Light pollution is the brightness or light pollution that is generated at night by artificial lighting, primarily produced by outdoor lighting systems. This glow tends to raise the brightness of the natural background of the sky, reducing the capacity for observation of astronomical objects.

Solar energy is a renewable energy source, non-polluting and inexhaustible, that for use in outdoor lighting, from urban or rural, industrial and infrastructure areas, parks, campgrounds, sports facilities and unique venues, are installed more widespread solar lamps.

Besides the MICROLED PLUS has a much higher lifetime (50,000 hours). Whereby the amount of waste generated is also less.

Another area to consider in the use of lighting equipment, is the environmental pollution they generate, at the end of its useful life.

The Directive 2002/95/EC Restriction of Hazardous Substances in electrical and electronic equipment (RoHS "Restriction of Hazardous Substances"), prohibits the use of six hazardous materials (which are: Lead, Mercury, Cadmium, Chromium VI , PBB and PBDE) in the manufacture of electrical and electronic equipment.
