Nope, the de halogen is smaller than a de halide and its ballast is also located inside the lamp head. You will need to take all of that stuff out and then a malide holder and reflector will barely fit inside and you will need to locate your halide ballast somewhere nearby.
I bought my halide off of ebay and it came with a bulb, holder, reflector, ballast, wiring, and uv glass. The lamp does come with a sheet of uv glass for the hlogen bulb but you would need to figure out some way of mounting it up by he bulb...
