I'm looking for a UV light, mostly for fun but also to detect bodily fluids (of my cats :) ), bugs, scorpions, money detection etc.
I think I want a 365nm, but if it's not the best wavelength for the task, do tell.
I want it to be relatively cheap (not more than 20$).
On eBay I found this one http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=370472749835&ssPageName=STRK:MEWAX:IT#ht_3679wt_1139 with some fun colorful rocks included.
Is it different from the 10 for 15$ at Kaidomain? http://www.kaidomain.com/ProductDetails.aspx?ProductId=2102
I'm also thinking about a drop-in for Ultrafire WF-502b http://www.tmart.com/UltraFire-WF502B-3W-210-Lumens-CREE-Q5-5-Mode-LED-Flashlight-with-Battery_p100633.html . I haven't found any that claim 365nm, but found some general UV like http://www.kaidomain.com/ProductDetails.aspx?ProductId=10572 . Will it fit? Any guesses as to the wavelength?
Also, if there are any 365nm 5mm LEDs I could maybe solder them instead of the regular LEDs of a 9-LED flashlight I have (something like http://cgi.ebay.com/NEW-9-LED-Mini-Gray-Ultra-Bright-Torch-Flashlights-/400184435223?pt=AU_Sport_Camping_Hiking_Lamps_Torches&hash=item5d2cd9e217 )
Also, do I need protective glasses / skin protection for using the keychain LEDs? For the dropin? Any recommendations for such protections?
Thanks.
