I love mine, only have just the T5s though. I have had it for a month and my SPS love it. I am seeing a lot of good responses, as for color spectrum I don't know what you are aiming for but I like mine around 20k, 6 blues, 1 white and 1 purple gives me a very nice blue spectrum. The light is very uniform and it looks great from far away, no shimmer though :P Those Leds are going pack a nice punch

Did you get a 4 or 8 bulb.
