Jason, I am sorry but I don't know the exact brand of those T-5HO, 4 and 6 tube fixtures. Since I have moved to Vero Beach, FL and no longer have greenhouses, those fixtures are all in storage in my equipment shed. I purchased them off the Amazon site though and don't think there was more than a single vendor that had them (but that was 3 yr. ago).
