I've been reading what you all have to say for a few weeks now, and i'm a little concerned about the effects that different lights have on the sensor bar. next to my tv, i have a 4 foot vivarium for my tortoise, and inside this vivarium is a 3 foot ultra violet bulb. i dont wanna set up my Wii and make my tortoise glow!!! JUST KIDDING. But i'm curiouse about weather i'll have to rearrange my living room. What d'you think?
