Yup, probably no real use for it though, no scorpions here.

Actually I have some problems lining up the leds for the white array cause the lens pushes against the leds and they're not all pointing in the same direction. The shape of the beam is kinda longish. Any ideas to fix this?

Judging from the filenames, I'm gonna go out on a limb and guess: UK 2L.
Did I win anything?

Beautiful job, BTW. Gonna tell us anything about them?

Well, what do you want to know about them?

YCLO - if you want to send pics and a description of what you did, I'll be happy to post these mods with your others on my site.

What type of LEDs, how they're voltage-matched. Any regulation? Any measurements (runtime, output, etc)? How much will you charge to make me one?... that kind of thing
Nobody read my post about them being 2L's huh?

The UV must of cost an arm and leg to make; don't those UV LEDs go for like $20.00 each?
Looks like a retail $1000.00 light for forensic professionals (police, investigators, corornor, etc.)
Does old blood and such glow under the UV light?

Nichia's 375nm UV LEDs go for $33 apiece in small quantities; probably dropping to $28 or so if you get more than 10.
Toyoda Gosei 385nm 'Super Purple' LEDs probably cost a lot less, but I don't know who's selling them, so that probably isn't it.
That leaves us with Wilycon's 390-395nm super purple that cost less than $3 each in small quantities, and they're supposed to emit more "light" than the other two.

Some info:
Leds used are bought in Hong Kong, most probably some cheapo ones that are made in China. Cost of the leds are about US$2 each.
The torch used for the mod is as Darell said a Underwater Kinetics 2L. The white led array has 7 leds, and the UV one has 12.
It has no voltage regulation or fancy electronics in there, just a plain old resistor to drop the voltage. Can't remember exactly what the value of the resistors are, but the leds are running at approximately 30ma last time I checked. They're connected in parallel and then series with the resistor.
In order to fit the 12 leds in, I had to trim off the base part of each led. The white led array emits a beam that's kind of longish, because no matter how much I try to align the leds, the lens pushes against them when you screw on the bezel and makes them all point in different directions. Haven't used epoxy on it yet, because my bad soldering has caused the leads to break off when I use it.
I didn't take any photos of the actual modules themselves, cause they are really badly made and I wouldn't make them like that again if I were to make more. But thanks for the offer Doug.
