LED Lighting Definition

Take advantage of our LED (Light Emitting Diode) Lighting calculator and determine just how much you can save annually on your power bill, when you upgrade your home or office’s lights to LEDs bulbs. LED light bulbs consume less energy than incandescent and compact florescent light (CFL) bulbs, and last much longer and they make much more efficient use of the power supplied to them.

LED light bulbs require just a fraction of the wattage required to power a traditional incandescent bulb. For example, 60 watt incandescent bulb will net you the same amount of lumens, units of light, as a 7 watt LED bulb — and the LED bulb would last roughly 40 times longer than the incandescent.

The epoxy build of LED light bulb makes them much more durable than glass and copper builds of traditional light bulbs, potentially saving you money on replacing broken bulbs. The light emitting diode features a positive and negative lead, which only allows power to pass through in one direction. The unidirectional power flow helps to eliminate shorts, and ensures that LED bulbs have long lives.

The diode itself is also extremely proficient in utilizing the every bit of power that’s feed into it, while traditional bulb may lose up to 80 percent of input power due to heat dissipation. Try our FREE calculator, and then customize the widget for your website!

Our LED Lighting Calculator factors the following variables to determine your energy savings:

  • Number of Bulbs
  • LED Wattage
  • Current Bulb Wattage
  • Hours of Use

After you’ve completed the fields in the LED Lighting Calculator, simply click on the “Calculate” button to view your annual electricity savings. You’ll also to calculate the amount of carbon emissions you’ll be cutting by making upgrading your home or office’s lights to LED bulbs.

Tips and Considerations

The annual saving are based at rate of 20 cents per kilowatt hour.

The “Hours of Use” section of the LED Lighting Calculator concerns your daily averages for light bulb uses. To determine how many hours you should enter into the field, take an estimate for each bulb’s daily usage. Add each bulb’s estimated hourly usage, and then divide the hourly total by the total number of bulbs to find out your home or office’s daily light bulb usage.

It’s likely that all of your home or office’s bulb aren’t of the same wattage. Like your “Hours of Use” estimate, you’ll also need to determine an average bulb wattage to complete the LED Lighting Calculator’s “Current Bulb Wattage” field. Add the total amount of watts of your current light bulbs, and then average that number by the total number of bulb.

Get even more precise and average the total wattage of your prospective LED bulb, using the same formula you used for the “Hours of Use” and “Current Bulb Wattage” fields.
