Quite interesting though the key to a good projector bulb is it’s ability to produce a natural white light. Overhead projectors aren’t much on quality and usually just throw uneven dingy yellow shades and a nice big hot spot in the center. While this is quite interesting in terms of getting an otherwise junk pj back up and running for cheap money, I’d be interesting in seeing a slightly higher quality solution where the bulb has good color accuracy and no hot-spots, even at $40 or $50 a DIY bulb with white levels and even light output would be a fantastic alternative to the $400-$600 replacement bulb.

I’ve done this before, and I’ll tell you the result was disappointing to say the least. I used a standard 240 volt (UK) spotlight bulb, but the problem is unless the light coming out of the bulb is exactly parallel, it won’t pass all the way through the projector, so since my bulbs “viewing angle” was ~30 degrees I estimate only about a quarter of the light output of the bulb got to the LCD’s, and even less to the screen. Interestingly, color was off to start with, but a few color profiles soon sorted that (adobe gamma utility etc.), and hotspots aren’t a problem because the projector had a lens that looked like frosted glass, the purpose to evenly spread light across the screen.

Very good colour rendering due to high temp burn and inexpensive into the bargain. Uh uh, no you can’t.

You have a ballast which has an initial voltage of over 5KV going through it. It is only once the lamp is lit it drops to about 70-90V. What you have to understand is the projector bulbs do not have a filament like that of filament type bulbs. Instead they have an air gap which is where the arc forms and kept lit by aplying continous voltage.

I’ve used a bulb from (thanks to the above anonymous) and it is really quite simple to replace. On top it works out cheaper when you compare it with price per hour. These bulbs last 2000 hours compared to the 200 hour life of the osram. Besides, X1 is a DLP projector, the light source is not point on the osram so it will be difficult to get all the light inside the light tunnel.
