Exploding CFL's are not something that happens regularly. Your bulb should just go dark.

Also, down lights? I know they produce ALOT of heat, but my house is pretty much run by them :P and they are easy to get my hands on for free. So is it possible to grow with downlights? Whats the deal?

Cheers
What's a 'downlight'? I've never heard of them.
