LumiStar 1000 is the world’s brightest compact sight glass luminaire; it is two times brighter than a typical sight glass light, offering an unprecedented view of processes. Ultra-bright LED provides 1000 lumens at full brightness, two times the light output than a typical 100-Watt halogen light. With operating voltage: low voltage: 12-24V AC or DC, high voltage: 110-240V AC. The total internal reflection (TIR) lens with 23-degree beam angle, is ideal for vessel illumination through a sight glass with maximum light output and less than 5% loss of light output. The light is capable of continuous operation and emits cool white, 5500K color temperature, optimized for stainless steel vessels.
