This item comes in a pack of 2 star boards 495nm is Turquoise that should be used small amounts on a tank as it will quickly over power other colors if not mixed with 660nm Deep Red and 455nm Royal Blue. When mixed with the Deep Red and Royal Blue, all 3 colors will display a "White" light but still bring out fluorescent pigments found in corals. The Turuiose is going to bring out oranges and reds. This wavelength is almost a green color and is currently experimental. The idea behind this wavelength is to fill the missing gap needed to bring out certain colors like reds and oranges in a standard Neutral White + Royal Blue combo. Please note you do not need additional optics for these LEDs as they come with the optic of your choice. Best driver to use for these (6-14 LEDs) is a 40w 700mA Inventroincs driver tuned down to about 500ma using a POT. If you need help choosing a driver, feel free to contact us.
