CFL daylight bulbs and outdoor sockets from the hardware store + one old extension cord + some plate mirrors from a dollar tree store for reflectors.
And there you go, you can build a lighting set up with more watts then you could ever need for less than 40 bucks.
I had a plan to build one i had seen on a planted aquaria site for my 125. I was going to use 4-5 100w CFL daylights and the mirrors but i have not started yet.
(5 sockets at $3 ea, 5 CFL bulbs at $3-4 ea, 5 6"x6" mirrors at $1 ea.= 500watts for 40 bucks) And takes very little skill to put togther. If you can change a wall outlet or splice a extension cord then you can do this.
i did build one for a my planted nano 2.5g. i used 2 10w CFL daylights which put out the same as a 40w regular bulb. And that turned out to be a algae growing monster with that much light. So I dropped down to one bulb and it worked fine for a year. And then i lost interest.
I still have it if you wanted some pics, but it was just a simple little 2 hr throw together project.
Let me know.
