The details behind claims that a product or device can reduce your energy bills will always reveal the validity of the claim. Where electrical energy bills are concerned, you can certainly lower your energy consumption by switching to energy efficient LED lights, but you will be better able to reduce your energy bills in parallel to your lower energy consumption if you gain a better understanding of how LED lights work and how you can optimize your usage of those lights in your power consumption patterns
First and foremost, LED lights do generate the same or better quality lighting as traditional incandescent or fluorescent lights with a fraction of the energy input. Incandescent bulbs dissipate 80% or more of their electrical energy input as excess heat. LEDs convert substantially more of that energy input into light. As a result, you may be able to get the same amount of light output from an LED bulb that consumes 10 watts of electrical energy input as you would out of an incandescent bulb that consumes 100 watts.
Because of this higher efficiency, LED bulbs are more appropriately rated according to the amount of light, measured in lumens, than they are according to their input wattage. If you are replacing your incandescent lights with LED bulbs, make sure that you replace lumens for lumens and not watts for watts. If you use a 100 watt LED bulb in place of a 100 watt incandescent bulb, not only will you generate far more light than you probably need, but you will not reduce your power consumption or your energy bill.
Energy Efficient LED Lights
Understanding your energy bill is a second component of lowering the amount you pay. Many consumers look only at the bill amount without understanding how that amount is determined. Utility companies charge for electrical power on the basis of how many kilowatt hours (kWh) of electricity you use. The average national average rate is about $0.12 per kWh. If you believe that you are consuming fewer kWh of electricity after you have installed LED lighting but your electricity bills are not going down, compare your kWh usage before and after you installed those lights and confirm that your utility company has not increased its rates.
Lastly, if you elect to replace only a few of your lights with LED’s, go first for the lights that are used more frequently or that consume the most electricity. Outdoor lighting is one of the worst offenders for electrical power consumption. If your yard lights are on frequently or you use outdoor lighting to accent exterior features of your home, you will save proportionately more energy and reduce your utility bills further if you focus on those power-hogging lights.
If you have replaced all of your existing inefficient lights with LEDs and your utility bills are still not going down, take a closer look at your electricity bill to compare kWh consumption over different time periods and at different times of the year. If that power consumption is consistently high even after you have installed LEDs, your electrical system may have a flaw that requires professional analysis and correction.
Reducing your energy bills with efficient LED lights is only one reason to switch to this modern lighting technology. LEDs are more versatile and provide better design and control options than most other forms of artificial illumination.
