man that sucks.

1. did you try the old bulb and get the same results?

2. your new bulb.....are you sure it is designed for the position you are trying to use it in...ie: base up / base down....sideways???

3. take your light and try in diff outlets.

if it does this with the new and old bulb....ballast replacement time appears as cause.
