250W Giesemann light Repair?

[PaulErik]

That magnetic metal halide ballast will not work with HQI double ended lamps unfortunately. That one is rated only for single ended probe start lamps (ANSI M58). You need an ANSI M80 ballast but the bare ballasts are only made to order for lighting manufacturers. They are available fully assembled inside an enclosure. Other option is to use an electronic ballast.

Here's the solution from Coralvue. I ordered two (spare) of these since it seems harded and harder to locate ballasts.

Yes that Hamilton ballast is an assembled M80 ballast. The bare ballasts (core and coil, capacitor and ignitor kit) are typically not available anymore. Ballast choices have slimmed down even for the lighting manufacturers.

Jst wanted to thank everyone for lending a hand on this thread. I really like my Giesemann Infinity over the Ecotech Radian I have. Once I get the ballast, going back to the HQI. Always had better results with it.

Chief out...
