This cool soldering kit makes it possible to build a great solar light from a standard PET bottle (bottle neck width min. 28 mm). The battery included in the kit is charged by the solar cell during the day. When it starts to get dark, the lamp switches on automatically and lights up all night, depending on the charge level of the battery. A total of 4 white and one rainbow (multi-colored) LEDs are used as light sources.
Optionally, the 4 white LEDs 2 can be switched off in order to extend the light duration in winter or in persistent bad weather. The luminous color can be switched between white or cool changing rainbow colors. The detailed, illustrated and handy 24-page instruction booklet enables and illustrates the structure even for beginners!
Once the circuit board is fully assembled and mounted in a PET bottle, a cool, fully functional solar lamp has been created.FOR THE SAKE OF THE ENVIRONMENT:
PET bottles: The world's oceans are full of them and the mountains of rubbish are growing steadily. Non-recycled PET bottles pose a huge problem for the environment and thus for humans and animals. By recycling one of the many used PET bottles by building this solar lamp, you are part of active and creative environmental protection! It is time to go new and innovative ways. A small step in this direction is this great soldering kit for a solar PET bottle lamp.BUILDING INSTRUCTIONS
