Would conversion to heat really be included in the efficiency of the lamp itself? I would have to agree with you that number 3 would be the issue, although I don't think this is why people get parabolic reflectors. Reflectors solve more than just the issue of restrike. Just because the light coming from the lamp is not being absorbed back into the lamp does not mean it is being directed at plants and being used.
