I must say you get what u pay for as far as LEDs go we are running AI sol's and love them we use the super blues all Cree LEDs and give off a great 20k look we have a total of 7 units on several tanks gives a great spread. We run at about 65% power with lights 18" off the water. Can pick up cheap used. A lot of ppl what the newest and greatest but I love my Sol's frist pair we bought still going strong 4 years later never had a single led go out and if and when they do can pick up replacement pucks cheap.
