So tonight I finished up my 40$ lighting system. I wanted something I could clip some aluminum shop lights to that was adjustable up and down so i can find what works best for this tank...
Ive got 3 of these lamps with three 15w daylight bulbs, and ive also got three 26w daylight bulbs. To start, im going with two of the lamps with 15w bulbs at about 8 inches off the top of the tank (so about 17" from the surface of the substrate.)
The hangers are electrical conduit piping with 90 degree elbows at the top...I put caps on the end of the cut pipe to prevent any abrasion with the 'picture hanging wire' going over them at 90 degree angles.. I ran the line through the horizontal adjustable pipe, down both vertical pieces and ran them through the opening of a weight underneath my dresser as the ballast.
Attached a washer and 3 cable ferrules one after another just as backup. The lights go up as I pull the weight away from the wall and go lower as I push it farther back. So far everything seems pretty sturdy! We'll see how the plants grow this week with these bulbs at this height.
The three aluminum light fixtures, three 15w bulbs and three 26w bulbs cost me about 20 dollars...
The electrical conduit pipes, elbows, connector brackets, endcaps and wire cost me almost another 20.
Im trying to find a way to securely attach the power cable for the lights to the horizontal bar so I can completely remove the clamp bracket for a cleaner look. Any ideas?
