LIGHTING & ELECTRICAL:
The lighting over the reef consists of:
- 3 x 1000w - 6,000 K
- 3 x 400w - 20,000 k
These pictures also show the supplementary glass "support structure" at the top of the aquarium.
Note that the ceiling and front hatch panel are lined with highly polished aluminum that serve as secondary reflectors.
This picture taken from the elevated walkway behind the aquarium. There are three lindividual ighting fixtures each of which contains one 1000 watt bulb and one 400 watt bulb.
This picture was taken from the opposite end of the aquarium. Note the four integrated fans (at the far end) that create significant air-flow over the surface of the aquarium.
Note the hinged hatch on the left which is covered with highly reflective aluminum.
A separate electrical sub-panel was installed to service the lights and pumps.
This sub-panel is situated in a remote service room located approximately 20' from the aquarium.
This room contains the electrical sub-panel, ballasts, timers, the chiller, RO system, 2 vats of replacement water, etc.
The electrical wiring (and some hoses and tubing) run through the ceiling from the remote service room to the aquarium.
All electrical circuits are protected by GFI breakers.
The lights run on 220v and the pumps (11 Iwakis) run on 120v.
I have used mechanical timers for the lights as I find them to be more reliable.
Please note that I have opened the sub-panel and taken the covers off of the ballast boxes for this picture.
I will be posting other "behind the scenes" pictures over the next several days.
