I just received a LEC 315w bulb that I ordered. I opened it up and there are two scratches on it. The manufacturers safety warnings say not to use it. Is it safe to use or should I request a refund?
No good, me thinks. Round cylinders can take a lot of expansion related stress. Glass is tough, but you just need score a sheet, for it to know where to break. It's just that foot in the door. The stress riser.
