FW3A, a TLF/BLF EDC flashlight - SST-20 available, coupon codes public

Isn’t that output quite low? The D4 measures around 4300 lm with 4 XPL-His. My naive calculation would expect a 3 emitter light with XPL-His to be 4300/4*3 = 3225 lm.

The D4 does 20kcd so I would expect this light to get to 15000kcd. Is the difference only the frosted optics?

Sorry if went wrong somewhere. I am not good with flashlight maths xD
