Homemade F14T12 Fixture using a 60 watt bulb as a ballast.

Homemade F14T12 Fixture using a 60 watt bulb as a ballast.

I did an experiment to run a 14 watt fluorescent tube using an incandescent bulb as a ballast. It worked perfectly, so I made this fixture. As you might be able to tell, I made it out of a bathroom wall light, which is why there are extra holes. Painting this fixture was a nightmare. The first coat went on good, but there were a few spots that were too light, so I painted it again. The paint wrinkled after this, so I kept trying to scrape it off and repaint it. It took a few more tries before I striped it with acetone and a scraper the best I could, and gave up on the wrinkly parts of the paint job.

Let the paint dry a couple of days out in the sun before applying a 2nd coat. My experience with wrinkling is the first coat of paint is not completely dried.

Keep government out of the lighting industry.

Yes ,You can - Up to 15 watts on fluorescent, anything above that such as F20T12s probably will not work ,

I once used a GE merry midget 30 light 3 way(10 bulbs on each strand) of xmas lights. I removed 2 of the bulbs on one strand and inserted each end of a F4T5 fluorescent tube and the tube lit! Yes it is possible to use incandescent bulbs as ballasts but only up to 15 or 20 watt tubes.

At one time GE made a bulb specifically for ballasting fluorescent tubes. It was a 30 watt, 60 volt bulb, used to ballast two F14T12 bulbs in series, on a 118 volt supply. I’ve only ever seen it mentioned in 1940s lamp catalogs. Apparently it was an S11 shape.
