Selfbuilt's Flashlight Reviews
Extensive comparative analyses of modern LED flashlights
My goal is to provide objective testing results, in a readable form, to let you decide what flashlight best fits your needs. My reviews are posted on candlepowerforums, to facilitate ongoing discussions with the user community.
My flashlights are expensive to feed with all the runtime tests I perform, so I gratefully accept donations to my Paypal battery fund.

Latest Review: V54 Acebeam K40Lvn
The stock K40L is a slightly smaller version of the K50vn that I reviewed previously. I have two versions of Vinh Nguyen's modification on hand for testing - a dedomed stock XP-L, and a dedomed XP-G2.
