The two photos above show the same tank under two different Illumagic lighting products. The tank owner is Matt Green, who is an experienced reef keeper from Australia who has some beautiful LPS corals in his 2ft tank. He had a Blaze series, M-60S on his tank (left photo), and he was trying to compare the ComboRay with the Blaze to see what difference a ComboRay unit can bring to his tank. The right photo shows the same tank under a ComboRay CR-60 unit. The LEDs installed from left end to right end are UV/Violet/Royal blue/UV/Cool white/Blue/Royal blue/Cool white/UV/Royal blue/Violet/Blue. As one can see from the two photos, the color tones of the tank are quite different. For that under a M-60S unit, the tank is more bright and the red color seems to be more pronounced. For that under the CR-60 unit with those LEDs installed, due to the dominant wavelengths ranging from 400nm-500nm, the light demonstrated a significant actinic effect on the corals and thus brought out more details. The condition of the corals under two lights all look good. It is not easy to judge which one is better. For those LPS corals, we believe that they will survive and grow for a long time under the CR-60. In our opinion, the completeness of light spectrum plays a more important role than the brightness.
