PL-13 and 14/15/20 are lamp/ballast compatible

PL-13 and 14/15/20 are lamp/ballast compatible

I decided out of boredom to hook my 1980s GTE/Sylvania PL-13 adapter up to my Kill-A-Watt meter and see how much current it fed. I was surprised to see that it used 0.27A, as I had forgotten that the 13 watt PL is an oddball lamp that requires much more current than the 5, 7, and 9 watt units (which, to my knowledge, require current similar to a 4, 6, or 8 watt T5 lamp). I sprung an idea, and rigged one of my small T12 lamps to the adapter to see how it ran. It turns out that a PL-13 ballast is a perfect substitute for a 14/15/20 ballast. Likewise, a PL-13 should be perfectly happy running on a 14/15/20 ballast. Here you see my 1987 GE F14T12/D lamp running on the adapter. I've tested all the lamp types in question on the adapter, and these are the results:

PL-13: 0.27A, lamp power 15.5W
F14T12: 0.32A, lamp power 12.0W
F15T12: 0.30A, lamp power 14.0W
F15T8: 0.26A, lamp power 13.0W
F20T12: 0.26A, lamp power 13.5W

This could open doors for home-made T12 screw-in adapters, like those that were made in the 1940s, since the ballast and screw base are already made up. Now, something I would be interested to see, is how well a 4-pin PL-13 runs on a 14/15/20 rapid start ballast.

I have some ballasts that are rated for both the 14-15-20 watt linear lamps as well as the PL-13 lamps. You could easily substitute one for the other.

Some members here have made fluorescent adapters ranging from a 4 watter all the way to a 40!watter (although the latter needs extra mounting hooks).

Funny thing is, when the PL13 lamps (without the starter built in) use an external starter, they use a FS4, same as the 30-40 watt tubes. Look on some newer starters and you will see "for 13, 30 and 40 watt lamps".

Thanks guys. Weird how the PL-13 works with the FS-4? Mine has an arc voltage of 65V, so I would think it should be fine to use with an FS-2... Evidently there's something other than arc voltage that determines what starter will work with what lamp, because if it was based solely on arc voltage, a single starter would fit 4, 5, 6, 7, 8, 9, 13, 14, 15, 20, and 22 watt lamps. Maybe current-handling ability?

Edit: Oh wait, that's what the FS-22 is for!

Some of the European starters are good for 4-65 watt tubes. I think those may be electronic though.

Our common glow-starters are:
4-22W series (120V),
4-65W single (240V, previously rated at 4-80W) for lamps up to 5ft T8/T12
and 70W-125W for 6ft-8ft lamps

Wel those fS4 starter only reason it have 13 wAtts cause of use of auto transformer ballast for F13T5 lamps

No LED gadgets, spins too slowly.  Gotta  love preheat and MV. let the lights keep my meter spinning.

Oh yeah, I forgot about the F13T5.

I always thought the appropriate starter was a function of the ballast OCV with the exception of two lamps in series on 230-240 volts.
