BIRNS Quantum-C™


The BIRNS Quantum-C™ floodlight, like the BIRNS Quantum, provides powerful, extended use LED illumination for a wide work area inside containment. This durable, brilliant system is engineered with low profile cooling fins, so it’s ideal for high ceiling and crane applications, as it has a more compact footprint. This robust high bay system is seismically qualified per IEEE-344 and has a 21,383 lumen output to enhance safety and productivity. It has a ~100,000 hour lamp life, which minimizes maintenance, and delivers 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 and cost savings over metal halide and tungsten-halogen lamp options. The versatile BIRNS Quantum-C accepts a wide range of input voltages, from 110V to 277V. It comes with an adjustable Universal mount for ceiling, wall and crane mount configurations, and captivated flex-top nuts make it easy to securely lock the fixture in place.

This unique light is precision manufactured in the U.S. and has a robust, all stainless steel exterior housing, and is well suited for extended use in nuclear environments. It features an exclusive breather system, so it withstands containment integrated leak rate testing at full pressure. Like all field-proven BIRNS nuclear lighting fixtures, the BIRNS Quantum-C 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, extended life, energy-efficient LED floodlight is ideal for wide range illumination in reactor halls and fuel buildings, and is ideal for use on ceilings, walls or cranes.
