I've got a customer that I installed 60-70 4" rework cans for. Some of these are eyeballs. They have had a few bulbs "blow up". They have put in a few of the 60watt par 16 bulbs. I think that these are the ones that have been a problem. They are the only bulbs that fit in the Juno eyeballs. I think they exceed the rating of the can and trim. Would this extra heat cause this to happen to the bulbs?

They are trying to maximize the light output for the cans. Any suggestions?
