Here is the metal halide lamp lit up. And a close shot, as you can tell it's one of those weird shape lamps. Not sure why they are shaped this way but I thought I'd get a shot of the lamp.
It's GE's new envelope to replace their ED28 shape for the mogul base 175 and 250W MH lamps. GE did this to save glass. It's a unique shape IMO but these lamps are very very junky and tend to go "boom" prematurely.
