I have a 150 Hex tank (30 in. deep) What would be the best LED to look at? I have T12s (8 of them driven by icecap 660) It looks good but, now and am thinking of changing to LEDs.
Lots of options as well as opinions. I really like the look of 2 Cree Royal Blue Bin D316 for every Cree Q5 Cool White. If you go with dimmable drivers you will be able to adjust your colour to meet your taste. I would look at either the Cree XR-E or XP-E.
