Outdoor lighting control is undergoing a mini-revolution that offers electrical distributors new selling opportunities while challenging them to keep abreast of technological change.
Traditionally, controlling an outdoor lighting system was a relatively simple affair. Typically, the controller provided automatic ON/OFF based on time of day (astronomical time switch) or presence of daylight (photosensor). Luminaires were typically controlled at the circuit level, with no individual luminaire control.
“All of this has changed,” says Bryan Pike, senior product line manager for WattStopper, “with new code mandates for sophisticated control sequences of outdoor lighting and the increased controllability of new LED light sources.”
The biggest sales opportunities for outdoor lighting control, he points out, are municipal street and roadway lighting, parking facilities, park site lighting, large municipal and commercial facilities, and automotive dealerships.
Commercial building energy codes as or more stringent than ASHRAE/IES 90.1-2010, the national energy standard, require all outdoor lighting be controlled by a photosensor. Building facade and landscape lighting must also be controlled by a time switch that turns the lights OFF within a given window of time during the night.
ASHRAE/IES 90.1-2010 also requires that all outdoor lighting power (other than building facade and landscape lighting, but including advertising signage) be reduced by at least 30 percent after normal business operations either based on a schedule or occupancy. Parking garage lighting power must be reduced by at least 30 percent based on occupancy, with lighting grouped in control zones no larger than 3,600 sq.ft. Additionally, daylight harvesting for parking garage daylight zones and separate control for daylight transition areas (entrances/exits) must be provided.
These simple requirements, which can save significant amounts of energy, have created demand for sensors, individual luminaire control and controllability while increasing the complexity of design of outdoor lighting control systems. The resulting products and experience gained from these projects offer ready-made solutions for projects in areas with less stringent codes, providing another path to energy cost savings.

Manufacturers have responded with new technologies well suited to outdoor lighting control, including wireless and intelligent lighting control. These technologies provide an ideal match with outdoor LED lighting that continues to increase in popularity and performance. For best results, distributors should not regard outdoor lighting and control as an isolated aspect of the building but rather part of a total integrated system.
“The best solution is to deploy an integrated wireless solution that can incorporate all control strategies, such as ON/OFF, dimming, photocell control, occupancy and scheduling,” says Tom Braz, VP and general manager for Hubbell Building Automation. “These systems allow easy access to the system for future changes and fine tuning. A lower-cost solution would be individual fixture control where the control device comes attached to the fixture and can still provide occupancy and photocell control. The lowest-cost method would be to install a lighting control panel that can provide photocell and scheduling control.”
He points out that wireless is optimal because it enables implementation of all control strategies, with the ability to control each luminaire individually, while eliminating the need to deliver a control wire to every luminaire.
Rick Freeman, global product general manager of intelligent devices for GE Lighting, adds that wireless control enables two-way communication, which provides opportunities for monitoring and robust back-end management features.
“With new outdoor lighting systems that integrate controls with GPS locators, the fixtures suddenly become assets rather than simply a light source,” he says. “Outdoor lighting control systems can help cities and utilities realize where all their fixtures are at a given time and what kind they are, along with precise details on power sources, manufacturer and more. Given this information, it helps to assist with predictive maintenance schedules by alerting maintenance crews when a fixture is failing, as well as the specific type of fixture/bulb to help crews optimize their travel and maintenance time.”
Systems such as these are supported by a web-based interface that enables operators to remotely visualize real-time performance, set schedules, zone luminaires in groups, and generate custom reports that can optimize management of outdoor lighting as an asset. In the wireless control realm, ZigBee, 6LoWPAN, proprietary and cellular approaches are all on in various stages of implementation.
Wireless control can also facilitate implementation of sophisticated lighting control solutions for existing properties, as trenching and installing wiring isn’t needed. When upgrading outdoor lighting, distributors should look for opportunities to bundle controls. Utility rebates are available for outdoor as well as indoor controls.
“When assessing challenges and solutions, a distributor can add value to the project team by considering other specifics, such as what control sequences of operation may be desired, if there’s a need for multilevel lighting control, and what needs may exist for predictive maintenance, security or merchandising,” says Pike. “These factors will all influence the specific solution that may be ideal for a particular application.”
Freeman agrees. “Electrical distributors will see controls and LED retrofit go hand in hand,” he says. “They have opportunities to expand their businesses beyond what is on their shelves by providing more services for planning, installing and commissioning lighting controls. Customers are eager for the solution but do not want to have to piece it together themselves—this is where an electrical distributors can take advantage to be the expert resource and build a custom solution that integrates lighting control systems.”
The popularity of LED lighting is also facilitating other technological change. Advances in standards and technology for the Internet of Things will provide opportunities to integrate other devices within LED luminaires, such as sensors, security cameras and audio. Integrating and designing these systems will be a challenge, however, and it is difficult for some owners to understand the value of the kinds of data that can be produced until they actually have the data in hand, creating a Catch-22.
Further, occupancy sensing for outdoor lighting, currently limited to passive-infrared sensing technology, may expand with options for digital imaging (non-recording video), which offers more precise detection in the dynamic outdoor environment.
“Lighting fixtures and lighting controls are no longer separate things,” says Braz. “The customer views their lighting applications as a system. Our industry should approach every customer with a system solution. Every discussion should include a value proposition of integrated lighting fixture and control.”
Freeman adds, “Don’t think of it as control. Think of it as sensing, decision making, control and prediction. It is a solution where data and applications are very important.”

Lighting controls are devices and systems that turn lighting ON/OF or raise/lower output according to need. Over the past 10 years, these functions have become increasingly automated to save energy in commercial buildings, with demand focused on new construction due to energy codes. More recently, lighting controls began to offer advanced features such as onboard intelligence, allowing independent decision-making and addressability within a scalable lighting control network. Radio-frequency (RF) wireless communication is increasing penetration of even sophisticated lighting control solutions in existing buildings. Some LED companies are now bringing automation, intelligence/addressability and wireless communication together into lighting packages with smart luminaires or lamps as the platform for implementing light and control.
“There has been so much evolution in this area over the past several years, with the emergence of LED lighting and the increased interest in controllability of lighting perhaps taking the front position,” says Carlos Villalobos, director of product marketing for WattStopper. “Specific to indoor lighting control, among the top three trends certainly would be the continuing evolution of ever-stronger code requirements such as multilevel lighting reduction, plug load control and performance monitoring. There is also increasing market demand for flexible control technologies such as wireless and control embedded within the light source.”
“Electrical distributors that grasp the value of controls and educate themselves as well as their customers on the value of advanced product features will see increased sales as a result,” says Joe Briscoe, product division manager for PLC Multipoint. “Understanding that just about every lighting project has some requirement for controls and quickly matching the appropriate controls to the application will increase customer satisfaction.”

The big driver in the market continues to be commercial building energy codes. Currently, more than 10 states have adopted a code at least as stringent as the ASHRAE/IES 90.1-2010 energy standard, which requires multilevel control throughout the interior spaces of a commercial building. Many other states maintain codes based on the previous generation of 90.1, which also contains strict control requirements focused on automatic shutoff. As energy codes require smaller, more precise control zoning within indoor spaces and greater controllability across the board, demand has increased for more powerful control capabilities in systems that are easy to specify, install and use.
“Simplicity and saving money rule,” says Tom Hinds, product portfolio manager for Cree, Inc., which entered the controls market early in 2014 with its SmartCast system. “Lighting controls don’t need to be complicated; it’s proven that people won’t adopt if they are.”
As a result, manufacturers are unveiling a growing number of products that feature automatic setup and devices that accommodate various wiring challenges (e.g., optional neutral sensors for applications where a grounded neutral is present or not). Further, the appeal of RF wireless is growing in new construction by reducing wiring requirements.
Economics and project requirements driven by energy codes, Briscoe says, are continuing to drive demand toward room-level rather than building control solutions. Villalobos points out that these are distinctive markets with different needs, with demand for building-level control driven by owners interested in LEED certification, achieving high-performance building goals or integrating multiple building systems into a single sophisticated control system. The good news, both agree, is that intelligent room-level control packages are now available that can be networked in a scalable manner into a building lighting control system based on need.
“Modular in architecture, some distributed control solutions enable room-level control while still providing a path to scale to a building-level solution in the future,” Villalobos says. “While not every customer needs a building-wide, sophisticated control system today, many may benefit from technology solutions that empower them to scale on their own timetables.”
Networking controls requires addressability, which takes the technology into the digital realm with its various potential benefits including control zoning and rezoning using software, zoning as small as individual luminaires, automatic setup and onboard intelligence. It enables two-way communication, allowing devices to share information and produce data that can be fed to a central point for analysis. And it allows interaction between users and their lighting, giving them the ability to adjust light and other environmental conditions, such as temperature, using mobile devices.
“The biggest trend we’re seeing in the lighting control space is the increasing demand for individually addressed controlled lighting that also yields data,” says Hinds. “However, there’s still a lot of work to be done regarding how this data can be best used to drive more efficiency back into the building.”
Digital lighting control systems are traditionally hardwired but are now increasingly available with RF wireless communication—a technology combination that Hinds calls the next generation of digital lighting control.
Briscoe says, “Customers and contractors have become accustomed to control wiring and the issues related to digital systems. This comfort level has led to a larger acceptance of those systems. We’re seeing an evolution of wireless controls similar to other technical advancements. Some products are being developed as open systems using protocols such as EnOcean or ZigBee, while other products are either using proprietary protocols or custom configurations of existing open protocols. This is allowing for quicker development.”
In the existing buildings market, lighting controls can produce significant energy cost savings but are more challenging because, like many LED projects, they tend not to lend themselves to cookie cutter solutions. However, one traditional challenge—the economics, disruption and, in some cases, lack of feasibility of new wiring—has been countered by the development of RF wireless lighting control solutions.
Wireless has grown in popularity as a means of introducing lighting automation to existing buildings, but is also proving attractive in new construction as well. “Realizing the benefits of these technologies in retrofit situations makes it easier to migrate these solutions into new construction,” Villalobos says. “It results in reduced cost of construction, less use of copper, and shorter install times.” He adds that significant utility rebates are available that can reduce cost of lighting controls in both new and existing buildings.
And increasingly, automatic lighting controls are being coupled with LED luminaires and lamps. Says Hinds: “LED technology has a significant advantage over incumbent technologies because LEDs are fully dimmable. Many LED luminaires include 0-10V dimming as a standard option because LEDs provide full control of the light output through continuous dimming without stressing the LED—there’s no reason to not include 0-10V dimming as a standard.” As a result, advanced lighting controls are predicted to be even more common in an LED future.
Final word: “Take advantage of the products that are available and the expertise each manufacturer provides,” Briscoe advises distributors. “Demanding the best for your customers will ensure a successful solution.”
Daintree and CLTC will collaborate on efforts to raise awareness about the benefits of networked lighting controls. The widespread adoption of energy-efficient technologies such as lighting controls will help reduce energy use.
The partnership will demonstrate how open standards-based communications and controls can simplify the integration process for commercial buildings to meet California’s building energy efficiency goals.
The U.S. Department of Energy (DOE) has issued new energy standards for general-service fluorescent lamps that are expected to reduce availability of standard 4-ft. linear and 2-ft. U-bend 32W T8 lamps as well as some reduced-wattage T8 lamps. The rules go into effect January 26, 2018. After that date, distributors may continue to sell their inventories of non-compliant lamps until these are exhausted.
DOE estimates consumer cost savings with a cumulative net present value (including both energy cost savings and increased initial cost) of between $2 (7% discount rate) and $5.5 billion (3.3% discount rate) over the next 30 years.
Previous regulations, which took effect in July 2012, eliminated a majority of 4-ft. linear and 2-ft. U-bend T12 lamps and many 8-ft. T12 and T12HO lamps. Low-color-rendering (70-79 CRI) T8 lamps also failed to comply, but several manufacturers gained a temporary exception for their specific products, which expired in July 2014.
The new rules strengthen existing energy standards (minimum source efficacy in lumens/W) by 1-4% for 4-ft. linear T8 and 2-ft. U-bend T8 lamps, approaching the maximum technology level. Lamps that do not comply are prohibited from manufacture and importing as of the effective date. The rules also strengthened energy standards by 7-10+% for 4-ft. linear T5 and T5HO lamps while expanding covered wattages. Energy standards for 8-ft. lamps were not changed.
Previous exceptions still apply, including 1) lamps designed to promote plant growth, 2) lamps designed specifically for cold-temperature applications, 3) colored lamps, 4) impact-resistant lamps, 5), reflectorized or aperture lamps, 6) lamps designed for reprographic applications, 7) UV lamps, and 8) lamps with a CRI of 87 or higher.
Over the next three years, manufacturers will review their products and reengineer or discontinue them on a case-by-case basis. Interviews with lamp manufacturers suggest likely outcomes. In the T8 category, a majority of lamps pass the standards. However, these are primarily reduced-wattage (e.g., 25W, 28W) lamps. Today’s basic-grade 32W lamps do not comply. Some standard 32W T8 lamps may be reengineered, but overall, availability will be reduced. Extended-life lamps will continue to be available but may be limited to wattages lower than 32W.
The T5 category does not appear to be adversely affected. Manufacturers stated that today’s 4-ft. T5 and T5HO lamps will satisfy the new rules with little or no reengineering.
The net effect is consumers are likely to have fewer T8 lamps to choose from, with surviving options presenting a higher average initial cost. Consumers will have two compliance options that save energy. They can switch from full- to reduced-wattage lamps, or they can operate compliant lamps on a dimming ballast and control. DOE estimates an average payback of 3-4 years for switching from full- to reduced-wattage lamps.
If the existing installation contains continuous-dimming ballasts, owners will need to determine that these ballasts are rated for reduced-wattage lamps. This information is on the ballast label. Operating reduced-wattage lamps on dimming ballasts not rated for them will produce unsatisfactory performance. If the existing dimming ballasts are not rated for reduced-wattage lamps, the owner will need to replace the existing lamp with a compliant full-wattage lamp or replace the dimming ballast with one rated for reduced-wattage lamps.
Lighting practitioners should advise their customers about the new regulations and the benefits of a lighting upgrade. They should consult with manufacturers to confirm availability of compliant alternatives.
Owners should consider the benefits of an upgrade compared to replacing non-compliant lamps individually as part of maintenance. Replacing all lamps at once ensures consistent lighting quality, reduces the risk of matching incompatible components, and provides an opportunity to completely re-evaluate the existing lighting system.
DOE’s 2010 National Lighting Inventory estimated that 20% of all lamps in the commercial building sector and 44% in the industrial sector are 4-ft. T8. In 2010, DOE estimated that there were 532 million 4-ft. linear T8 lamps and 14 million T8 U-bend lamps installed in commercial and industrial buildings in the United States.

This month, we will explore the role that a sophisticated lighting control scheme plays in controlling lighting at a forensic center. Lighting control design by Michael Shiu, lighting designer for Stantec Consulting Ltd. Photography by Richard Johnson. Lighting controls by Fifth Light.
This 550,000 SF Forensic Services and Coroner’s Complex is one of the largest of its kind in the world. The lighting design meets the $497M project budget and creates a practical atmosphere for a modern, integrated, and energy efficient building. Fixtures are robust, secure, and easily maintained. All building fixtures are controlled by a DALI system, make use of daylight, occupancy and photosensors, and use T8 fluorescent, LED or compact fluorescent lamps to meet IES, LEED and ASHRAE requirements. In the coroner’s courts entrance canopy, an exterior lighting sensor and astronomical clock control the recessed compact fluorescent TTT lamp pot
Simple architecture and decorative lighting in public spaces create a welcoming yet authoritative atmosphere. Exterior lighting sensors and an astronomical clock control all exterior pole-mounted and wall-mounted light fixtures.
The five-story-high atrium’s bridges and stairs connect multiple spaces. Atrium circulation lighting is always on, except for statutory holidays. A DALI control adjusts light output.
In the atrium’s sitting areas, an astronomical clock and occupancy sensor control the lighting.
The daylighting design utilizes large glazing walls, windows and sunlight. In the public courts entrance, daylight sensors control and dim the lighting levels.
Daylight sensors and occupancy sensors control lighting in corridors with tall windows via a DALI lighting system.
Daylight sensors and occupancy sensors control office area lighting with a DALI ballast connected to a DALI lighting-control system.
Courtrooms utilize compact fluorescent down lights and cove lighting. Each fixture in the court rooms is fully dimmable with an addressable DALI ballast and controlled by a local digital control panel using the DALI interface.
Secure areas employ high-security fixtures. Labs and autopsy areas, for example, utilize recessed fluorescent clean-room fixtures, which are controlled by local switches and a centralized DALI lighting system.

Agostino Renna, President & CEO of GE Lighting for Europe, The Middle East and Africa, recently authored an interesting series of blog posts, “More Than Light,” in which he describes the potential for intelligent cities and the role of lighting in these schemes. He notes:
“For me, the most important thing to consider when discussing the future of intelligent cities – and GE’s role within that – is that we are not constrained by technology. The technology is available, commercially viable, and it delivers the right outcome. But where the market needs to change is in the area of courage. We are still following convention, using old processes to solve new generation problems.”
