GE 2-way 22watt pre-heat fluorescent circular bulb adapter

This is my GE 2-way 22watt pre-heat fluorescent circular bulb adapter. I got this at a re-store. It is rusted so I think who ever had this before had it outside. The 2-way option did not work when I got it. The bulb might be original because it has the old etch.

How do they do high and low?

@robertgift Look at P42STUFF's comment below.

I have one of those! Replaced the bulb/tube with a "cool white" though.

@Ethaninsf5 i wish we have more stuff on out furniture hunt. especially lamps and light bulbs!

huh. 1,500+ views but no likes or dislikes.

@TheDieselNut This most likely has a ballast with an extra inductance tap on it for underdriving the lamp. This also explains the dual light levels, as such a system would not allow for three light levels.

i like the base, loooks like the ballast base of the 3 way cfl I have next to me!

[Ethaninsf5]

very cool lights, I JUST found this exact same light, plus another GE and two uspar circline adapters, all with ORIGINAL bulbs in perfect working order... In the recycling bin! SCORE!

@TheDieselNut

You can use a transformer or rheostat to reduce the voltage which will reduce the light output, you can dim the down to about half way before they start to flicker and go out, they wont strike properly unless you have the voltage at what the fitting is designed for.

I've had better success with shorter tubes

I have two of those, but have never seen a 2 way one! I wonder how the heck you could "dim" or "reduce" a preheat's light level?

I got mine from a customer that had left bad lamps in the fixture and ruined the starter on one of them. I rigged in a starter that I gutted out of its "can" housing. Nice light!
