hi agian..
i managed to get the lumalux lamp to start.but i noticed some smoke coming out of the ballast(which can't be good),also the lamp won't stay on for more than 10 minutes.whats the problem with this?

I think my starter/ignitor is still good now that i've got it to light up.fyi the manufacturer of the ballast is powerlighting RU S55 150w HPS.
