I cant find a bake around anywhere this might be an alternative to the bake a round, what retail stores doyou think carry glass candle shades?

bake-a-round's aren't made anymore - gotta e-bay it. Yes that 1st one will work, though not for 250w+ I'd think cause of the diameter, that goes for all of them.

Well the diameter for the first one is 5" and the other have a diameter of
5 1/4", the pyrex bake around has a diameter of 3 3/4" diameter, see here, http://www.rubylane.com/shops/charmingandcheap/item/7950


these glass candle shades have a biger diameter to allow more air flow.

that first one looks like a winner. as long as your light is less then 10 inches in length and 5 inches in every other direction.
you could easily tape or zip tie some flexible hose over the ends of that glass shade.

A single glass candle shade should fit most bulbs except for 1000watt bulbs. You could probally join two glass candle shades together with some ducting tube in the middle and connect both to form a giant 28" cooling tube. Most 1000watt bulbs are 3" in diameter, which should fit cause these glass candle shades have a 5" diameter.
