They suck ***. The only thing they will grow is red slime. Poor spectrum. I had 20k bulbs that were yellow.

really these 15k are really blue

Well good luck with them. They caused alot of problems in my tank in a short period of time. I switched to xm and it was obvious that the problem was the reef grow bulbs...I got mine through an online store Catalina Aquarium (wow they suck), but that's a whole other story...
