We try to keep up with what's going on in the hobby. If you are not aware, recently there has been information and conversations going on about blue light and is it effecting our eyesight. Cree (manufacturer) has done a study and put out information concerning their blue Leds. Without going into more detail, here's a few screenshots of a conversation by Steve Tyree (with Sanjay's response) I hope I attached them in order. My apology if I didn't. To get more information, attend the Midwest Aquatic Convention in Naperville, Illinois November 10th & 11th! Presentations and a speaker panel will be discussing this and other lighting information. We will be there!! Stop by our booth, say Hi and buy your corals from us!
