blue led's do have a slight uv effect but pale in comparisaon to actual uv lighting [it a blacklight you've played with them? had one before, right?]
el=electro luminescence[spelling?] pretty glowing wire to wrap stuff with.
cold cathode lighting is what you seek i believe
uv lighting <--- just an example the reveiws dint look to good for this particular product, but they're newegg reveiws which are an entirely different lesson. [any idiot can write one even if they dont own it. i've seen products with excellent pro reveiws rated down to one egg by fanboi's and idiots. so take reveiws with grain of salt and make up your own mind. most reveiwers there are noobs that have a "high technical understanding"-umm yeah unless you design and make them oyur understanding is above average at best.] [/rant] 8O
yes it does light up like that in the dark, but just like a blacklight, it fades almost completely when you turn the regular lights in the room on, or in daylight.
hope that helps... anyone want to correct me feel free...
