Lamps need to be replaced every 800 - 1000 hours or so for optimal viewing pleasure.

When LED's get bright enough, they should setup a Bright White LED Array that fits into a standard Blub casing, and allow all current front projector users to gain the benefits of 30,000+ hours of life.

Take out the old Lamp based module and replace with a Bright LED based module.

Make it cost 2 to 3 time as much as a standard lamp based replacment, and people will still buy it.

Just a though!!!!

Interesting. Not sure how difficult it would be but a good idea never-the-less.

Anyone else think this would be a great idea?

Is there anything that makes it impossible to do?

A plug-in replacement is probably going to be difficult, if you only consider the differences in the power supplied at the socket. Most lamps in use now require much higher voltages than LED lamps (MUCH MUCH higher in the case of Xenon). Conversely, the LED lamps would need much more current at the lower voltage. Lots of protection circuitry in the projector is also dependent on the expected voltage an current draw of the lamp of the original design. Don't even think about the projector continuing to have warranty projection if it's not done by the original manufacturer.

It's probably not impossible, but it's also not going to be particularly easy. In the end, though, it comes down to dollars and cents. Projector manufacturers are at least going to want you to purchase a new instrument to take advantage of the new technology - if and when they decide to offer it. Lamp manufacturers are not particularly motivated to spend the R&D dollars to kill their cash cow.

If it happens in the next couple of years it will probably be the result of independent experimentation.

Is there anything that makes it impossible to do?I do think it would be a great idea, but issues that come to mind are the electrical/power issues and the color issues. LED should be able to get reasonable brightness for a projector designed to compensate for their wavelengths/color temperature...but I'm not sure how practical it would be to put them in a projector designed for a traditional lamp.

I do like the idea, and it would be great if it were done.
