LF: RSM C250 39w T5 Ballast

[chutsk10]

So, the ATI Ballasts from Reef Supplies are a suitable working replacement to the stock ballasts.

Only difference, is that the ATI are 6 wire, while the RSM are 7. You just leave out the middle wire and everything works. (The middle wire is there so if one bulb burns out of the 2, the other works. Without it, one burned out bulb makes the second not work either. Minor inconvenience).

Thanks everyone for your suggestions.

Are those ATI's also dimmable?

I bough non-dimmable ATI ballasts because the RSM C250 comes stock with non-dimmable ballasts.

Reef Supplies does have dimmable ATI ballasts but I am not sure if or how that would work.
