LED lights are light sources, whose technology was originally constructed in USA. There aren’t spare parts or breakable glasses; it doesn’t contain mercury nor toxic gases. There is no possibility of over-heating (diodes weaken as the time goes by after 6000 hours use); another characteristic of this kind of light is that it consumes little electric energy (80% of energy saving), then long working life (up to 100000 hours, id est. if it works everyday for 12 hours it can last around 11 years, and lose only 30% of its primal light quality).
There are 3 combinations of color: RGB – red, green, blue, but it is also possible to get a rang up to 16,7 million colors using special adapters. We could say that an era of LED light is slowly coming.
