What is the best black light for beetle hunting?

What is the best possible black light to use for beetle hunting? I've seen many types and variations of black lights and they are rather expensive, so I want to know what exactly to look for.

The blacklight thatbis not coated with purple is the one you have to use in fluorescent tubes (18 watts or bigger).

*No LED, no battery running small sized blacklight, No blacklight flashlight.

Try Bioquip for UV lights. At least you'll get an idea what to look for, if you try another source.

I have two lights- an AC/DC, and a DC only light, the important thing is the bulb itself, you could just buy the bulb and ballast and make your

own. I also have 2 back up lights that are repurposed with the correct 18w bulbs. They do wear out too- always have a spare.
