When I built the fishroom back in early 2011, I set up my lightrack to move it out of the way when needed. This isn't often because I use Lumenbright pendants which are way up off the water, but when I need to take them down for cleaning, this is when it's worth the installation back then.

In the picture above, it is pushed all the way back by via rollers riding the track hangers affixed to the ceiling.

The lightrack rolls back completely off the reef. If I an unscrewing something and it falls, it hits the floor instead of the saltwater. I can change out the VHOs easily, or like today I took out each pendant to wipe them down. The glass is removed and cleaned on both sides, then reinstalled in the rack. The process of cleaning all three takes about an hour.

Once done, the rack is rolled back into place.

Today I received new TwinArc bulbs. I've been running them for the past year, and it's time to replace them. This time I'm upgrading the lighting a little. For the past 10 years, I've been running 250w - 400w - 250w over my reef tanks. Now I'm going to use all 400w bulbs.

TwinArc bulbs have two arcs inside the metal halide bulb. One fires 10,000K light, the other 20,000K light.

These golden ballasts came from Reefbrite, and will replace my 10 year old 250w IceCap E-ballasts.

Next week I'll replace all the bulbs on the rack as well as the wtwo ballasts.
