The ULB is better than ever! This line of premium high bay luminaires is available in many of the same output packages as our standard ULB, but with even higher efficacies! Improved LED technology has allowed us to increase lumens per watt across the board. The G2 is available in a wide variety of sizes, lumen output packages and control options. Diffuser lenses are available to minimize glare and improve aesthetics. The housing is precision brake formed from aluminum and pre-painted with a highly durable, highly reflective white finish. Several control options – including IoT compatible sensors – can be incorporated. Contact the factory for more info. Every ULB G2 is made in the USA, in our Henderson, NC facility, utilizing mostly domestic and some foreign components. At up to 179.5 lumens per watt, it’s our most efficient product to date!

Maximize the savings potential of your ULB with one of our many control options. The Wattstopper FSP sensor equips your ULB with multi-level control based on motion and/or daylight contribution. Rated for both wet and cold locations, every FSP comes pre-installed and pre-wired on the end cap. Three different lenses are available, tailored for the ideal detection area and mounting height. All parameters can be adjusted from the floor via a wireless configuration tool (the FSIR-100 – sold separately).
The ULB is also available with an optional on/off occupancy sensor (option “OS”). With the Leviton OSFHU-ITW (or an equivalent), each individual ULB can be controlled based on occupancy in its detection zone. For added energy savings through daylight harvesting, an occupancy sensor with photocell (option “OSP”) is available. The OSP turns the luminaire on or off based on occupancy or available natural light.

IoT compatibility
We offer more robust network control options and Internet of Things (IoT) compatibility with products from Enlighted and Leviton. Contact us for more info. Also, if there’s another control system you’re looking for – such as Nedap, Daintree, or another IoT-based system – just contact us. We can incorporate it.

The ULB is a high performance, versatile general area LED high bay available in a wide variety of sizes, lumen packages and control options. Diffuser lenses are available to minimize glare and improve aesthetics. The ULB’s housing and LED tray is precision brake formed from aluminum and pre-painted with a highly durable, highly reflective white finish. Three color options are available: White (standard), Matte Black and Metallic Silver. LED boards are available with conformal coating. Several control options – including IoT-compatible sensors – can be incorporated into the ULB (click here for more info on ULB controls). A “heavy duty” version of the ULB – with optional pendant and surface mounting options – is available here. The ULB is made in the USA – in our Henderson, NC facility, utilizing mostly domestic and some foreign components.
