55 Watt AHS Light Fixture
I just finished making a stand for a 45 gallon rimless tank, so now I need a matching light fixture to hang over it. I had a leftover AHS reflector and endcap, so it made economic sense to try to use it for this tank. I bought a Fulham Workhorse 3 ballast to use, at a good price, so now I'm starting the wood enclosure for it.
My hope is to make an enclosure which matches the design of the stand, but my first try was a flop. I tried to make quarter round, rabbitted molding so I would have round corners on the "box" fixture, but my router is too worn to let me do that well. I managed not to toss the bit at myself, but just barely.
So, I will try a different design. This one will be a solid birch top, which will get rounded corners after the assembly is complete. I will use a different rabbit bit, with a trim router, which is also old, but not so worn out, to cut the recesses along the sides for 5.2 mm maple plywood sides and ends. This way it won't be as heavy as a box made all of 3/4" wood would be.
I salvaged the 1 x 6 birch board I messed up, and now have it cut and edge glued for an approximately 8" by 30" box top. I use a bar clamp which is also a tool guide to guide my Skilsaw for accurate rip cutting. The Skilsaw is getting pretty worn too, but still works well enough for this project.
The reason for the size of the "box" is to allow for rigging up reflectors to help the 22 inch bulb cover a 36" tank with enough light, but without lots of spillover light.
