Anyway I know a lot of us use the economy clamp fixtures from HQ or wal mart. The email from zoomed explans how to get a longer life out of your bulb.
I thought this info might help some one else who heats with lights.As far as getting the most life possible out of a lamp goes, minimizing handling is the first step. Lamps that get moved burn out quickly. Fingerprints and oils on the glass can also have an impact on lamp life. Also, make sure that you are using a quality ceramic socket, not a plastic "economy" lamp.
