Hello, couldn't see a more appropriate place for this... I bought ceramic heat lamp fittings, supposedly made for the purpose. Since October, we have gone through quite a few globes - not sure if that's normal. A month or so ago when the last one blew, I found the globe had actually come loose in it's housing & I had to remove the whole fitting & smash the glass out, in order to get the screw end out, to replace the globe! But I found the plastic sleeve around the ceramic was brown & crumbly(cooked!) and when I had to disconnect the wires, the plastic coating of the wires was also cooked! So... thought maybe a faulty globe. Threw away the fitting & replaced it with a ceramic with metal 'sleeve' bit. But now the other light has blown & I went to replace the globe & found exact same thing - plastic sleeve has some brown crumbly bits, plastic on wires cooked where they connect to ceramic, globe has come loose of it's housing... This looks a wee bit dangerous to me - like it is very close to starting a fire! I'm not replacing the second globe, but need some advice on what comprises & where to get SAFE fittings??
