A well-driven XM-L will be pretty much the same output. And they tend to be cheaper than SST LEDs.
Not to mention a damn sight more efficient.
I ordered a 28$ C8 XM-L, but got a 63$ C8 SST-90 instead. I did not complain. :) So far my brightest light. Right now I am modding an X-2000 with a XM-L T6 star, looks promising so far.
keep me posted on how that goes, I would like to do the same if you have good results
