ballasts or bulbs or both?


A month ago I replaced all three of my F20T12 ballasts with new magnetic ballasts in my kitchen light fixture. I also installed 6 brand new Philips 2-foot T12 bulbs.

This was the thread in which I sought advice for that job.

For about three weeks everything worked fine with the fixture. Just this past week things started to get a little wonky. For some reason when I turn on the light switch it takes up to a few minutes before the bulbs fully illuminate ....up until then they are just very very dim.

But here's where things get interesting....in order to make them illuminate "right away" all I have to do is reach up with my hand and touch the outside of the large outer frame of my flush ceiling-mounted fixture....the lights go on instantly when I do that.

Any idea why this is happening?

Re: ballasts or bulbs or both?


Is the frame of the fixture properly grounded?

Well are they or are they not grounded?

All of a sudden, "change in temperature."

I have to double check tomorrow but I did not touch the ground wire for the fixture when replacing the three ballasts. What would temperature have to do with it?

T12? Really?

I can't believe you tossed money at T12's.

Sorry, but that is about par to running biased ply tires on your car.

Trust me I've gotten enough flack for the T12s. I didn't want this to turn into a major job where I have to call in an electrician that would charge an arm an a leg just to install a new fixture.

Like I said it worked for three weeks just perfectly. The lights were super bright. Yes, T12s.

It would have been just as easy to swap in T8's....more light for less $$

Your grounding may have been border line allowing the tube to work.
but as the weather changes it does effect floro tubes and how they start.

I know some floro's don't work reliably unless they are grounded.
yours may not be.

OK, I will double check tomorrow and take photos if necessary.

Re: ballasts or bulbs or both?


Problem solved (or so I hope) !!

It turns out the original installer (contractor? homeowner?) did not know how to ground a fixture. It was grounded to ITSELF (through a roofing nail driven through the fixture into the ceiling). Duh. See photo 1. I should have noticed this when replacing the ballasts last month.

LUCKILY I was able to locate the ground wires (see photo 2 - blurry ground wires in the background barely visible) behind the hole in which to two white wires and one red wire ran from the ceiling to the fixture's wiring. In order to access those (very short I might add) ground wires I had no choice but to use tin snips to make the round nickel-sized opening a little larger (see photo 3). Once I did that, a coat hanger and pliers allowed me to pull the ground wires through.

Once I moved the ground wire of the fixture from the roofing nail to the wire nut for the ground wire (see photo 4) and close everything up the light fixture works like it should. It may not look pretty but it works.

Re: ballasts or bulbs or both?


wow. What a complete hack job.

Those conductors need to have some type of protection where they come into the fixture.

Yeah I know it's not pretty but I know for sure (when I put the protective shield plate back in place) the conductors are not making contact with the side of the hole that was cut open. At least I have proper ground now compared to what I had before. That's gotta be worth something.

The alternative was to remove the whole fixture from the ceiling which is a two person job for starters, not to mention the extra work patching and painting the ceiling which would result from removing the fixture from a painted ceiling.

Until I renovate my kitchen in a few years, this will have to do.

I would rip those fixtures out. Throw them in the trash.
Install 5-6 inch cans. Br30 CFLs or LEDS. Or a LED module.

The tube type fluorescent bulbs, particularly the t12s are obsolete.
