Nah UV light is dimmer if anything. The cool thing about them is that if you UV reactive fans, cables, etc then they appear to light up as well.
Mine came one each, and each came with a switch that controlled both.
lol, Thanks Kof, I've got a spaceship for a computer now...
I've got UV reactive cable sleeving, but that's about it, cathodes would probably look better I think, I just don't know if they'd be too bright and take over the room if you know what I mean.
I'll take a look on the site:

One of the reviews says that it comes with a switch, I'd have to find some-where to put that.
four is awfully bright. i have 4 red ones laying around. i might split those on two cases. total of 4 blue and 4 red, the blue should arrive today. i wanna see the difference with and without it in the watercooling case lolz.
