maybe it will improve when you get your cover glass on your hood ?? ... by the way, ALWAYS run the tempered glass cover, with high-pressure lamps, for safety ... it is true, you do lose a few lumens with the glass, but it is minimal, and I'd rather have my eyesight ... for instance, an invisible crack in a metal halide lamp, emits dangerous UV radiation, harmful to eyes and skin ... good luck :thumbsup:
