Can only speak for myself and I know you've seen my tank. I had the Marineland DB LED
fixture and when I went to my 75g I tossed it and went with T5 HO
's if that helps. I felt the LED
didn't do justice to my tank, now with the T5 High Outputs I think it looks killer!
But in the end it's gonna be preference. What I did was tried them both and a few others and just returned all the ones I didn't like. I went through about 4 different fixtures. I just asked about the return policy before hand. And the end result is me being happy
Good luck brother.
You could always try a double bulb fixture and add a different color. I personally like the daylight with the actinic light at the same time.
