Hi, these are available again. Please read important new information: Upon testing these for shipment to the new buyer, I discovered that channel 3 in both lights is not working correctly. Some of the diodes on that channel are burnt out or dimming. Channel 3 includes the UV spectrum, so IME/IMO not very useful for corals. Regardless, the rest of the lights work fine, but since this channel is malfunctioning, I am reducing the asking price significantly.
These still work great for corals and I was using them on my tank up until a few weeks ago. Orphek sells conversion kits for these that can replace the entire LED board with their newest model "Icon" and you would end up with essentially a new set of lights. They also allow you to upgrade the control board which would allow for use of their newer control app.
