I'm looking to get a new 20K 150 watt double ended bulb for my 50 gallon reef tank. The bulb that i have on it right now is a 10K and it is just too yellow even with my actinics running with it. Anyway, my question is does anybody know a really good brand/deal of a 20K 150 watt double ended bulb out there? Or are they all pretty much the same? I noticed some brands are made in germany and others in japan, so i don't know which country knows their metal halide better. I was thinking about getting an XM or something, any feedback or knowledge/experience on these bulbs would help, Thanks alot.
