Light-emitting diodes (LED’s) are semiconductor devices that emit light when an electric current passes through them.
They are designed for better control over the electrical current making them have low current, heat and voltage. This results in longer lifespan, lower maintenance costs and energy savings. The warm yellow glow of street lamps are being replaced by the cold white light of LED’s throughout the world in an attempt to save energy. The lifespan of LED Streetlights is determined by its light output compared to its original design specification. Once its brightness decreases by 70%, an LED Streetlight is considered to be at the end of its life
