Hi my name is Daniel if anyone knows how to get a GE HMAA Or even a Holophane HMSC Lmk. I live in Columbus Ohio.

Here is a 400watt HPS GE HMMA https://www.ebay.com/itm/123856511982

Won't work since it's 480V only.

Could swap the ballast out I suppose. This OEM GE kit should fit perfectly or you can retrofit a 3rd party ballast in.

I’ll definitely check it out. Though I think it’s pickup only but will try to get one sometime this year
