LED or light-emitting diode is a semi-conductor device that emits visible light by consuming electric current. LED consumes less power by producing minimal heat. Enter your current lighting usage and updated LED replacement information in the LED ROI Calculator and know how much amount and electric current you save annually. Online LED Energy Savings Calculator to calculate the LED light savings by providing your energy usage, energy cost and maintenance cost.
Find the LED bulb and light Savings if the existing and proposed energy usage are 700 & 500 kwh, utility rate is Rs.500, proposed total energy and maintenance cost is 1000 and 900 Rs, existing total energy and maintenance cost is Rs. 500 and 700.
= (700 - 500) x 500
= (1000 + 900) - (500 + 700)
