This is an LED light kit that can be put inside a used jam jar along with a small solar panel to provide a few hours of light in the evening - or during power cuts. 
 
The kit consists of a small solar panel, an electronic assembly, a board with LED lights, metal fixings 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.
 
There are 3 types of kits available.
 
JJSOLAR - Round - 2LED is a small round board (45 mm diameter) with 2 LEDs which is suspended below the lid. The solar panel is 63 x 30 mm.
JJSOLAR - Rectangle - 2LED is a small rectangular board (55 x 35 mm) with 2 LEDs which is attached to the lid. The solar panel is 63 x 30 mm.
JJSOLAR - Rectangle - 4LED is a larger rectangular board (75 x 35 mm) with 4 LEDS attached to the lid. This unit will come on Automatically when turned upside down. The solar panel is 60 x 60 mm.
 
Once assembled, just leave the jar on a window sill. The red LED will light up to show that the battery is charging. The brightness of the red LED is an indication of how intense the charge is - brighter LED means more charge.
 
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 many hours after a full charge. Just leave it out on a window sill to charge up the next day.
