I loved my T5's when I used them. I always used ATI bulbs and had great growth and color. I swapped to LED for the power savings, $ savings on bulbs, and because I am always wanting to try new technology to see if it works (which has gotten me in hot water with my wife plenty of times.) When I first moved over to the AI's, I committed the common error of running them at to high of an intensity. The corals bleached initially, but after lowing the intensity they regained their colors. After acclimating and getting the LED's dialed in, the corals colors intensified beyond where they were under the T-5s. Growth has also been excellent. After sticking it out, I have never looked back, although at first I was worried (due to bleaching my corals.)
@ the store we have all types of light being used. Some tanks use the MH/T5 combos, other tanks have the MH/VHO, then we have several types of other LEDs. (Sunbrite, AI, maxspect, and some panoramas.)
I have had success with the Sunbrite over our 180 as well. (Wanted to note that incase someone asked about them) The only fault I have found with the sunbrite is a few LEDs burned out in one of the tubes rather quickly.
