Galaxy ballasts are waaaay over rated. They are cap and coil (reactor). For the price, I'd look at lumateks, a 250W electronic ballast incased with leads should cost about 150CAD, And they weigh a hell of a lot less so shipping would save ya even further. I'm sure they got a site, try http://lumatek.ca maybe.

Yeah I have no experience with them. Only serving up a link in the hope of being useful...

If you don't have an luck finding a ballast, this is the way I should go.....a lot cheaper than the Ice Caps I was looking at. And with two ballasts I can control separately.....which would be a good thing.

I tried to source these ballasts for another guy on here, its and OEM thing only. Keep in ming that the ballast housing for these fixtures also has a x-former in it to step it up to 240v from 120v, so you may have to add a x-former to your list of things to get. Also the bulb size is slightly larger on 250w that the 150w so you will have to get new sockets as well.

Not sure what you mean by oem only. Lumateks are available in 120 and 240. Highhorse ballasts are not oem and also available in both voltages.

I was referring to the tridonic not the lumatek. If you dont care about using the same ballast then yes there is lots of options out there. Im not sure what mean by Highhorse i have never heard of them. If its Workhorse by Fulham that you are thinking of im pretty sure they dont make a ballast for MH and they lost their CSA and are no longer sold in Canada.

Workhorse can't handle mh, never heard that bout them? Must be farely new their ballasts were available bout a month ago at suppliers locally. Someone messed up. High horse is a new name in the game nothing to do with fulham, though they have a highhorse brand of mh ballasts as well, but only upto to 100w I believe.

Really? Crap! I was thinking that a 150 and 250 were the same bulb length. Cripes by the time I change out all the parts...I will have made a new fixture. These reflectors are small and tight....so not sure if that would work without major mods. I will have to look at this as well.

Thanks guys for your help with this. I am not sure if this mod would be practical at this point.
