I have been using the Orphek Atlantik Icon for 6 months since my initial review. During that time, the 120 gallon test system had transitioned from an 8 year old Montipora dominant system to a Euphyllia and Fimbriaphyllia dominant system.  The Atlantik Icon has more than enough PAR (Photosynthetic Available Radiation or Photosynthetic Active Radiation) for high flow and light demanding small polyp stony corals. This unit is mounted 18 inches above the water line and the panel provides full coverage down to the bottom of this 24 inch deep tank.

Transition from SPS to LPS

With the transition I had to dial down the intensity for the large polyp stony corals that are now in the re-aquascaped system.  I have been running a simulated AB+ spectrum (typically all blues from 400nm-490nm at 100% and red/whites only at 24%) with the SPS corals but now set them to 50% and 15% respectively for LPS in this tank setup.

The Torch corals (Euphyllia glabrescens) have definitely thrived under this light. I moved all these corals from a 40 gallon breeder lit by Kessil A80s.

The Verdict…So Far

In summary, this light is a great option for any system.  I love the full coverage compared to puck-style LED configurations. The App is fairly straightforward once you get used to it. Make sure to keep the Automatic Updates enabled for the vendor to release fixes and new features. The vendor has been very responsive in fixing bugs reported so provide feedback when possible. Typically once I dial it in I do not touch it. As with water parameters, you want to keep the lighting stable as well.

So far the hardware is solid, and earns its premium price tag. Ultimately the true test will be understanding the long term reliability of this fixture on a 12 hour photoperiod for the next few years and see how it compares to others.
