Yes, those are the ones I use. They're cheap, good, and allow me to daisy chain more lights. I use 2 blue leds on my 10 gallon and 20 gallon long. My 125 gallon has built in leds in the Coralife 72" light strip. I'm thinking of adding 3 blue leds on my 29 gallon, but since it's an open top, I have to way of mounting it directly on top, unless I use a short glass top to place the leds on top.
