This fixture has worked extremely well for 4 months now. I enjoy it so much I wouldn't change a thing, other than the little mistakes I made in making it.

Now, I am fed up with high light intensity. Bah! I took a week vacation, followed by another week recovering from a head cold, followed by almost another week being too busy with one of my wife's projects to work on the tank, and....... Well, I have a mess. Good time to make major changes.

With this fixture I could replace the 55 watt bulbs with lower wattage, but then I would lose the 9325K bulbs, which I really love. So, I will raise the fixture by about 9 inches, which will be the equivalent of reducing the light intensity by about 38%, from about 2.4 watts per gallon to the equivalent of about 1.5 watts per gallon (based on the intensity at the substrate level). This will entail only removing the bracket from the wall and relocating it 9 inches above the top of the tank. Easy to do. One more thing I like about the design.

I will probably be posting a new thread about the new setup, once I figure it all out.
