Yesterday installed seven recessed lights. halo 4"... after i put the bulbs in i went down and flipped the breaker on, i found that all bulbs but one worked. So, naturally i switched out a bulb and found the lamp worked. So I at first figured it was a bad bulb... the lights were left on all night on a low dim. today I turned the lights on for about 5 minutes and another bulb blew.. same can.. I also noticed an orange glow coming from the dimmer. 15 amp circuit. 14&12 AWG wire. The dimmer is rated for 500 watts. the lights are rated for 50 watt max PAR 20. And yes, I used a dimmer capatable bulb.
:confused:Any clues to whats going on?

Maybe just bad luck. If you blow a third and a fourth and a fifth bulb in the same can, post back (although we probably still won't know).

I think i've figured it out. inside the can there is an IC to keep it from overheating. I think that it might just be a bad IC. So im just going to switch out the fixture.
thanks though.

Yes, a definite possibility. It's a simple enough test to move the bulb to a different fixture to see if it really went bad or not. Normally when the thermal protect turns off the bulb, it turns it back on again when the unit cools back down.
Note that this thermal protect is unrelated to the "IC" (Insulation Contact) rating. Both IC and non-IC rated cans have thermal protection devices. If, by "IC", you meant Integrated Circuit, then you are giving this simple device too grand of a status.
