Solar garden lights can be found in most DY shops, especially during Summer.

There are many models including cheap multi-packs.

It is important to check if the lamp can easily be dismounted.
The ideal model is a lamp with a switch to cut any hidden consumption while the battery is charging (not only to switch off the LED light ) .
