Any one using the Radium bulbs have any problems. I have been using one for
30 days with nothing but trouble. When I switch on the ballst, I must
unscrew the bulb slighty to get the thing to fire off. Once it comes on it
works fine.

The bulb is installed in a NIB blue wave ballast and reflector. I have
changed out the mogul to one of higher quailty but still have the same
problem. I have also soldered all contections. not sure what to do now. The
ignighter may be next.
