I've read that our magnetic ballasts under drive most lamps. So I have been doing some searching and found this site. Overdriving Lamps And Ballast - Lumenlab Quote "The M59 outputs 135V at 3.2A. Almost all of them come with a 24uf cap. If the cap on you ballast is 24uf then adding a 2uf cap will increase the power by about 50 watts and about 50 more watts for each 2uf of cap. (more like 50 watts -5 for each 2uf)" What do you guys think?
