I recently had the opportunity to interview Andrew Banovic, Product Director Commercial Indoor Lighting, Acuity Brands Lighting, for an article Im writing for tED Magazines March 2022 issue. The topic: field-adjustable luminaires. Transcript follows.
DiLouie: How would you define a field-adjustable luminaire?
Banovic: Field-adjustable luminaires are essentially single SKUs which can be manufactured and shipped to a job site where they can replace multiple “static” configurations. Effectively, these luminaires can be fine tuned to match the exact requirements of the space.
DiLouie: How would you characterize demand for field-adjustable luminaires, and would you consider this category a trend?
Banovic: The demand for field-adjustable luminaires has absolutely increased in the past 12 months. In some of the product categories driven more from stock, we are seeing more demand for field-adjustable product than for their static predecessors.
DiLouie: How does the field adjustable mechanism work, who does it, and how can it be changed in the future after installation?
Banovic: There are multiple mechanisms used to adjust the lumens, color, or light output in luminaires. The most common is a set of mechanical switches, either designed into the luminaire’s driver or wired to the driver. These switches tell the driver to emit more or less power based on the desired light output and manage that power between multiple sets of LEDs. The division of power between LEDs of different color temperatures drive the overall luminaire CCT.
DiLouie: What adjustability is most popular? Lumens/Wattage, CCT, light distribution, or some combination of these?
Banovic: We have found that a combination of Light Output (Lumens/Wattage) and CCT are the most popular. These options allow a single luminaire to replace up to 9 static configurations. Those 9 configurations typically cover 90-95% of the configurations that could be needed for a given luminaire type.
DiLouie: What lighting products are covered in this category? Troffers, downlights, etc? Is it only indoor, or are there outdoor products with this capability as well?
Banovic: Lower wattage products like downlights and lay-ins (troffers and panel) were some of the first to adopt this technology because of the economics and cost/benefits of products that often ship from stock. Outdoor luminaries like wall packs and even industrial high bays have also started moving toward adjustable lumen products. Use in Outdoor and Industrial environments is typically about lumen reduction and SKU consolidation.
DiLouie: What are the benefits of field-adjustable luminaires for electrical distributors, contractors, and owners?
Banovic: There are some great benefits of field-adjustable luminaires for everyone in the value chain. Two of the largest investments in the distribution business are inventory and space to store that inventory. Field-adjustable luminaires allow for drastic working-capital reductions, as well as increasing the turns on the SKUs that are being stocked. This also can eliminate a great deal of returns as a good percentage of returns to a distributor are because of lumen output or color changes that are needed.
Contractors save time by using field-adjustable products. Some contractors have told us they have eliminated site audits for small/medium opportunities and simply ask the client how many downlights or lay-ins are needed. They know that with switchable products they can tune them to any lumen or color needs on site. They also spend less time going back to jobsites because of unhappy property owners. Electrical contractors can schedule their time more accurately because they know they will be able to complete a job in one trip – every time.
Owners get the ability to see what different light outputs and color temperatures look like in their space. Most people outside of lighting don’t know what 3500K or 5000K represent or what the difference even is. However, when they are shown in a space and asked if a setting is bright enough or too bright – and then adjustments are made on the spot – there is a higher likelihood they are happy with the end product. They are also more likely to get their project done on time because the products have a greater chance of being in stock and the contractor can complete the job on the first trip.
DiLouie: For the contractor and owner, what are typical and ideal applications? Is there a “killer app” for this product?
Banovic: We think almost any application can benefit from field-adjustable products. If designing a lighting system down to every lumen and foot candle, and ordering exactly what every square foot needs, then maybe the benefits are lower. But from what we have seen, most opportunities are not planned out to that level of detail. Think about applications with multiple ceiling heights on a single job. That is the perfect place for adjustable product. A perfect audit is not required by ordering X amount of 3000Lm, Y amount of 4000Lm, and Z amount of 5000Lm. Instead, order an adjustable lay-in and in one large lot. Also, it is more likely that the local distributor has that adjustable product in stock vs 3 different static lumen packages.
DiLouie: Looking more closely: what’s in it for distributors, what types and level of cost and inventory savings can be realized, and what additional value can they offer to customers?
Banovic: There is a great deal of supply chain math and statistics behind this, but most commonly if 3 sets of demand can be serviced with a single part it’s possible for a distributor to cut inventory in half without reducing service levels. If replacing 9 configurations, it can go even lower.
Here’s an example: A local distributor keeps 200 static fixtures on the shelf with a mix of multiple lumen packages and color temperatures. A customer comes in and needs 60 that day. Doesn’t care what lumen package or color temperature – but needs all 60 to match. Unfortunately, the distributor keeps 100 of those units in 3500k and the other half in 4000k. Also, the distributor keeps half of each color in high lumen and half in low lumen. So, despite having 200 fixtures in stock, the distributor has to say “no” to the order of 60 because the inventory does not match up. Now, instead, if that inventory was switchable, the distributor could immediately fulfill that 60-piece order.
DiLouie: As these luminaires typically impose a cost premium, they must justify additional value. Under what application situations would they not prove desirable?
Banovic: The main benefits of field-adjustable products are flexibility and availability. If working on a project where every luminaire is planned and specified down to the lumen, the flexibility benefit may not be needed, and the field adjustable features do not add value. Also, if planning a project well in advance, and there is enough time built in to wait for product to be manufactured and delivered, the added benefit of availability may not be valuable.
DiLouie: What do you see as the future of this category in 3-5 years? Do you believe it will grow to mainstream adoption, or do you see it growing to serve a specific market willing to pay for the additional flexibility?
Banovic: We see field-adjustable lighting playing an even larger role than it does today. The mechanisms that we use to adjust the light may be very different, but the advantages are not going away. Think about Multiple Volt or Universal Voltage drivers and ballasts. Once those caught on there was no going back. Now, almost all commercial applications use universal voltage equipment with the rare outliers only working for 120V or 277V.
DiLouie: If you could tell the entire electrical industry just one thing about field-adjustable luminaires, what would it be?
Banovic: Try them. If you haven’t stocked any yet, add a pallet to your warehouse. See how fast it flies off the shelf and see how fast you can get on and off job sites. You will never go back!

Architecture firms reported increasing demand for design services in October 2021, according to The American Institute of Architects (AIA).
The ABI score for October was 54.3. While this score is down slightly from September’s score of 56.6, it still indicates very strong business conditions overall (any score above 50 indicates an increase in billings from the prior month). During October, scoring for both the new project inquiries and design contracts expanded, posting scores of 62.9 and 58.0 respectively.
“Unlike the economy-wide payroll figures, architecture services employment has surpassed its pre-pandemic high,” said AIA Chief Economist, Kermit Baker, Hon. AIA, PhD. “Staffing continues to be a growing concern at architecture firms and may serve to limit their ability to take on new projects.”
Key ABI highlights for October include:
* Regional averages: Midwest (61.9); South (58.2); West (53.4); Northeast (48.6)
* Sector index breakdown: mixed practice (58.7); commercial/industrial (57.4); multi-family residential (55.8); institutional (51.4)
The regional and sector categories are calculated as a three-month moving average, whereas the national index, design contracts and inquiries are monthly numbers.

A free webinar hosted by the DesignLights Consortium (DLC) on December 9 will dive into issues related to poor nighttime lighting in underserved, marginalized communities, with an expert panel offering insights about these impacts and how to balance safety with responsible lighting while bridging the inequality gap.
“Environmental injustice takes many forms and lighting is no exception. Underserved neighborhoods, often communities of color, frequently endure inferior quality lighting, ranging from misconceptions about how brightly spaces must be lit to promote safety to neglecting lighting in need of repair,” DLC Executive Director and CEO Tina Halfpenny said. “This webinar will explore how poor quality light at night impacts health, wellbeing and safety in marginalized communities and ways to mitigate those impacts with well-designed, responsible lighting.”
“Responsible Lighting at Night: Bridging the Inequality Gap” will feature compelling presentations by professionals expert in a diverse array of fields. Exploring issues such as how light has been used in systems of racism and oppression and systemic choices that have led to lack of good lighting in underserved communities, the webinar will be moderated by Lauren Dandridge, principal of Chromatic, a lighting design firm that promotes the equitable application of lighting design for all communities. Dandridge is also an adjunct assistant professor in the School of Architecture at the University of Southern California, where she teaches architectural lighting design. Panelists include:
Don Slater, associate professor of sociology at the London School of Economics and co-director of the Configuring Light/Staging the Social research group. His research focuses on light and lighting as core elements of urban fabric and aims to foster dialogue and collaboration among social research, lighting design, and urban planning, particularly in the realm of space and infrastructure.R. Joshua Scannell, assistant professor of digital media theory at The New School’s School of Media Studies in New York. His work explores how changing digital technologies transform the relationship between the body and its environment, and how this relates to race- and gender-based political and economic exploitation of various populations.Robert Williams, assistant professor of political science at Bennett College in Greensboro, North Carolina, whose studies center on political theory, especially modern, contemporary and critical theories. His recent concentration is on environmental justice, the spatiality of politics (and the spatiality of night), and cyber-politics of the Internet.The upcoming webinar comes as the DLC is working on final LUNA technical requirements that will specify performance criteria for energy efficient commercial and industrial lighting products that also have light pollution mitigating features. In general, the draft technical requirements support the five principles for good outdoor lighting of the International Dark Sky Association and the Illuminating Engineering Society, which recommend that lighting:
Be installed only when and where there is a clear purpose;Be targeted, directing the light beam downward so it doesn’t spill beyond where it’s needed;Be no brighter than necessary;Be controlled with timers, motion detectors, and other technology that allows lights to be dimmed when possible and turned off when not needed; andUse warmer colors, limiting shorter (blue-violet) wavelengths shown to contribute most to light pollution.Through discussion of the inequities of outdoor lighting, the December 9, 2021 (1 – 2 p.m. EST) webinar will add context to how these principles can be applied to all communities.

The Dodge Momentum Index increased 10% in October to 181.2 (2000=100), from the revised September reading of 164.6. The Momentum Index, issued by Dodge Construction Network, is a monthly measure of the initial report for nonresidential building projects in planning, which have been shown to lead construction spending for nonresidential buildings by a full year. In October, commercial planning rose 14% and institutional gained 3%.
The value of nonresidential building projects entering planning has staged a solid recovery this fall. It has lifted the Momentum Index to its highest level in nearly 14 years, following a near-moribund summer of activity. The commercial sector has shown strength, having reached its highest level since the inception of the Index. The October gain in the Momentum Index was driven by increased planning in warehouses, offices, and healthcare structures. Compared to a year earlier, the Momentum Index was 47% higher in October 2021. The commercial planning component was 59% higher, and institutional was 26% higher.
A total of 20 projects with a value of $100 million or more entered planning in October. The leading commercial projects were a $450 million Walmart Distribution Center in Lyman, SC, and a $400 million Facebook data center in Los Lunas, NM. The leading institutional projects were the second and third phases of the California Northstate University Medical Center in Sacramento, valued at $500 million for each phase.
The dollar value of projects in the planning stage is impressive and portends a healthy rise in nonresidential building construction starts on tap for 2022. However, that expectation must be balanced against rising material costs, shortages of key goods, and a lack of skilled labor that will work to keep growth rates modest next year.

My contribution to the October 2021 issue of tED Magazine covered growing demand for plug load control in new buildings, a need that can be handled by lighting control systems. Reprinted with permission.
In the past 15 years, commercial building energy codes increasingly incorporated automatic control of lighting loads. While the combination of LED lighting and detailed control strategies dramatically curbed lighting’s share of building energy consumption, code makers started to address plug loads, a substantial load and the fastest-growing type. Again, lighting controls can help by integrating plug load control.
The problem
Plug loads include any devices that plug into standard electrical receptacles, such as task lighting, computer printers, photocopiers, cell phone chargers, personal fans/heaters, and appliances like coffeemakers. Many applications feature plug loads, though office buildings are quite intensive.
A great deal of office equipment is used intermittently during operating hours and not at all overnight. Equipment with enabled standby mode will go idle but still draw power. Even equipment that powers to Off may continue to draw a small amount of power as long as it’s connected to a socket, so as to be able to restart quickly; this is called a vampire, phantom, or parasitic load.
Plug and process loads accounted for 40 percent of commercial building energy consumption in 2017, according to the Department of Energy. A study estimated plug loads ranging from 25 percent in an overall less-efficient building to 50 percent in an overall high-efficiency building.
A solution

By automatically removing these devices from power when they’re not being used, significant energy savings can result, ranging from 20 to 50 percent. A 2012 General Services Administration office building study found that even with standby mode enabled, automatic receptacle control captured significant energy savings ranging from 26 percent in workstations to nearly 50 percent in kitchens and printer rooms, with highest savings for 24/7 devices such as printers, copiers, and kitchen appliances.
The energy savings were compelling enough to convince code makers to adopt the strategy. California’s Title 24, Part 6 and codes based on ANSI/ASHRAE/IES 90.1 (2010 and later) and the 2021 version of the International Energy Conservation Code (IECC) require automatic receptacle control. Specifically, a significant portion of receptacles in certain spaces be automatically controlled by scheduling, occupancy sensing, and/or automatic signal from another building system. The lighting control system offers these inherent control capabilities that can accommodate plug load control. Hotel and motel guest rooms have separate but similar requirements.
“Integrating plug loads with the lighting controls makes sense because it reduces the number of devices that need to be installed and therefore the cost and complexity of the total system,” said Charles Knuffke, Systems Evangelist, Wattstopper/Legrand (www.Wattstopper.com). “Instead of having separate timeclocks or occupancy sensors for the lighting and plug load controls, a single input device can communicate to both lighting and plug load controllers.”
He added that one set of inputs makes it easier for the owner to understand and manage their operations. If a networked control system is installed, the sensors can serve lighting, plug load, and HVAC control.
Options
When enacted by the lighting control system, a plug load control solution uses scheduling, occupancy sensing, or a combination of the two (e.g., scheduling during day, sensing at night), depending on the system.
Scheduling is relatively simple and well suited to larger, open applications with predictable occupancy and loads that must remain On during business hours even when they’re not being used. A manual switch on the receptacle or nearby wall provides user override up to two hours.
Occupancy sensing is based on detected rather than predicted occupancy, which can generate higher energy savings. This approach is ideal for smaller, enclosed spaces where occupancy is intermittent and unpredictable. If the sensor is auto-On, it can function as its own override.
The controlled load is the receptacle, able to respond to a control signal or fed power by a branch circuit that can respond to the signal. Some wirelessly controlled receptacles also feature onboard power metering. In a duplex receptacle, both outlets can be controlled or just one, allowing the uncontrolled outlet to operate loads that must remain On. Energy codes require controlled receptacles be permanently marked to distinguish them as controlled; starting in 2014, the National Electrical Code produced standardized markings for use.
“Contractors and facility managers will want to ensure a balance between efficiency and convenience, installing well-marked, controllable receptacles in locations that are reserved for loads like task lighting, small appliances, and small electronics such as heaters and monitors not designed for 24/7 use,” said Devis Mulunda, Product Manager – Vive Wireless, Lutron Electronics (www.Lutron.com).

These automatic receptacles can operate independently, as in the case of onboard timer/timeclock functionality for scheduling, or be controlled as just another load by the otherwise installed lighting control system: controllable circuit breaker panelboard, lighting control relay panel, or a relay in a dedicated powerpack. The system may be wired or wireless. If the overall control system is networked, power metering can be achieved and there is potential for more sophisticated dashboard control. Plug-in advanced power strips can be effective for retrofit but are not code-compliant for a new build.
“The implementation strategy varies based on what type of technology you are deploying in the room,” said David Buerer, Director of Product Management, Leviton Manufacturing Co., Inc. (www.Leviton.com). “If your solution is wallbox sensors, then it can be as simple as adding a second wallbox sensor control receptacle. If ceiling sensors and power packs, then adding a second power pack in auto-On mode. If more of a system, then you’ll be adding a wireless controlled receptacle, smart pack, wireless powerpack, or the like to gain receptacle control.”
Buerer added that after installation, it’s important that users be educated about the purpose and operation of the controls and how to identify which outlets are controlled, which will help ensure acceptance.
Final word
“Since plug load control is required by energy codes, the electrical distributor’s customers will be looking to the distributor to define what the code’s requirements are, offer products to meet the code, and explain the many features and benefits of the methods that can provide plug load control,” Knuffke said. “Look for manufacturers that can provide a range of solutions: relay panels, plug load powerpacks for simple component solutions, plug load controllers for intelligent systems, and controllable outlets. Ask if controls are available that use wired and/or wireless communication.”

Vista Architectural Lightings 1140 LED Linear In-Grade Series is designed to produce more lumens per foot for better light quality, cost efficiency, and performance.
The 1140 Series consists of two models, the smaller, 15-3/8”-wide 1141 available in nominal one-foot lengths, and the larger, 26-3/8”-wide 1142 available in two-foot lengths. The 1141 produces up to 2,100 lumens per foot, and the 1142 produces up to 1,845 lumens per foot. By producing more light per foot, more illumination is able to climb up the wall, especially important when theres a significant amount of ambient light entering the site from the surrounding area.
Tested for durability in the harshest outdoor environments, the 1140 Series features aluminum/polymer construction that’s strong enough for drive-over environments when installed in concrete. Both models include sealed optic modules with flow-through, recessed housings to further protect interior components. Five distributions – wall wash, wall graze, narrow, medium flood and wide flood – offer uniform illumination with added versatility. Screwless optic module installation, through-branch circuiting, and three dimming modes make these in-grade fixtures a flexible solution.
