Hey guys,
building a projector and wondering about my light source. I plan to use a metal halide 400 watt lamp. Have you guys found these to be strong enough to project a bright TV quality brightness? If not do you think I should get dual 400 watt bulbs? 😕
Another thing, do you guys think it is safe to put a metal halide on to a surge protector?
Thanks, in advance.
Projector so far-
I-O Data 15" flat panel Monitor (1024x768 res, 16.7 million colors)
(Possibly Dual) Metal Halide 400 watt

I have the same desktop panel you have.. Right now I'm using it on a Overhead projector and it works pretty well, but before I tried it on a overhead I built a 400w metal halide setup... I was quite disappointed in the brightness. I dont think even 2 standard mogul socket bulbs would be bright enough because the problem isnt the bulbs brightness, the problem is focusing it. Even with reduced jacket bulbs, the lights are still pretty big. Im not sure what its called, but the little quartz canister inside where the light actually comes from is too big. If there was a way to take the quart canister out of the bulb and put a spherical reflector behind it I think it could work, but the bulbs wont work with the quartz exposed to air.....so. I wish they would work, I really like the 10,000 hrs life but I have moved on to overheads...If you find a way it would be great but I wasted $100 on my MH stuff... good luck
Hey Goldmoth,
Thanks for telling me. Actually, I know that you have the same monitor as me, you gave me the idea of getting it. What do you think is a suitable light source to get proffesional quality lighting? What about a 1000 watt MH? Maybe Dual MH 100 watts...Its kind of too expensive for that but i could do that if i wanted. Thanks for your help. Another thing, is this a good lcd? Does it give you a good clean picture? Thankyou very much for your help.

Lamp
A 1000 Watt MH lamp would draw 10 AMPS! Chances are you'd have to run another line in the room just to pull enough power for it.
450watts are fine. Find a good reflector and design your box carefully.
The main problem is that people who arent burning out their lcds are so worried about heat that they place the lamp overa foot away. Buy yourself a sheet of "LOW E" glass and mount it between the lamp and lcd. You'll be able to keep the temps down and bring the lcd much closer to the light itself.
The picture will be brighter and the enclosure will be smaller.
