BIRNS Quantum™


The BIRNS Quantum™ floodlight delivers powerful, extended use LED illumination for demanding high ceiling applications inside containment. This intensely bright system is seismically qualified per IEEE-344, and has a 21,383 lumen output with a 109,000 hour lamp life. It provides safer, more comfortable and efficient working conditions in the reactor building with a near-daylight color temperature of ~ 5000K. With a low 210W power draw, along with optical efficiency of nearly 83%—102 lumens per Watt—it offers huge energy savings over metal halide and tungsten-halogen lamp options. The versatile BIRNS Quantum is UL-listed and accepts a wide range of input voltages, from 110V to 277V. It comes with an adjustable Universal mount for both ceiling and wall mount configurations, and integral bolt handles make it easy to securely lock the fixture in place.

This unique light is precision engineered with a robust all stainless steel exterior housing, and has a high radiation tolerance of 2.5 x 105 Gy (2.5 x 107R), making it well suited for harsh nuclear environments. Like all field-proven BIRNS nuclear lighting fixtures, the BIRNS Quantum is designed with safety and productivity in mind, so all corners and edges are rounded for worker safety, and all surfaces are smooth for easy cleaning and decontamination. It’s constructed of nuclear-compatible materials, and is designed with fully captivated parts for safety and efficiency of use.


This powerful, energy-efficient floodlight is ideal for wide range illumination in reactor halls, fuel buildings or anywhere that extended-life, UL-listed floodlights are needed.
