Hello everyone, I have recently aquirered a 35w Sox lamp and am looking for a ballast for the thing. I remember that you can use a Fulham ballast on them but I cannot remember what model number to use. If you know, please do tell me.

Not sure on the size for 55, or even the 90W lamps. Here are the proven / confirmed Workhorse sizes for LPS lamps: WH2 = 18W WH3 = 35W WH8 = 135W, 180W

Thanks funkybulb, I tried that and it worked great. I just need to get a current meter out and check that it is within spec tonight.
