I've finally found a great source for replacement projector lamps that's
CHEAP!
I've been trying for the past few years to find a source for just the bulbs, not the entire assemblies. I've always thought is was ridiculous to spend $400 to $600 on a lamp when I rarely get more than 1,000 out of a lamp in calibration. Especially when most of the actual lamps are made buy Osram/Philips and have the stock number printed on the side of the lamp.
Well, I finally found my Mecca of projector lamps.

My current projector is an Optoma H78DC3. The replacement lamp assemblies run abour $370 plus shipping from any of the discount on-line sources. It runs about $400 from Optoma.
Interlight has the replacement bulb for just
$199.50
Most lamp assemblies will come apart with just a few screws. You just have to make sure you do not touch the new bulb ANYWHERE with your fingers. The slight amount of oils from your fingerprint can cause a lamp to explode. Wear disposable glove and wipe down the exterior of the new lamp glass reflector with 90% isopropyl alcohol to be safe. DO NOT TOUCH THE INSIDE OF THE REFLECTOR GLASS OR THE LIGHT STUCTURE INSIDE!
At these prices I won't think twice about throwing away a lamp because it won't calibrate properly. And it should only take a few minutes to replace a bulb in the assembly.
I received my lamp yesterday via 2nd Day Air for just an additional $24 to Florida. Installed last night and will preform a full calibration over the weekend. Now that I know the comapny is legit. I'm going to order a spare bulb next week.
