[[File:Luminus_SST-90.jpg|thumb|Luminus SST-90 LED]]Luminus is a LED manufacturer based in Billerica, Massachusetts. They produce the SST-50 and SST-90 LED's (SSR-50 and SSR-90 are just the LED mounted to a star). These LED's compete with the [[Seoul Semiconductor|SSC]] P7 and [[Cree]] MC-E, but the LED is a single emitter instead of 4 separate ones working together. The size of the emitter is similar so there is a large hotspot, but because the entire emitter lights up, SST-50 lights are less prone to a donut hole of darkness at the center of the beam.

The SST-50 is 2.2mm x 2.2mm (5 mm²) drawing up to 5 amps while outputting up to 1250 emitter lumens. This is a big current draw for a flashlight and batteries and produces a large amount of heat, therefore the LED's are driven lower than maximum. Flashlights using this LED are capable of 500 lumens of output on one 18650 li-ion cell and up to 900 lumens using 2 18650's.
