I ran every light system I had available to me at the time I started in this industry, HO, VHO, HID, CFL, and just now playing around LED. I have to say the easiest light was the old 175 watt pendant from Hamilton, and the 150 watt Aqua Medic HID. Nothing easier than a wall timer and replacing the bulbs every year. I have already had a Kessil 360 WE die on me in less than a year. Not sure what to use on the new tank but I also have an Aquatic Life hybrid in the box ready to pair with my Aqua Medic or two Kessils.
I do think the LEDS are to complex for most if us and plug and play is better for the industry.
