Default Question about a black light

hi all.

i know somewhere on this site (maybe more than once) there has been a post where to buy a black light. i searched thru multiple threads and couldn't find any of the posts.

can someone give me a heads up where i can buy a portable (battery operated) black light. i will be doing some sampling out in death valley and wouldn't mind checking around at night to see what i can see.

thanks.

scorps are what i am hoping to see.

but my understanding is that black lights emit w/in the UVA spectrum (around 370nm)...shouldn't UV lights work then?

Honestly, I am not sure. I have only heard of the Black light, and have only used the black light. We tried the little flash light ones, and they did not put off enough light to fully see around you. We use a long black light ( you can pick them up at Walmart), then we just use extension cords, so we can fully get around the house or Complex.

yeah....i have a long tube, corded one. but i will be out in the field....miles upon miles upon miles from an electrical outlet, so i am on a quest for a battery operated one.

not really a necessity, but would be kinda fun to have a look around (esp. since 2 of the 4 people going are scorp-o-phobes )

Yeah, I would think they don't want to really see what is out there!

UV is black light BugBully. The way they work is they simply use UV leds to illuminate. The purpose for the UV flashlight is for chasing scorpions. Here is a link to the little combo flashlight...think I may buy one of these...

Black Light and Flashlight combination handheld portable 2 in 1 dual mode blacklight for locating scorpions and pet urine stains

The physics involves receiving radiation in the UV which is shifted by a photo chemcal reaction to visible light. Works much like a flourescent bulb. You cannot see the UV radiation so you only see the resulting flourescence.
