Abstract: This work has reviewed briefly the efficiency of LEDs which is dominating the global light systems. It is documented and experienced that the LED is the result of artificial lighting and not much efficient during the outdoor lighting. When we compare this technology, we can conclude that the High-Pressure Sodium Lamps are more powerful.
