If you want to build a recycling gardenlight, you only need the following items:
1 canister 2.5 l for glass cleaner or car cooler liquids
1 lamp socket E 14 with energy-saving lamp
1 2-wire cable
1 junction box
1 Timberboard 20 cm x 3 cm about 200 cm long
1 round wooden stick 15 mm Dia. 300 mm length
Cut the Wood according to the dimensions of your canister.
Make the top part a little bit wider, so that you are able to adjust the ability of the unit to clamp the canister.
