Conventional bulbs waste 90 percent of their energy in generating heat when lit. Replacing them with energy-efficient lamps can lower the electrical bill for lighting up to 85%. See how much you can save if you switch to energy saving lamps.

CALCULATE YOUR SAVINGS

Conventional Light Bulb

Wattage of Selected
Conventional Lamps (W):
Number of Lamps: Burning Hours per Day (hr): Unit Electricity Cost in your Region
($/kWh):
 
Total Electricity Saved (kW/Year): 0.00
Total Electricity Cost Saved ($/Year): 0.00
Total Reduction in CO2 (Kg/Year): 0.00

 

Calculation Formulas:

Total Electricity Saved (kW/Year):
(Number of Lamps x (W of selected lamp - W of Recommended lamps) x Burning Hours per Day x Default no. of days per year) ÷ 1000

Total Electricity Cost Saved ($/Year):
Total Electricity Saved (kW/Year) * Unit Electricity Cost in your Region ($/Kwh)

Reduction in CO2 Emission (Kg/Year):
Total Electricity Saved (kW/Year) * Emission of CO2 in consuming 1kWh (Kg)

Assumptions:
Emission of CO2 in consuming 1kWh (Kg): 0.616
Default no. of days per year: 365
