Has anyone tried a Fluorex bulb with an LCD projector project?
I'm about to embark on building a projector and want to use 2 Fluorex bulbs since they run very cool and produce 500W each.
Seems this should work with a combined 1000W of light.
Anyone with experience using these?

I don't know these bulbs, BUT
No one has managed to use 2 or more bulbs of any type.
500W bulbs get VERY hot, 2 of them will start a fire.

Flourex bulbs actually use a lot less power than 500w, it's something like 60w, but their light outout is that of a 500w bulb. Zark, one of the first DIYers used two in his small-panel projector.The probem is, they're not point source so you loose a lot of the light. Alright for projectors that use a 4" or 5" panel, but not for LCD monitors, from what I understand.
500W lamp uses 500w. otherwise it will be called "500w equivalent"
If I remember correctly, someone in this forum tried it and failed. His post might be found in one of those two perminent thread about 10 months ago.

Uh... if these are the flourex bulbs that everyone else has tried, then they are 500w equivalent. From the Lights of America website(only manufacturere I know of), the 500w Equivalent Flourex worklight uses 65w of power. I doubt there's a flourescent bulb in existence that actually uses 500w of power. And like I said, people have used them succesfully for small LCD projectors, but not for 15" LCDs.
Fluorex and Small OHPs
Thank you all for the great replies to my query.
My main reason for using these bulbs was to reduce the amount of heat. I realize these are 500W equivalent. I have 20W fluoresant bulbs in my lamps in the living room. These are advertised as 60W equivalent and I'm very pleased with their output.
I think the light point source problem could be overcome by placing a reflector behind them then a focusing lens to a fresnel for even dispersion across the LCD.
Unfortunately for me to try this bulb, I'll have to either Drive into Watertwon NY and check at Wallmart or Lowes for them.
I suppose I could go with 300W Halogen. I just would like to get away from the heat so going this route, I'll have to put in some large fans.
Here's a question:
I've seen the new flat style OHPs. What type of bulb are they using in them? Seems they don't use any fans for cooling or if they do they are very small. Anyone know?
It's great to have a forum like this. Thanks to all for your opinions.
