Here is a DIY projector I”m making for a friend. (I get to work out the kinks before mine 
I’m using a 15.6in LCD monitor from Wal-mart, the monitor it self is kinda crapy but it makes a decent projector, BTW get site to store it cost me $98 even tho I could order it from there site for $79 and wait a week…. www.walmart.com I was planing to use a 1920×1200 screen but the controller board apparently got lost in the mail … so that’s why I used the Wal-mart LCD in a pinch. The LED light source is the most important thing here considering it’s about $290 for the more common metal halide. This was about $80 for the LED and less then $20 for the 2 Laptop power bricks for the 30V needed. this is more efficient drawing less then 100 watts for the whole thing. But…. it’s not as bright, tho if you see the LED not in there it’s crazy bright. Guess that means 2 or 3 for mine.

@prestono99 i have 50W and is bright enough
yay running man amv
I’m using it with a 15. 4″ LCD in the video but a 150″ screen is really pushing it. The projector in the video it’s currently set up on a screen about 70″ (diagonal) and I’d say it’s good but easily washes out with ambient light.
so will a 100w LED work fine for a 15” lcd and 150” projection size?
i have 100 videos of diferent diy projectors

Sorry I can’t really say much about the metal halide bulbs othere then they’re really hot. I’m using a 100 watt LED for the projector I made.
What wattage is your metal halide bulb? I think i’m going to need one for my tiny 3. 5″ lcd projector i’m building. I’m not sure if a metal halide is the best choice for my small scale projector. Would a 150w halogen be bright enough? Do you have any advice?
