shop light-std. fl. 40W
The fluorescent fixture over my workbench is your run of the mill twin-tube 4-foot job. Only one tube lights.. The other tube will light if I rotate it "just right"... ... but it never stays lit. I've had it for years.. and it's never worked right. It was a "cheapie"...... but I figured that shouldn't matter. Apparently it does..
I believe that the problem lies in the socket-contacts. Is there a way to "tweak" them for improved continuity?
To quote Col. Frank Slade.. "I'm in the dark here..."

Save the few bucks needed...wally world NEW LED 4' shop lites are cheaper and cheaper by the week
Highly recommended to move to LED!
My problem is shop(S) all have many long 2 tube 8' fixtures... each LED replacement tube is currently $59....down from $89 but still a big wad of cash for my 16 total tubes

Roddie, just for the hell of it, check the ground(sounds familiar?).
For some reason, the old t-12 bulb fixtures act a little funny without it.
Usually the ballast grounds itself to the pan, and the cord, bx, or whatever
you use for power, grounds the pan. Maybe it shields the ballast. Had the
same problem with an 8' t-12 high output pan, and grounding took care of it.
As far as I know, the new t-8 hi efficiency pans don't rely on the ground.
Good luck.

Yes.. those are really nice.. My previous employer bought a few to mount under the shelves over our benches.. Then they decided to reduce clutter.. and removed the shelves and lamps.. A fellow employee asked what they were going to do with them.. and they said; "If you want them just take them.." So.. he got them.

The way things are going lately Doug.. that might be a good idea. Step #4 should be performed with a more "conductive" tool though. Something like a "pick" that you use to dig walnuts out of their shell. Actually... I have plenty of piano-wire scraps handy!

Interesting, I didn't know you could get LED tubes, they need no ballast also. Do they last long time like other LEDs. I replaced all my outdoor flood lighting with LED (10 bulbs) and they do the job, harsh bright light and claim 20 year life, we will see. They are plastic and don't think plastic will last that long.

Ground.... you mean like coffee-grounds? Truth be known; I don't like messing with things that I can't see.. which can kill me.. Actually; I've re-wired table-lamps.. and replaced switches in ceiling-fans.. but that's about as brave as I get.
The fixture has a 3-wire cord.. and is plugged into a grounded receptacle. Outside of that; I wouldn't know what to look for. I do have some CRC-brand dielectric grease that I thought might help, if applied to the lamps' pins..

Clean the copper contacts with some 1000 grit. Bulb pins also. If the ballast was made in China, go get a new fixture.
