Ballast manufacturing/design information

Heh. If you ever figure out how to make a ballast for a 200W SLI/H lamp, let me know, they are real unobtanium

That's fine Ria, I'll keep on waiting till someone else chimes in. Mostly trying to recreate some American style F40T12 ballasts but I have plans to reverse engineer some other ballasts in the coming years. Eventually I may be able to custom make some ballasts for long forgotten lamps from scratch, but that will be when I am a much wiser man.

Hi Max,

No idea, I'm afraid, your namesake might be able to help, or Mark (Tuopeek), but other than that I'm absolutely no use (who said not surprising )

Take care,

Ria & Sammi 💖

Hello everyone,

I was wondering if anyone had any documentation/information on how to properly design and wind FL/HID ballasts? This is a subject I've become increasingly interested in as the supply of these ballasts gets smaller and smaller each day. I've started doing a little research on my own but I can't seem to find anything beyond what the circuit diagram inside a ballast is. Another collector who is also interested in the same idea is sending me a few Rapid Start FL ballasts for study but any info helps.
