Product Description

**UPDATE** In stock and ready to ship

660nm is a deep red that should be used small amounts on a tank as it will quickly over power other colors.  If mixed with our 495nm Turquoise and 455nm Royal Blue, reds can be used in more quantities because the overall color of the LEDs becomes white.

These are the main LEDs used in ATS builds (Algae turf scrubber).  Our premium grade Deep Reds produce 560mW @ 700mA


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 (8-22 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.

  • Yes, they are RED

    by David – 4th Feb 2014

    Used these with the Turquose. Nice color. Added them to my Royal Blu/Cool White to encourage SPS growth. I am seeing better growth (More upwards than outwards) On a 10 gal tank I use 4 of these paired with the Turquoise with 90 degree lens at about 11 inches off the water along with 9 Royal blue and 6 Cool white 3w leds with 80 degree optics, and two of the 3-up ocean whites.
