On paper it is supposed to be able to give out more lumens, but in reality it is not. It is also a bigger sized emitter. So lumens not there, lux not there as well. You might be able to push it to shine in hardcore modded lights though (like the SST-90)
The reason the sst50 was highly liked was because before the XML, this was the one of the few single die emitters that ran over 500 lumens at 3 amps and was capable of 5 amps. Similar throw, as it’s only a little larger than the XML but not efficient at lower voltages like the XML. The Sst50 was better than the sscp7 or the MCE in beam shape and output.
Alas it’s outdated now and almost quadrouple the price of an XML.
You know how I beat that? I take my P7s and MC-E drop-ins and light them up against a wall and when it is obvious how they aren’t that hard driven (or that much brighter than an R5), I remind myself that an SST-50 drop-in and many other lights with that emitter would put out not much more light. So that helps me wait. lol
