LED lighting

LED powered light made from a baverage can

Solar powered lighting is one of the main applications for micro photovoltaic systems. The rapid advances in
light-emitting diode (LED) technology allows light generation at very high efficiencies.

When selecting a LED, the following parameters are of importance: how much light is emitted per Watt (lumen/Watt), how much it costs (lumen/Euro), how good is the light quality (color rendering index; 90-100 is very good, <80 not so good), and what is the light temperature.
