These are a great light for shallow reef tanks. I used this light plus another LED on a deep tank and could barely keep anything thriving yet alone living; however, on my current tank my acan has tripled, frogspawn has grown three heads, and the candy cane has doubled. It's not a bad light for the price you pay, and the control/remote are an added bonus.
I simply love the various options available allowing the user to set the timer to a number of scenarios just like Mother Nature intended. Versatile & appealing to the eye and the large LED screen sure is a plus. Bravo Current :)
