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: Olight S15R

Olight has recently updated their popular Baton series of lights with new rechargeable versions (known by the "R" addition to the model name). These R-version lights are similar to previous generation Baton lights, except they all come with an Olight-branded 3.7V Li-ion battery, and desktop USB-charging dock.

Given the large number of comparisons required, I've decided to process these into three individual reviews for the S10R (for 1xCR123A/RCR), S15R (for 1x14500/AA/NiMH) and S20R (for 1x18650) separately - starting with the S10R (link above). Please see that review for a comparison of the new S10R to other members in this class.
