Galaxy ballast/Radium (1 Viewer)

Does anyone know if a Galaxy ballast will run a 250w Radium bulb properly?

The galaxy e-ballast will but it will be blue'r than if you used an M80 - HQI ballast.

I'm using the Hamilton e-ballast on the 275 watt setting to run mine and it's just fine. From what I understand, I think it has to do with the European voltage as to why the m80 is the correct ballast "technically"....

Is there any difference in output from a Galaxy or icecap?

Not sure would have to look at the specs. some e-ballasts can overdrive a bulb which in theory should reduce the blue. If you haven't already purchased ballasts for Radium look at the Hamilton M80. (PM d2mini he used them with Radium on his old tank).

*The 250 HQI and 400 HQI are European metal halide specifications which most single-ended and double-ended European lamps are built to.​

Galaxy is definitely superior. I ran radiums on icecap lumatek and Galaxy. Galaxy is the only one that consistently fired the bulb properly

I wish I could find 2 M80 ballasts. I have access to both icecap and Galaxy e-ballasts.

Since the Galaxy is a Select-a-Watt, would I use the 250 or the HQI setting for the radium?
Or is there a better bulb for the icecap ballast? That's what I have installed at the moment.

Anyone have an opinion on running Reeflux 20k on my icecap ballast?
