So I just started a new 10 gallon planted tank, and I decided I wanted to make my own lighting so here's what I did. . .
List of materials:
1 long window planter box
2 plug to socket light adapters
2 15 watt CFL bulbs
1 extension cord with 3 sockets at the end
1 can of spray paint
some aluminum foil
I took the planter and drilled a hole big enough for the extension cord to go through. I then plugged the adapters into the extension cord and screwed in the lights. I ran the cord through the hole in the back. I then screwed a piece of wood inside the planter box for the lights to rest on and I siliconed and duct taped the lights to the wood. Then I taped some aluminum foil inside as a reflector and painted the outside black. I get great light over my 10 gallon with this, and the whole fixture is about 24 inches long and only costs 15 dollars.
Thanks for looking!
