This post describes a LED light kit that can be put inside a used jam jar along with a solar panel to provide a few hours of light in the evening - or as an 'electronic candle' during power cuts.
Here is the kit as supplied. It consists of a small solar panel, an electronic assembly, a bracket, 2 x nuts and bolts and some sticky pads.
You can use any old jar that has been used for jam, peanut butter or marmalade. The only tools required for this project is a drill and a small screwdriver. Drill a couple of holes in the lid - one for the bracket that holds the electronic assembly and the other for the wires from the solar panel.
Once assembled, just leave the jar on a window cill. The red LED will light up when to show that the battery is charging.
When it's dark or there is a power cut, just switch the LEDs on. Make sure to switch off when you have finished. The LEDs should last about 2 hours after a full charge.
Just leave it out on a window sill to charge up the next day.
