I would go with the coralife T5s, thats what i bought for my 55 gallon soon to be set up low tech tank. These lights look great and sleek, as well they come with great bulbs (2x 28 watt T5s 6500 k i do believe) and are very affordable!
Thanks for the input. I have actually have two coralife NOT5 double bulbs fixtures that I am not using. They are both four feet in length. Is ok to use these and just let the extra lentgh hang off the tank?
