Which is better? You have only listed one fixture???? If you are refering to wattage the 150w would be good for your current tank at only 12" deep. But if you ever want to upgrade or use it over a different tank that is deeper then you would be better off getting a 250w version. I was running my 250w over a 10" frag tank and now it is over my 40br. If you are asking about the ballasts I chose the electronic ballast so that I could run any 250w bulb I want. The HQI Mag ballasts should fire all bulbs but is specifically made to fire DE HQI bulbs. Non HQI Mag ballasts will not fire some DE bulbs depending on the M number.
I am running a 250w xm20k in mine and it is not all that blue at all. It does however bring out colors in my corals that Hami 14k, Ushio 14k, Phoenix 14k, and Iwasaki 15k bulbs did not show. These colors were there but those bulbs did not let you see them. The moment I turned on the XM20k for the first time all the corals under it showed off some very good coloring.
He's comparing the Hamilton with the above Sunlight Supply fixture and ballast.
yes, the leds are moonlights.
The LED's are night light LED's and come with the fixture itself even if you just buy the fixture by itself I believe.
