Universal 446-LR-TC-P Rapid Start Ballast

Universal 446-LR-TC-P Rapid Start Ballast

Click to view full size image

A few days ago, we were talking about different color labels on these Universal 4' rapid start ballasts. I just found one with a blue/yellow label. It could be blue/white, but I'm almost sure the white is faded yellow. You can see how the "Therm-O-Matic" writing is yellowed, but the Universal logo right above is white.

This ballast is also interesting because it is rated for 35 and 40 watt lamps, not 34's. It is full power, too, at .8 amps.

And it works!

I suspect this one might have originally had a green label that has discolored with age since it shares the model number with the green ones. I have a few blue Therm o Matic X ballasts but they have a different model number (446-L-SLH-TC-P) and they also say "Super Low Heat" on them.

I almost forgot -- this is from September 1977.

I suppose it could be faded green, but it sure looks blue to me!

If my memory serves me correctly, the green label Universals are normal heat, brown is low heat, grey is very low heat, and blue is super low heat.

The flow (fluo) is changing (escent). Bulb/Ballast Bans make me extremely >:-(

Are 34 watt lamps electrically similar to 35s such that they would run fine?
