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: Manker U21
The U21 is compact thrower light from Manker, featuring the high-output but compact XHP35 High Intensity (HI) emitter. Coupled with larger reflector, this light should produce excellent throw. Supports a standard 26650 Li-ion battery.
