LED Lighting

LED lighting is a technology based on gallium nitride (GaN) property to emit light when voltage is applied.

LED-based contemporary semiconductor lighting systems have significant advantage over traditional incandescent and CFL lamps in terms of power consumption, luminous efficiency and lifespan. Moreover, they do not contain mercury and lead, which makes them environmentally friendly.
