We wanted a solar powered light over our new entrance arbor. The problem is that most of the lights available are just plain ugly. And the solar panels on the cheaper models are usually mounted on the light itself making it impossible to place them in a shady spot.
I came up with a simple solution. First, I bought an inexpensive solar light intended to be mounted on a fence. I took it apart and desoldered the LEDs off the circuit board. Next, I soldered four wires to the former connections to the two LEDs. Basically, I created a extension cord to the LEDs. I mounted the LEDs on a small scrap circuit board and soldered the ends of the wires to them.
What I ended up with is a battery and solar power unit connected by wire to two LEDs that I could place in a more attractive enclosure. We had a candle lamp that Mrs. Homegrown found on the street that worked perfectly, but we could have used just about any fixture. We could now place the solar panel in a sunny location on top of the entrance arbor and then hang the light underneath.
Next on my agenda is to create lights from scratch that flicker like candles.
Here’s a primer on working with LEDs. Note that LEDs have positive and negative legs, so if you hack a solar light, remember to connect up the LEDs respecting the polarity.
