Bulb of Choice

[Bula]

I have Hamilton Dual Canopy (two bulbs) 400 watt hood system/ballast is a probe M59.

I need to buy new bulbs. I want to get the maxium color out of my sps. I have Hamiliton 20 k currently and have not been too happy with the bulbs. I have heard pro's and cons with XM 20 K and that running Radium is not ideal with M59 balast.

I am interested to all opinions and suggestions.

Thanks

John

You could take a look at EVC, I think they are nice

Thanks. Did you use the 20K bulbs?

I like the XM 20k it has decent PAR and develops nice pigmentation in corals. You can also look into the Ushio 20k, it's whiter than the XM and is (like the XM) designed to be run on an M59.
