the U-bend is a welcome one, particularly for those who experience the high shipping costs and breakage rates associated with legacy fluorescent products. No specifics have been given, but the requirements are likely to mirror those of the 4-foot T8 lamp replacements and would likely include measurement in a luminaire.
T5 SSL Replacement Lamps:
While mentioned in the V4.1 proposal as an area of interest to DLC members, there is not a proposal to include these products; however, DLC may consider including these products in future revisions, and they would likely assign requirements that differ from those covering T8 lamps.
Hazardous Location Luminaires:
In response to a large number of products applying for the special category for Hazardous Location Luminaires, DLC indicated in the V4.1 proposal that they intend to develop requirements for defining what a product must be considered to be a hazardous location luminaire. This is an early indication, but could include IP ratings, safety ratings and classifications per the National Electrical Code or Canadian Electrical Code.
Refrigerator Case Lighting Revision:
In the V4.1 proposal, DLC revised the definition of refrigerator case lighting to only allow pin-type connections that support electrical connections for refrigerator case lighting products. Products using pins for mechanical support will not be permitted. Products that use the pins for mechanical and electrical support would be better categorized as tubular LED lamps. This revision would provide a potential loophole and would impact already certified products.
In addition to the V4.1 proposal, DLC issued a number of other proposals that would include expansions and additional requirements.
While DLC has required proof of safety certification since V3.0, they issued a proposal to require proof of safety certification for private labelers. Many partners not having safety certification multiple listed in their own name causes additional work and concern regarding the program and this proposal is intended to eliminate those concerns.
Wider CCT Range:
DLC proposed adopting the newer ANSI C78.377-2015 standard for CCT and chromaticity, which has the biggest impact of allowing for very low CCT products in the 2200K and 2500K CCT ranges. It would not extend the high end limit of 5000K or 5700K (as applicable to the product); however, lower CCTs would allow for indoor products to give the appearance of dimmed incandescent or for outdoor products to have a lower CCT to address desires to replicate an incandescent or gas lamp type appearance.
DC Powered Products:
One of the more significant DLC proposals addresses the potential qualification of DC powered products. This will allow for some of the unique systems that enable connection to microgrids (including those that tie into renewable energy, such as solar and/or wind energy). This also includes Power Over Ethernet (POE) products, which allow for easy repositioning of Luminaires within a space due to the low voltage that is provided to the luminaires.
DLC must answer many questions before including DC powered products, but most of these questions focus on how to consider this type of energy efficiency. DC systems also have additional considerations, such as the external AC to DC conversion from the grid, and, depending on voltage, wiring can have a major impact on the efficiency of the system.
4-Pin SSL Replacement Lamps for CFLs:
Another significant expansion proposal is to include SSL replacements for 4-pin compact fluorescent lamps. These products are common in many commercial applications but are not currently covered by any energy efficiency program. The current proposal would include some similarities to measuring linear fluorescent lamps, such as performance in a luminaire. DLC is also including some pre-approved equivalent luminaires and pre-approved equivalent ballasts.
Alternates to these lists are allowed but are considered by the DLC on a case by case basis. It was noted that the DLC would be updating lists, so additional approved fixtures for these products would be included over time. The general categories of fixture are horizontally mounted downlights and vertically mounted downlights. The products can test in any category fixture and, given the allowable categories, are likely to focus on one application or the other, as CFL downlights are not the most efficient at redistributing light due to the large size of the source.
The biggest change in the near future involves required efficacy levels, which will impact many of the currently certified products. Existing products that meet the requirements will continue on to V4.0 without change, but it is also a good time to update product performance if changes have been made to LEDs or drivers. DLC Premium products will be downgraded to standard if they do not meet the new premium requirements, but will otherwise carry over.
Many proposals were made, but they remain just that: proposals. Which of the proposals will be adopted, and what modifications to the proposals are enacted, will be important to watch. The future holds additional opportunities for products that have not been able to achieve DLC qualification in the past and will open up the opportunity for incentives to a wider range of projects.

Hello MSSLC Members: I imagine most everyone is familiar with the recent position statement issued by the American Medical Association (AMA) on "high-intensity street lighting," due to the extensive media coverage following its release. We continue to field inquiries that include many passed along from our member municipalities and utilities, originating from their citizens and customers. The messages contained in the release have caused a stir.
DOE's Solid-State Lighting Program issued an SSL Postings within a few days of the AMA's release. This notes the importance of matching the characteristics of the product with the specific application, underscoring the AMA's call for the use of appropriate products. Since then a number of other organizations have also weighed in with very useful perspectives. You might want to check these out if you haven't already:
In addition to the above I thought I might also provide some numbers for your use should you continue to get inquiries from your respective agencies and citizens. Probably most people do not have access to the actual spectral contents of the different types of lighting in common use or know how they compare with one another, even if they understand that virtually all lighting sources produce some amount of melanopic content. Melanopic content is of interest here because it is regarded as a primary indicator of the relative potential for the listed light sources to stimulate the human biological responses that are the subject of much of the AMA's statement. Note, however, that influences from other photoreceptors like the rods and cones are also known to contribute to biological responses such as circadian and neurophysiological regulation, but in ways that are not fully clear to the medical research community.
Table 1 lists various sources used in street and area lighting and selected performance characteristics related to their spectral content. Data for each source includes a measured Correlated Color Temperature (CCT), the calculated percentage of radiant power contained in "blue wavelengths" (defined here from the literature related to sky glow as wavelengths between 405 and 530 nanometers [nm]), and the corresponding scotopic and melanopic multipliers relative to a high-pressure sodium (HPS) baseline, normalized for equivalent lumen output. Note that research on the contributions of different types of photoreceptors to visual and non-visual responses continues (e.g., see Amundadottir, 2016; Schlangen, 2016; Lucas et al., 2014) and may warrant updates to this table in the future.
Table 1. Selected blue light characteristics of various outdoor lighting sources at equivalent lumen output.
* Percent blue calculated according to LSPDD: Light Spectral Power Distribution Database, http://galileo.graphycs.cegepsherbrooke.qc.CA/app/en/home. The specific calculation, developed for evaluating the potential for affecting sky glow, divides the radiant power contained in the wavelengths between 405 and 530 nm by the total radiant power contained from 380 to 780 nm, for each light source.
** Melanopic content calculated according to CIE Irradiance Toolbox, http://files.cie.co.at/784_TN003_Toolbox.xls, 2015 as derived from Lucas et al., 2014.
Key: PC -- Phosphor Converted; LED -- Light Emitting Diode
As most products differ slightly from one another, the scotopic and melanopic values presented should be taken as being typical for the associated light source type, rather than exact. We have included ranges, for which we have data, to indicate the upper and lower limits that might be found in a representative set of LED product samples. The number of product samples underlying each CCT ranges from 2 (for 2700 K) to 19 (for 3000 K), with others falling in between (76 samples in all). Conventional light sources are all listed with single values rather than a range because DOE has performed less testing on those, but they would likewise be most accurately characterized by a range (albeit narrower than LED).
It is important to understand that performing a calculation with these values only provides an idea of the relative potential to cause human health impacts, rather than the actual (if any) impact of the melanopic content. These values do not yet take into account several critically-contributing factors noted in the LRC paper linked above, such as the intensity one might expect to find inside a bedroom from a streetlight outside. Furthermore, the melanopic content itself directly scales with light output for a given source, so reducing output by dimming dynamically reduces the corresponding content.
Finally, note that the scotopic and melanopic contents reported are listed relative to HPS, which was selected as the baseline for comparison due to its predominance in the existing outdoor lighting market.
The influence of blue wavelengths is immediately evident in all "white light" sources containing them. In addition, as demonstrated by the relative melanopic contents of conventional lighting sources in the table, the blue light issues being raised by the AMA are clearly nothing new to our lighted environment. What is new is our increased understanding of their potential influence regarding human and environmental health issues, as the related research progresses.
Estimating the potential impacts
A commonly cited advantage of LED lighting is the superior control available over its light distribution. This advantage arises because a luminaire needs to fit its output to a target area, for example a rectangular stretch of roadway extending 100+ feet out from under each side of a streetlight. To satisfy the application, fixtures employing omni-directional emitters like glass lamps require significant reshaping of the lamp's output through reflectors and lenses, and despite great skill in this regard, the results remain far from perfect with large components of the light continuing to exit the fixture in unwanted directions. The latter often results in light trespass, glare, uplight (in older installations especially) and non-uniform illumination on the ground, all of which amount to wasted light and energy. In contrast, because LEDs emit in only one hemispherical direction, the optics' job of shaping their light output into the pattern wanted is much easier from the start, and thereby enables the elimination of much of this waste.
One direct benefit resulting from the improved distribution is that lamp-based fixtures are now routinely being replaced with LED products that emit only half (or less) of the light output of the replaced conventional light source. This is a key concept for estimating the potential for impact from a lighting conversion program. For example, if product X has a melanopic content twice that of product Y, but can be run at one-third the output, then converting to product X might actually reduce melanopic output. As previously noted, dimming a given product similarly reduces its emitted melanopic content, in direct proportion to the reduced light output.
Numerous real-world examples exist of such reductions being achieved in actual street lighting conversion programs around the U.S. As a salient example, the city where I live, Portland, OR, has replaced its previous 100 W HPS fixtures emitting about 9,000 lumens (initial) with 4000 K LED products that are set to an initial output of 3,000 lumens, achieving a two-thirds reduction. As a result, in absolute terms, the LED products in Portland have likely had little impact on the melanopic output compared to the previous (and notably non-white) HPS fixtures they replaced, because the reduced light output offsets the LED's higher melanopic multiplier.
A second example is Cambridge, MA, which installed a dimming control system when it converted its street lighting to LED in 2013. According to a complete inventory of its lighting system at the time, the city replaced a total of about 54 million lumens (initial) of HPS lighting with about 32 million lumens (initial) of 4000 K LED lighting. The city's "maintained" setting of the controls system is at 70% output, meaning it actually only uses about 22.4 million lumens to light its streets at dusk when the lights first come on. Moreover, at midnight the dimmer setting is further reduced by another 50% (i.e., to 35% of full output), where it remains until early morning. Assuming even a high melanopic content factor relative to the original HPS of 3.4, during the initial evening hours its relative melanopic content emissions would amount to 3.4 x (22.4/54) = 1.41x those of the original HPS system. From midnight to the early morning hours, this value is reduced again by 0.5, yielding a factor of about 0.71x. In other words, the Cambridge system has offset the increase in melanopic content of converting to 4000 K lights, at least during the middle of the night, by reducing their output while still gaining the benefits of improved visibility, reduced energy and maintenance, and increased lifetime and reliability.
To summarize a few key takeaways:
The real value in LEDs, as has been stressed all along, comes from the combination of these elements. The wide-ranging capabilities and characteristics of LEDs are greater than any other lighting source that has come before them, and thus they offer unparalleled potential for addressing the issues raised by the AMA. As noted in the SSL Postings, LEDs are a critical part of the solution provided that these functionalities are applied. This is the message that should be shared.
I hope this information is helpful in planning and understanding the potential impacts of your own conversion efforts. I would like to extend my sincere thanks to George Brainard, Ph.D., and Robert Lucas, Ph.D., who reviewed and commented on this issue of The Light Post for accuracy. Their assistance is greatly appreciated. Bruce Kinzey, MSSLC Director Pacific Northwest National Laboratory MSSLC@pnnl.gov

While all Lutron dimmers can save money on energy expenses and maintenance costs, not all dimmers share the same functionality. Before developing a light control strategy, you should understand a few basic facts about dimmers.
Types of Dimmers
Each type of lighting source (load types) has individual characteristics, which require special types of dimmers. It is important to use a dimmer that is designed, tested, and UL listed for your specific lighting source/load type:
WEST CALDWELL, N.J. (June 25, 2015) – Designed to create a complete UL-listed fixture by the most economical means, MaxLite introduces the Lamp Ready Fixture Series as a companion to its line of LED Linear T8 replacement lamps.
Lamp Ready fixtures enable installers to avoid bypassing the ballast and adopt the energy-saving benefits of LED technology while keeping the UL-listing of the product intact. The Lamp Ready series was developed in response to a strong market demand for a new construction housing that is UL-listed specifically for LED replacement lamps that do not need a ballast. The UL certification mark indicates the product has been tested to meet globally accepted standards of product safety set forth by Underwriters Laboratories, in pairing an internally driven LED lamp with a dedicated new construction housing. In addition to simplifying the upgrade process for the contractor, the fixtures offer ease of maintenance and peace of mind for the end-user, who is able to continue to re-lamp the housings with MaxLite brand LED T8 lamps with the certainty that the combined lamp and housing are still UL-listed.
MaxLite launches the Lamp Ready series with Vapor Tight, Utility Strip and Linear Highbay fixtures. Additional models will join the line-up later this year. The fixtures are compatible with MaxLite’s internal driver LED T8 replacement lamps, and come pre-wired for contractor-ready installation as new or remodel fixtures.
“Contractors are often faced with fluorescent fixtures of varying ages and conditions on a job that must be either modified, or replaced, to comply to UL and building code standards,” said MaxLite Indoor Product Marketing Director Pat Treadway. “We found that many MROs were avoiding the adoption of LED T8 lamps because they were uncertain whether bypassing a ballast keeps the original UL product listing intact. Our new Lamp Ready Series was designed to remove that barrier by introducing a low-cost, complete fixture solution that is an easy choice over a modified fluorescent fixture that may not be UL-listed for LED use.”
Engineered to stand up to the harshest environments, the IP-65-rated Vapor Tight Lamp Ready fixture is constructed with a vapor tight housing that protects the light source against water and dirt, making it the perfect replacement for less efficient fluorescent strip lights in car wash operations, airports, tunnels, maintenance areas, parking garages and stairwells. Available in two- and three-lamp models, the fixture is designed with a transparent diffuser that supports maximum lumen output. The Lamp Ready Vapor Tight can be mounted to walls or ceilings with the provided hardware, or suspended from ceilings using a cable kit.
When combined with MaxLite brand LED T8 lamps, the Linear Highbay offers superior light output for commercial and industrial highbay and lowbay installations, assembly, warehouse, and general lighting applications. Available in four-, six- and eight-lamp versions, the fixture is constructed of the same durable steel as MaxLite’s commercial- and industrial-grade BayMAX LED Linear Highbays and works with the optional doors, wire guards and lenses from that product line.
The Lamp Ready Utility Strip features a compact, low profile design perfect for task and general lighting in residential, commercial or industrial projects. Available in one- and two-lamp housings, the strips can be mounted flush or suspended. Multiple end, side and rear knockouts enable the fixtures to be wired through and mounted in rows. They also accommodate an occupancy sensor for additional energy savings.
