Don't throw away those brackets!!!!
I had to replace the broken ballast in my light hood and went with the CFL option here. Great work OP. Used 3 2-socket setups for a total of 6 bulbs. 55 gallon tank.
I did exactly what the OP did, except I utilized the metal brackets that came with the 2-bulb sockets. You can use these to make a more solid mount to the hood than zip ties.
Here are my steps and pictures of the finished work:
1.[FONT="] [/FONT]I tore out the broken fluorescent ballast that was in the long light hood.
2.[FONT="] [/FONT]The inside was originally black, but I taped off the sides and painted the inside white with Rustoleum High Temperature spray paint. It gives it better reflective properties.
3.[FONT="] [/FONT]Home Depot didn’t have the 2-bulb sockets by themselves, so I bought 3 cheap hanging light fixtures ($5 each) that had the sockets in them.
4.[FONT="] [/FONT]While I had to disassemble the light fixture and remove half of a bracket, I was able to use the other half of the bracket to mount the sockets to the hood. (The metal piece shown in pictures.)
4a. Unscrew the bolts holding the two brackets and socket together.
4b. Save the 2 bolts, 2 nuts, socket assembly, & bracket with threaded screw portion on the end.
4c. Remount bracket with threaded screw on OPPOSITE side from where it was mounted before. (Wires should be coming towards the bracket from socket.) Use bolts & nuts to tighten into place.
4d. This keeps the wires neatly against the wall of the hood once you mount it.
5.[FONT="] [/FONT]Drilled holes for the threaded portion of the bracket to fit through the hood. (I either need to get a Dremel or bigger drill bits. It is a paint to use a small drill bit and use a circular motion to make a hole bigger.)
6.[FONT="] [/FONT]Attached with a rubber washer and odd decorative cap-nut provided in the light fixture.
7.[FONT="] [/FONT]Drilled a hole in the hood to mount the toggle switch.
8.[FONT="] [/FONT]Wired everything in parallel format.
9.[FONT="] [/FONT]Used mount-zip-ties to keep wires away from touching lights.
