Hi everyone!
Well, for some reason my AB 250W 10K HQI pendant's UV glass shield shattered into a million pieces on to my live rock below the other night. It had been on for several hours and was about 10 minutes away for turning off. I've now gotten most of the glass out of the tank but can not start using the light again until I have a replacement UV shield. Where does one get a replacement? Would some glass dealers have this or do I have to contact the manufacturer?

What can one do to stop this shattering? My pendants are fairly close to the water. (It's attached to the canopy rather than suspended using cables) I'm assuming the shattering was due to water splashing up from a fish. Also a bit concerned that perhaps this inside-canopy installation of the pendants may not be very safe or may even be a fire hazard? (It was a recommendation from my LFS) Any ideas?

Also, recently one of my two pendants stopped working. It just wouldn't turn on. The ballast was making a slight humming noise but there was no light. I swapped the bulb to the other pendant (and vice-versa) and then the bulb started to light again but every now and then the pendant (that the original bulb that was not lighting was moved to) stops lighting or flickers. Any ideas? Do I simply need to replace the bulbs? Or is there an issue somehow with the ignitor in the ballast?

Thank you!
