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

how do you fit in a metal halide setup? what do you need to do to fit it in a OHP?

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
