I had one of those cheap ebay bulbs do that. I guess it could be dirty contacts too.. Sounds like your bulb has been in there a while.If I remember correctly on mine you kind of have to push the bulb in one one end and pull the other end out simultaneously

Yeah its an eBay bulb, and it's getting old. I'll give that a try! I'm used to the spring design where you just press one end and it pops out.

Any ideas on where the glass bead should be on a 70w hqi bulb? It was facing down when I got it but most people seem to put it up? Does it make a difference?

No clue, doesn't much matter if you can't get the bulb out you should maybe start looking for a replacement. Good luck,, 70w bulbs in a known brand are hard to come by. I have prolly 6 different ones and can't say I liked any other than the ushio one.

Yup I've got a ushio on order! Liked the look of it the best and they aren't to bad for cost either. I might try another ebay bulb just for the heck of it. They only run 15 bucks so it's worth a try, or at least as a backup. I guess I have an noisy reef tank for another week until the bulb gets here!

Popular myth. Sanjay did an article on nipple orientation years back, it didn't matter.

Yeah I read that article and it was pretty informative. I just took the bulb out and cleaned it, and now it's quite, so I guess it was just a piece of dirt!
