This is a Philips F40T12 lamp that is not being used anymore. Unfortunately, my stubborn father won't let me have it. In his words, "No, you may not have the bulb. End of discussion!"

UPDATE: He may let me have it.

Do you guys know if 2 F20T12s in series will work with an F40T12 rapid start ballast, and would there need to be any cathode heating in the middle? I will have to resort to this because my dad won't let me have the F40 lamp.

@Fluorescent05:
2xF20's in series on RS will not work unless you have cathode heating in the middle.
It will work on preheat though. (infact is commonly done that way in the UK)

Forget the lights..just give me a good lightning storm & tornado to go watch...

Too bad he won't let you have that. It's an oldie from March 1989.

@streetlight98, we negotiated so I might be able to have it. By the way, thank you for dating it.

@xmaslightguy, what should I use to heat the cathodes?

I love the color of pre-EPACT cool white. Post-EPACT cool white looks yucky in my opinion. This lamp is pre-EPACT and has that beautiful crisp cool white color and is VERY bright for an F40T12.

The lamp pictured above is cool white, but seems to have the same color as today's daylight, maybe with not as much blue?

This lamp is one of the lamps that was used in an (I'm guessing 3 lamp?) fixture that used to be in the room the lamp is pictured in. My grandfather says he remembers breaking the other 2 lamps There is a duct tape mark on the end probably because he taped the 3 lamps together before he broke the other two. The fixture was a fake-wood light box with a cracked ice-style diffuser and fake wooden panes on it and was rapid start. It was installed in 1988 when they aded onto their house, but has since been replaced with a 6 lamp 50 watt (each lamp) GU10 track light. I still remember that fluorescent fixture from when I was really little, and it had the EXACT same color as the lamp pictured above.

I believe all you need is a standard (AC) low-voltage transformer - an actual transformer, not one of those electronic things.
I don't remember what voltage/current is needed though.

Themaritimegirl used a 9 volt battery for one of her experiments, would that be OK? I don't have a low voltage transformer.

9v would be used for an f20 and i think 3.8v or thereabouts is what the f40 would use.

My experiment with 2 F20s worked and has a nice startup flicker.

What ballast did you use to run the 2 F20s

Advance R-140-1-TP (with middle cathode heating by a 9 volt battery heating both middle cathodes and wired like a series RS circuit (with the yellows hooked up to the + and - of the battery))

These were generic lamps sold at Home Depot. The ones without electrode guards would start to blacken days after installation.

Preheat and T-12 fluorescents forever! Down with LED's and instant start T-8 fluorescents.

I can tell it's Philips made because there are stamps in the end caps to help align the lamp.

Also the date code and "O" (factory symbol I think) are Philips things.

Would the yellow wire output on a 2 lamp LPF F20T12 trigger start ballast work to heat the cathodes? (without anything blowing up)
