MH Bulbs are a pain

[viperfish]

I just installed new 250W bulbs and broke the flat ceramic piece on the bottom (where you would put your thumb to push them in) I hope this doesn't affect the performance at all. I think the contacts are too tight in my fixture, I broke the ceramic on the old bulb taking it out so of course I had to fish the pieces out of the tank. What a pain in the #@$%! Anyone broke a piece of the ceramic in their bulb? Any idea if this will have any negative effect? The contacts weren't damaged at all.
