OK - enough about all the little problems I'm having. Lets talk about a happier subject - Lighting!!!
I've had this plan going through my head for months, about exactly how I'd put the lighting together. I knew I wanted an open aluminum frame: lightweight, rustproof, easy to work with, fairly inexpensive. It had to be mobile so I can move the whole thing away from the tank to get better access. I wanted MH, supplemented by T5. So I cruised the forums to see what was out there. I finally decided on four 400W dimmable ballasts from CoralVue with 12K ReefLux SE bulbs. Deciding on a reflector was a little more difficult. I originally wanted to go with the large LumenArc IIIs, but then I started hearing about the new 20†Lumen Brights. I was a little worried about the fact the Lumen Brights throw a fairly concentrated narrow beam and my tank is 36†â€"œ front to back. In the end, Mike at ReefSpecialty.com convinced me to give the Lumen Brights a try. I only wanted the T5s to cover the beginning and end of the light period (not for spectrum augmentation) so I went with four 36â€Â, dual bulb, retro-fit kits from Hello-Lights.com.
At first I was just going to get some 1†aluminum tubing from Lowes for the light frame, and do a lot of cutting and riveting. Then I happened across an aluminum construction system. It consists of 1†tubing (with or w/o “flanges†â€"œ you’ll see in the pics) that can be fitted together with fiberglass reinforced composite connectors. I had experience with this kind of system while I lived in Europe, so I knew that they produced very strong structures. Seemed like the perfect thing for a light frame so I placed an order. Cost was comparable to what I would have paid at Lowes for regular tubing.
Here’s what I received:
Here, you can see what I meant by flanges:
The flanges are actually intended as a base for flat (ply or MDO) panels when the tubing is used to create cabinets, etc. The panels then become the top, sides, bottom, etc. of the cabinet. The pic shows a tube with flanges on both sides. Tubes are also available with no flanges or only a flange on one side. The composite material connectors are driven into the ends of the tubing. You have to use a hammer to do this as the fit is very tight. Once it’s seated it produces a very strong connection:
I cut the tube with a power miter saw and carbide tipped blade â€"œ cut like butter:
Because I was going to have a lot of right angles, I often had to miter the flange portion of the tubing at 45deg:
