Hi, not hindered by any knowledge of LCD Projectors I would like to share the following info.
I came accross this web site
http://www.fliklite.co.uk/home.html
These people produce a powerfull light torch with an output of 24.000 cancles (No idea how much in Lumen) produced by LED's not bulbs!!!
The point is that the torch uses 4 LED's to produce the light and generates almost no heat while putting out a very clean white light.
Somehow I believe that dealin gwith the heat, the bulb and fan make projectors complex and difficult to build. Possibly the use of these LED's in a back light arrangement will produce the kind of light output a projector needs at a much lower cost and brighter output.
These LED's are guaranteed at 50.000 hours burning time (That is if you can speak of burning with a LED)
Any comments?

It may work... but I don't think so, feel free to try it.. 😀 your money, not mine... Also, I thought about those compact fluro tubes. A 13watt fluro is equal like a 75watt bulb, so for equal to a 500watt bulb, you need 7 or 8 bulbs.... and that would draw about 90-100watts...
Luxeon LEDs
Have you thought of trying the Luxeon Star LED? It puts out A LOT of light for a single LED. You would need to condense that light before it hits the LCD panel, using a condenser lens but it might be bright enough to work. I had used a 2" panel from a pocket TV along with a single bright white LED and a condenser, and it was ALMOST bright enough for a 40" image. The Luxeon is supposed to be 10x brighter than the brightest standard white LED. Just a thought.
