LED is the most advanced lighting technology in the world. As CFL saves upto 80% Power compared to Incandescent bulbs, LED saves upto 50% power compared to CFL bulbs & helps you minimize your electricity bills every month. for example 5 Watt LED bulb can replace 18 Watt CFL Bulbs. It can be fit in normal B22 bulb holders & supports 120-220 Volts normal Indian input power supply.

You can Save electricity & save money by just replacing your old incandescent or CFL bulbs.

How? Calculate yourself.

Before that know the basic unit of electricity.  electricity is calculated in kWh & 1 unit is the 1 Kilowatt hour (kWh). In simple terms, 1 kWh is the amount of energy consumed by an electrical device (e.g. an electric heater) that uses 1kW (1000 watts) for 1 hour. An another example is 10 (100-watt) light bulbs used for 1 hour equals to 1KWh= 1 Unit

For Example, Incandescent light consumption in an average 1 bed room apartment:

Bedroom

Daily Hours of Use per 100 watt Lamp: 8 hr
Daily Energy Consumption: 800 Watt-hr

Bathroom (for bath & washing cloths)

Daily Hours of Use per 100 watt Lamp: 2 hr
Daily Energy Consumption: 200 Watt-hr

Kitchen 2 times (morning & evening)

Daily Hours of Use per 100 watt Lamp: 4 hr
Daily Energy Consumption: 400 Watt-hr

Living Room at evening

Daily Hours of Use per 150 watt Lamp: 6 hr
Daily Energy Consumption: 900 Watt-hr

Exterior at night

Daily Hours of Use per 100 watt Lamp: 10 hr
Daily Energy Consumption: 1000 Watt-hr

Now follow the comparison of different bulbs watts. As CFL saves upto 80% Power compared to Incandescent bulbs where LED saves upto 50% power compared to CFL bulbs.

The actual technical term for brightness is Lumens. More the lumens, brighter the light is. The number of watts & lumens is different for different bulbs. so choose your bulbs as per how lumen or brightness you required in your room.

As per the above example of 1BHK apartment, the total energy consumption for Incandescent bulb is 800 watt + 200 watt + 400 watt + 900 watt + 1000 watt = 3300 watt say 3.3 units per day. So, you consume 1205 units per year.

As compare to 100 watts incandescent bulb CFL takes an average 20 watts.

So the total energy consumption for CFL bulb is 800/100×20 = 160 watt + 200/100×20 = 40 watt + 400/100×20 = 80 watt + 900/100×20 = 180 watt + 1000/ 100×20 = 200 watt, so in total 160+40+80+180+200=660 watt say 0.66 units per day. So, you consume 240 units per year.

As compare to 20 watts CFL bulb LED takes 50%  or an average 10 watts.

If you use LED bulbs the electricity consumption will be reduced to 50% that means 120 units per year. You save 120 units. If the average rate of electricity is Rs. 8-10 per unit, you will save Rs. 900-1000 per year in electricity uses bill just replacing LED lights only.

Further the life of LED bulb is more than 10 times the life of incandescent bulbs. An every LED bulb has 8-10 Years life, Average usage six hours per day.

You saves in the cost of bulbs as well as inconvenience caused in buying and replacing the bulbs.

So, Don’t waste electricity & helps India to save Energy. Order LED LIGHT Bulbs at cheapest rates right now.
