347v PL Ballast 
Didn't know that they made em for 347v. It's around the size of a 2 lamp NPF trigger start ballast. I don't think Robertson makes these anymore though as I can't find it on their site. Seems it either has a low PF or a high loss is it draws 43VA.

Wow the ballast is bigger than the lamp it's driving. Shocked Laughing

Yeah big ballast for that small lamp. Smile

Yeah, I first thought it was a ballast for a higher wattage PL until I took a look at the label. Laughing

Usually ballasts are bigger to step up voltage but in this case it probably has to be stepped down a few hundred volts Laughing
