Hi,I have two Giesemann 4 ft fixtures, the older one is the Neptune Pro, with the old style ballasts with the remote in the hood ignitors, those went out and lets just say my experience with Xenia - Phil Gilbert was not satisfactory, I ordered the parts directly from a US supplier. Kind-of strange, the ignitor is not shown in Germany, but can be found in one place in US, Russia and the UK. My other fixture is the Infiniti current model and I like it. The US needs a real distributor who will get parts and will talk with customers about problems and sevice and they would sell many more.
