Lumens vs Watts Graphic

A common misconception that consumers make is just because the LED bulb uses a significantly amount less energy, the LED bulb will not be as bright. That is false. 

In the past, wattage has been used to measure brightness, but this is no longer accurate.  When determining the right brightness, you need to become familiar with lumens.  Wattage is strictly related to the amount of power or energy used. What are lumens then?

Comparing Heat emitted by different types of light bulbs

In fact, LED technology has improved so much that not only do LEDs require less energy, but they are producing a brighter, more consistent, and endurable life. To learn how to compare and analyze Lumens vs. Watts, give this blog a quick read.

Main Takeaways

  • Lumens: The measurement of the amount of light produced by the bulb.
  • Watts: Refers to how much power or energy the light draws from a socket.
  • Efficiency: The percentage of energy a bulb uses while considering the amount of energy that is wasted through heat and resistance.
  • LEDs: Use 80 percent of the energy they consume to create light.  20 percent is wasted heat.
  • Incandescent: Use only 10 percent of the energy they consume to create light.  90 percent is wasted heat.

Can LED PAR Bulbs be Directly Replaced?

Most PAR Bulbs use an E26 Medium Base.  The “E” stands for Edison or Edison screw which is a standard socket for light bulbs in North America.  The “26” means that it is a medium base.   Because of this, most LED PAR bulbs can easily replace halogen and incandescent bulbs utilizing the existing fixture.

The Complete “Edison” Series of Bulb Bases:

Replacing your old light bulbs with LED PAR Bulbs are the most cost-effective replacement option since they do not require any retrofitting kits or large upfront costs.

By replacing your old halogen lights and incandescent bulbs, you can easily reduce your annual energy costs by as much as $70.00/ per bulb, depending on the size and usage.
