Is it safe to put a really powerful lamp in a 2000 lumen DLP projector? Answered

I bought my Mitsubishi SD205U projector used. Eventually, the bulb is going to fail, and I want to know some stuff before it dies. I plan on buying an LED, driver, and heatsink off of Ebay, and modding the projector to use it. The best lens I can find it 60-80 degrees. A bunch of the light will go into the projector, will this damage anything? And other than the wasted light, will it hurt the image quality?

Next question, can I put a much more powerful LED in it without damaging anything?

Finally, is there anything I should know of before attempting this project?

1. Does you projector check for a faulty lamp? If so it is quite hard to transfor it for LED use as you need to fool the internal electronics.
2. The light color is very important as all filters and panels inside are matched to each other, using a lamp or LED with a slightly different spectrum will give differences in the picture as well.
3. If light goes in the projector you might want to consider a better housing for the lamp. You need to keep the lamp cool, without the proper filters and ventilation it is hard. And having a chance for dust to reach the panels due to the airflow is not good.

4. Having light is not enough, too bright might even give you a worse pic than with the old bulb in place.

Projector lamps are expensive for the material and focus.

(Ok, you pay for the brand as well...)

The light has to follow a specific path to produce a good and even picture on the wall, using a light source that doesnot match this will cause uneven lights over the picture and if the focus in the area of the panels is too sharp can overheat the panel.
