**UPDATE** Limited stock - This item is being replaced by CREE XP-E2 Blue
This is Cree's color line, the XP-E, an update to the XR-E, emitting more light and using less power.
The XP-E blue should be used in combination with neutral white and royal blue over reef aquariums. Use one XP-E blue for every four XT-E royal blue or every one Luxeon M royal blue for a ~14K look. Using more than that can be detrimental, as our eyes can pick blue out much better than royal blue and the color of the light can quickly turn into a Windex blue.

I am very happy with this aquarium lighting LED. It is a great supplemental light. I love the shade of blue it provides. I can't believe what a great price! I'll definitely order here again.
