>>I'm installing porcelain light fixtures into some new display cages and had a question. The electrical box which I have fitted into the cage drops the whole fixture about two inches or so and is a real eye sore. I want the smallest profile, if I put the porcelain into direct contact with the wood, am I asking for a fire?
I have done this before and no the ceramic usually doesn't get hott enough to worry about starting a fire. Now if you are using a MVB then it could be a problem.
But if you are still woried you can always use a low profile electrical box they are app. 3/4" tall but I am not sure. If that is still not enough you could cut out a hole and subset the box in the hole.
Like I said I don't think you will have to worry about a common buld starting a fire due to heat its the electric part that is to worry about. More fires happen because of faulty wiring then because the bulb socket got to hot. The other problem with surface mounting just the ceramic socket is that ther is little or no room behind these for wiring.
>>At what temp will a bulb become dangerous?
If it burns you than it will burn them!
>>Oh, anybody have some good bulb guard designs to share?
Do a thread search on that topic there was a thread not to long ago on that very topic with some excellent pics. If you come up short I am sure somebody will post a new one for ya.
Good Luck
