i can get hold of projects for a cheap price but for only 2000lumens. can i increase the ammount of lumens on that projector by changing the bulb or do i need to look for another projector with 4000lumens??
most of the time no .. other bulbs wont worth with other projectors now you could RETRO fit them by mounting a metal halide setup in side of it ....but after all that work .. you may as well just build your own box

that is a OHP that was retro fit with a HQI metal halide setup ... you just have to gut the OHP and setup the MH inside ..... its not that hard but you will have alot of light leaks .. unless you do sorta what he did there with the plywood ... but after all that you could just build a box ...
witch means you really dont even need the OHP .. unless you wanna try and use the fresnel and projection lens

well growlights dont have the right color temperture for a projector so you can rule those out as for the ballast im not sure ..... but i know one thing and that is i dont like buying that kind of thing used but thats just me
weel the ballst is new, thats what i have been told by the seller. i am still looking for a decent 4000W halide bulb. if anyone can find a good one on ebay.co.uk i would appreciate your help.
i cant tell just from looking at the bulb .. you need to find it someplace where they have the specs on the bulb .. the main spec would be the color temperture and arc length would be good to
