  • OK, Nice UV, NOT 3 Watts!

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

    Pros:

    Reasonable price for a UV flashlight. Looks nice, most build quality is good.

    Cons:

    NOT 3 watts as advertised! Measured input power about .75W (.2A @ 3.8V)with freshly charged UltraFire LC 18650 cell. LED not centered properly, main beam off to one side. Flashlight body a little short for the UltraFire cell, sanding down the plastic spacer in the head section helps, otherwise do not tighten the head or cell cap too much.

    Bottomline:

    With a few mods, this light is nice. I guess advertising at 3 watts does sell more units?...(worked on me!!!),though all I care about is optical power out, don't have an easy way to measure that. Maybe others have measured and found the power is 3 watts. If so maybe post your results.
