Good Morning,
We had a few leaks that slowed us down more then we anticipated but with all the leaks sealed the tank was fully filled and been running now 48 hours without any drips whooohooo.
We have mounted the lights, and a small wall that will hide them will be done next but wanted to show what the lights look like before the wall is placed up. Even without the wall up the light spillage into the room is small as the 30 degree reflectors installed seem to keep the light over the tank.
We went with the Amazonas 960 iCon (
https://orphek.com/amazonas-960-reef-aquarium-led-lighting/), each light weight s10.6 lbs. The cord for the light allows for it to be mounted high as it over 15 Feet long allowing us to channel them down along the chimney to the power supplies.
The light itself has 4 Channels, 2 Blue, 2 White (Channel 1 - 18000K XP UV 380nm – 700nm, Channel 2 Blue – 450 – 460nm, Channel 3 Blue Plus XP – Blue /Violet/UV – 400 – 500nm and Channel 4 8000K White )
The lights came with 60 Degree Lens and I had to replace them with 30 Degree Lens which was very easy to do. You loose the clips the front glass pops off and the reflectors just twist off:
These lights do not have fans as the LED assembly is attached directly to the heat sink.
We went with Three per Orphek recommendation, these are 7.2 Feet off the Bottom of the tank in the air. Here they are over the tank before the wall, and painting is completed
What about the PAR, We turned the lights up to 100% and brought out the Apogee 510 and said let see what the numbers look like and all we can say these will not be at 100% hehe.
At the top of the Tank the PAR Reading was:
1861
The PAR reading right below the water line was:
1025
The PAR level in the middle of the tank was:
743
Par Level at the Bottom of the Tank was:
508
We are placing egg crate at the bottom of the tank so we take take point readings equally before we remove the egg crates and place the live base rock into the tank.
Overall impressed with the lights and output. Having only 4 channels I thought would be a disadvantage but after playing with the lights for about an hour I was able to get the look we wanted.
