LEDs have made their way into specialty and industrial use cases due to their high brightness, long lifetime, and color quality features. In some applications, luminaires are required to deliver high performance under harsh conditions, with exposure to cleaning solutions, ocean spray, high or low outdoor temperatures, shock and vibration, and attempted tampering all presenting potential challenges. A selection of specialty luminaires and drivers for demanding environments follows.

Mercmaster LED Low-profile Luminaires, Appleton
Mercmaster LED industrial-grade luminaires feature an installed profile of six inches, ideal for low-ceiling applications. With outputs of up to 5500 lumens and four field-replaceable globe alternatives (clear glass, clear polycarbonate, diffused polycarbonate, and prismatic glass refractor), the low-profile fixtures can withstand harsh industrial conditions, wet and marine environments, and corrosive atmospheres. An emergency battery backup version offers 90- or 180-minute operation modes and a functional self-diagnostic test for code compliance.
Two-hour Emergency Driver Solutions, IOTAILB2H and ILBHI 2H Series emergency drivers boast an extended 2-hour runtime capability, exceeding the standard 90 minutes of emergency operation outlined in the Life Safety Code. The drivers deliver constant, non-diminishing emergency illumination and are UL 924 listed for factory and field installation. Installation is simplified with the intelligent AC activated battery circuitry, and the units automatically perform self-tests and self-diagnostics.
Battery Backup Area Light, DialightThe new area light model provides an auxiliary battery backup solution that delivers illumination for a minimum of 90 minutes in accordance with National Fire Protection Association (NFPA) 101 guidance on emergency lighting. Vibration tested to IEC 60068-2-6, the 20-pound fixture is designed to withstand harsh industrial environments, with both non-hazardous and hazardous location models available. The area light is certified to UL1598/A, UL924, and UL844 to meet marine, emergency, and hazardous application requirements.
TritonPro and Harris Exterior LED Product Lines, Orion Energy SystemsThe Harris and TritonPro product lines are aimed at construction and retrofit markets. The Harris Area Light Lumen Select, a high-performance outdoor LED fixture, illuminates large outdoor areas. The TritonPro line features four products in linear, linear high-bay, and troffer form factors to serve high ceiling, commercial, institutional, and retail environments, with reduced footprint and improved robustness across indoor and outdoor settings.
EUCO-2.1kW LED drivers, DeltaThe latest EUCO Arena Sport Series devices feature DALI 2/D4i and DMX/RDM control versions and are designed to optimize the sports lighting experience for on-site and TV audiences. The DALI model is certified to the D4i standard, an extension of the DALI-2 lighting protocol, to meet demands for IoT connectivity. The drivers consist of three programmable independent output channels with a max output power of 700W/channel and can achieve a low peak-to-peak current ripple (<1%). They can handle a wide range of operating temperatures (–40°C to +50°C) and are IP66 rated.
Lifeshield Architectural Downlighting, CurrentDesigned for healthcare, behavioral, institutional, and cleanroom settings, Lifeshield downlights feature low-glare, quiet-ceiling designs that deliver a 50-degree visual cutoff to source and true color rendition. The fixtures are ISO3 cleanroom rated for sterile environments and meet other electrical, ingress protection, and safety standards, including CSA, Wet Environment, IC, CCEA, UL924, IP66, IP69K, IK10, MIL461G, and IEC. The luminaires are available in 4- and 6-inch round and square aperture models with beam distributions ranging from very narrow to extra wide. CURRENTLIGHTING.COM
