thanks guys!! the lights are pretty cool. i put them down really low lastnight with all the lights off in my room, you can just about still see in with it very low and the next setting up is bright enough to see in properly. she doesn't seem bothered by them at all when theyre on.
not sure if you can get blue heat bulbs. could have a nose around i guess hehe.
the led's come in a few different colours. blue, green, white, yellow and red i believe. you could even mix them up and get two colours in one viv, that'd be sweet!
