Curious as to the long term heat effects on the bulb and the reflector -- they get hot enough in use and you just packed all around yours with some insulator material that is gonna isolate all that heat in the bulb and reflector area even more.

Update this tread please with a time update please after you go through a summer heat cycle or two.

Anyone who does this with a high intensity bulb like a Sylvania Silverstar chime in on any heat effects on bulb life, etc .....

Thanks,

Me too on the Silverstar, and yes they do get pretty hot.  

Isn't some of the clip and bulb retaining stuff on the back of the reflector (where you change the bulb) made of thermoset plastic on some year models?  Thermoset might embrittle over time but it wouldn't melt on you I wouldn't think.  Same sort of stuff is used in handles on kitchen pans ....

Original Silverstars got a rep for relatively short bulb life, Sylvania had to put a durability warranty on the second generation to encourage people to buy them (still got mine, but I think like Verslagen mine has lasted longer than the promised warranty period).

Point is all the insulation stops back side cooling of the bulb and mounting parts and they will get hotter than they normally would.  

Worth a follow up post anyway after he has some time on it.
