I was actually wondering this as well. I would think the strike current would be lower for metal halide as opposed to mercury vapor. I was also wondering if the spectral output of the metal halide bulb would have an effect on integrator calibration. Not a huge issue since I'd run calibrations again after replacing the bulb, but it would be interesting to know.
