Which lights?
I tried the UFOs and sold them to get rid of them. I just did not like the way they made the tank look no matter what settings I tried.
The K7s on the other hand, even if I won the lottery, I would still use them. I would, however, pay someone to figure out an add on box to allow pc or phone control. No, not more features, just point and click setup without the dial. As it is, I set them to manual to the spectrum I want then use an alexa outlet to turn them on and off. It works out very well.
I have grown everything from plants in a 12 foot long tank to frags to a refugium. They just plain work and, dollar for dollar, you can't beat them.
My 240 reef has 5 of them and not one channel runs above 80%. Coverage is fantastic!
@Manose and I tested them against many lights and still stick with them.
