Most "powerfull" UV flashlight....?

Hi all, this is my first post. Cool forum!
I am an avid invert enthusiast and go scorp hunting alot. I currently have a cheapo $10 uv led FL from ebay. No name, throws a decent beam about 6' that will light up a scorpion. Im looking for a nice high power UV flashlight that takes either C or D batteries (for longevity on long hunts). I's also looking for somethin 390nm or less (makes the sccorps much more distinct). Ive seen the streamlight 51010 and 18, but they only have small 6 leds and im not sure how far the uv beam goes. Ive also seen the invoas but am not sure of the actual beam distance on them. Any help will be more than apreccitaed, thanks guys (please dont flogg the noob....:shakehead)

I think, with those specs, you would need to build your own UV light.

This unit might do the trick then.
Outputs close to 500mW (0.5 watt) of radiation at 368.6nm, and uses three D cells.

Try xenopuselectronix.com (sorry, I don't know how to do links). They have what I would consider to be "professional" level UV lights...and they're "professionally-priced" as well.

DX has a 1w p60 style light, http://www.dealextreme.com/details.dx/sku.10709

Pros are it can be used in other p60 style lights... It should be very bright... I think I remember someone saying it's more like 410nm... now sure though
