Energy Savings With LEDs

Replacing LED lights with conventional/fluorescent lights is an established energy efficiency improvement method
Input brief details about your existing lights and the number of lights you want to replace
Based on your inputs, we will calculate how much you can save on your energy bills by opting for LEDs

While the use of rooftop solar power is a good idea, it becomes an even better idea if energy efficiency methods are first adopted for your building. One simple way to achieve energy efficiency is through the use of LED lights in the place of conventional incandescent/flourescent lights. You will be surprised at the amount of energy and cost savings you can make from LEDs over its lifetime.

Get surprised by using the simple estimator below to calculate the savings achieved by replacing your conventional lamps by LED lights.

Energy Savings With LEDs

Inputs

Existing lights’ Wattage	“; echo number_format($i);echo” W
LED Wattage	“; echo number_format($j);echo” W
No. of lights to be replaced	“; echo number_format($b);echo ” nos

Result:

Energy savings from using 1 LED over its entire lifetime is	“; echo number_format($r); echo” units
Energy saving from using $b LED(s) over its entire lifetime is	“; echo number_format($n); echo” units
Monetary savings from replacing $b lights with LEDs over its entire lifetime –	Rs.$lll

Assumptions

Lifetime of an LED bulb is approximated to be 25000 hours

Here the replacement cost of lights is not considered. The actual savings would be higher if it was considered.
