the lights themselves are great. Mobius, on the other hand... it's single handedly made me want to swap over from ecotech to another brand. it's embarrassing when people come to admire the tank, and you try to show them the amazing colors under blues only for half of the lights to turn off after 6 minutesLove your built...Yes I agree Radions. I have 4 on my 300, XR30blues... I added 3 Kessil A360x in between each radion and I love the shimmer and extra Blue I can get. I have the Kessils at far blue come on at 7am go off at 9pm (max50%) the Radions come on at 10 go off at 7. I also use the kessil to modify program when we have people over so that the tank is not dark and so I do not have to mess with the radion program...
