Our WS3 light module is the core of REL’s Visible Spectrum LED Lighting Solutions.

This unit packs in extraordinary amount of power and versatility into a compact, durable housing unit that can withstand the rigors of any dynamic test lab. The included Laser Alignment Tool adds speed and accuracy for focusing the full intensity of the light on a particular target. The machined aluminum housing is sealed, rated for submersion, vacuum, and environmental chambers. The generous mounting options ensure the modules can be positioned, mounted, and arrayed without hassle. The WS3 also includes a thermal protection shut off feature to prevent over temp damage to the light head.

Our WS3 7.5" LED Hexagon light head is compatible with several different power supply options to match a variety of lab requirements. Options start with a 540W continuous duty, single module power supply and expand to a 17kW capacitive burst supply that can drive quad clusters to 4x the continuous rating. These power modules can be controlled manually or with external triggers and are scalable to any size array.
