Luminus

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 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.

SST-50
The SST-50 is 2.2mm x 2.2mm (5 mm&sup2;) 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. web page

The SST-50 is used in the ThruNite Catapult, LumaPower D-Mini VX Ultra, Olight M21 Warrior Luminus, and the Tiablo AS50.

SST-90
The SST-90 is 3mm x 3mm (9mm&sup2;) drawing up to 9 amps while outputting up to 2250 emitter lumens. web page

CBM-360
The CBM/CSM-360 is four SST-90 dies mounted on a single device. It is designed as a replacement for high power illumination lamps. web page
