Involvement:Expert (understands the inner workings) - Ownership:1 day to 1 week
The real perfect UV light to search for leakage (with Rhodamin or Fluoresceine)
and search for human/animal bodyfluids.
Working very fine, normal use with one
rechargable 18650 or two 16340 (3V or 3.7V) for higher output.
I did not have the troubles other users
have discribed, the building quality is 100% and the output definitely higher than the 1/2 or 1 Watt UV led-emitter wich is sold by Deal Extreme also.
Any other UV light (multiled and another build with a 1 Watt UV emitter)
I have in posession is NO match for this Ultrafire
None actually, exept the focussing of the led, the reflector should be twisted about 1/2-1 turn back so a sharp focus can be realised wich also extends the throw .
After adjusting fix the focussing with a few drops of cyanoacrylate
Carefull with you eyes, the -mostly invisable- output can cause damage.
For everyone who works with dyes and/or other scientific stuff, like minerals gemstones, UV hardening glue, biologists searching for traces of urine, semen and so on, should consider to buy this unit.
Also usefull as a blacklight during parties.
