Really? This I had to see! So I asked Herman to bring me one, saying that I’d reimburse him for the cost.
On Friday, he did just that. And while I could quickly see ways to improve on it, I thought it was a pretty cool device. What they did was cut the long tube into several shorter lengths of about a foot long each. Then they took two LED bulbs and stuck one in each end of each of the shorter tubes, embedded in a piece of foam rubber that served at the same time to plug the ends of the tube.
To power the LED bulbs, they built a case out of wood scraps, big enough to hold three D-cell batteries. A scrap piece of metal formed one contact, and a nail formed the other. Wires tied around the contact ran to the leads of the LED bulbs, with a switch in between to be able to turn the lights on and off.
According to Herman, these little units (batteries not included :) sold for 750 francs (about $1.50) and were used by people living in the suburban squatter areas of Ouaga when there was not yet any electricity. I tried it out and the unit puts out just enough light to be able to see what you’re doing.
In any case, I thought it was a pretty creative way to recycle fluorescent light bulbs!
