I haven't be on here for a while and alot has changed, could somebody tell me what the T15 and ED28 bulb types are, I asume the T15 is the narraow straight bulb and the ED28 is the big bat one which is what I have. and can the new pro reflector be ised with the big fat bulb?
thanks,
Bill

No, the pro reflector was designed to be used with the slimmer bulbs. The slimmer bulb sits right up to the edge of the reflector where the arc should be about the correct or about the nearest approximate distance to the spherical shape of the reflector.
