Reasonable compact XM-L light – UltraFire WF-501B XM-LT6 5-Mode 510-Lumen Memory White LED Flashlight with Strap (1*18650) Reviews

Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

Pros:
Mine came with a regulated 1.4A linear driver and thus draws about 5W (XM-L is specified up to 10W) - that's a good thing though, since a P60 drop-in light clearly isn't suited for more, so this is a reasonable choice and less prone for thermal suicide.
Modes are 2%/30%/100%/strobe/SOS (2% is a quite low low, which I like).
Cons:
Anodization could be better.
Other:
I measured a spot intensity of 4.7kcd, thus a NEMA-(0.25lx)-throw of 140m. A smooth reflector would probably increase that a bit.
Bottomline:
Compact XM-L light with reasonable power.
