Solar LED lighting is the most sustainable and economical way to illuminate outdoor spaces, because the lamps that use this energy are equipped with a battery that charges thanks to the energy supplied by the sun and therefore diffuses the light.
These are products that, for the most part, are installed in gardens or external passage areas. Their main feature is that they can be installed anywhere, because they do not need to be powered by the mains and therefore can be placed anywhere.
In most cases we are talking about lamps equipped with motion sensors that are recharged during the day thanks to the sun's rays, this allows them to be activated when people pass, avoiding waste when there is no one inside their area of action.
Naturally, these are products made to be placed outside and therefore built with materials that can withstand the elements, avoiding deterioration.
Some products specifically are equipped with technology that allows operation up to 5/6 consecutive days (even when the sun tends to hide) thanks to batteries that are recharged, through the solar panel, and that accumulate the right amount of energy.

Considering the detection system to determine the ignition, the LEDs contained in this type of lamps can make light up to 50 thousand hours, this makes these lamps products of long life.
