Review on Designers Edge 100 Watt Medium Halide by Dorvin Hawk

I am an old invalid. After waiting a few months for someone to climb the stairs to get to the metal halide light fitting, the installer determined that this light bulb, which has a partial protrusion on a metal screw, would not be able to handle the 1500 - Watt light bulb that came with the kit. original attachment. And now there's no turning back. Very disappointing. A warning about the different categories of lamps available for luminaries would be nice. A rating of zero would be more appropriate.
