Re: Metal Halide bulb question.
Hopefully it was fine, when I first started using HID lights I was scared of fires too, I'm over it now though.
A lot of the newer bulbs (Hortilux I know, others I imagine) uses special ink on their bulbs that will discolor after a few hours of use. Of course that only helps you if you have a known unused bulb to compare it to.
