You can optionally switch off 2 of the LEDs so the lamp stays on
longer in winter or in continued poor weather. Using the detailed
instructions, the various parts such as resistors, LEDs,
switches, etc. are soldered to the PCB step by step. Once the
PCB is fully assembled and installed in a PET bottle, you will
have a cool, fully functional solar lamp.
With this cool soldering kit you can turn a standard PET bottle
(min. neck width 28 mm) into a great solar lamp. The solar cell
charges the rechargeable battery in this kit during the day. When
it starts to get dark, the lamp automatically switches on and stays
on all night - depending on the battery level. It uses a total of 4
white and one rainbow (multicolour) LEDs.
How the solar-powered PET bottle lamp works
This solar bottle lamp is one small step in this
The oceans are full of them and the piles of rubbish keep
growing. Not recycling PET bottles is a big problem for the
environment and for humans and animals too. It's time to break
new, innovative ground.

to build this solar lamp is your active and
