Has not 3Watt! – UltraFire WF-501B 3W UV 395~400nm LED Flashlight with Clip (1*18650/2*CR123A) Reviews

Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

Pros:
Works nice at night doing geocaching to follow a UV trace.
Cons:
The rubber of the tail cap was not in it's place but easy to repair.
I measured at about 3V a consumption of rouhly 300mA which makes about 1Watt! Even at 3,7V -like a LiIon battery- I could measure the same power. Definitely no 3W lamp!!!
Other:
Could be worse but in the end it's ok. I haven't looked but my guess is that a torch of this type would've cost much more in Germany.
Bottomline:
works well for my purpose (geocaching) but could've been more powerful.
