Insides of a bluewave ballast?

[Aquattro]

Jayson is of course correct. Perry has stated that the SA is available in their cases, but the are not recommended for the Radiums. PFO has also recently offered a M135 pulse start, which is their recommended ballast for the Radium.
The SA is used regardless as it gives a whiter look that many people, myself included, prefer. I am aware that bulb life may be shortened. I accept this as a cost of my hobby. I have seen the radiums on M135 Bluewave ballasts and don't like them. I heard the real correct ballast is a S51 HPS, although I have no idea what that looks like.
I'm not sure if PFO is still recommending the SA since offering the pulse start. Maybe someone else knows?
