New Bulb Flickering

[bnhreef]

Hey Jason,

I had this exact problem!!!!!

Last spring I bought an Icecap 250 MH ballast to run with a PFO pendant and a Hamilton 250 13K DE bulb.

The flicker started and sometimes the bulb would go out and sometimes it didn't even come back on.

J&L sent me a Geisman 250W Geismann DE MH bulb 14K.

I noticed that when seating the bulb into the sockets, quite a bit of pressure was needed. I also noticed that the end electrodes started to bend upwards. I got out a screw driver and pryed open the sockets enough to seat the bulb. I never had this problem before with some 150W DE sockets.

I then looked at the Hamilton bulb and sure enough, the little wire that is pinched in the electrode, that goes in to the glass part of the bulb, had some evidence of arcing.

I sent back the Hamilton bulb and haven't heard anything since.

This may not be your case, but this is what I experienced and it may help you.
