help with 250w ballast

hey all im having a hard time finding a good 250 watt ballast i wanna be able to run cmh or hps so i need a magnetic ballast but i cant find one any suggetions would be nice thanx

why magnetic? try http://www.htgsupply.com they have the conversion kits pretty cheap.

I'm also in the market for a 250w magnetic ballast. I want magnetic so I can run a CMH bulb. They won't work with a digital.

I've been internet shopping and have found the 250w magnetic choices are limited. When I was shopping for a 250w ballast about two years ago (bought a Lumatek) I remember finding lots of options. Seems that's no longer the case.

hi guys i wa wondering if anyone has some schematics for building my one 600w hps balast and could give me information like what kind of transformer i need what is his specs , ignitor and stuff like that my father is in to electronics and hes helping me out but i need to know exacly what i need first thx alot hope someone can help
