I would be worried about heat in such a light. Throw would not be that great, as it's not a short arc metal halide (before you flame me, there ARE short arc metal halides made by Philips). Also the MSD250 puts out roughly 1,120 btu/hr of heat +/- 10%.Would it be possible to mod an existing light, say a thor, into taking a Phillips MSD 250 theatrical short arc bulb? Any ideas on this? Maybe it's not feasible, but can it be done?
