If they are going to use a SST-90 they must not be driving it hard because it would fry it self in a light that size - I have a SST-90 emitter and they are really hot and need a really big heat sink - also IMO this light will be a WOF because of the small reflector and big light source.

I just got a PM from one of the custom builders here regarding these SST-90 LED's.

On direct drive in a 1D Mag hosts and the best heatsinking possible he got up to 9A of current.....with a single cell IMR 18650:twothumbs:twothumbs


He said the solder melted and the LED came off:poof: Now, that is hot, hot, hot, hot, hot,...He is trying to find a solder that will not melt at such high temperatures and a way to keep the current at 5A stable or 9A without melting the solder.

Did I mention the turn-on lumens are over 1400 as measured in a MrGman built and calibrated IS Sphere:popcorn:
