Q: I’ve heard that LEDs and CFLs use about the same amount of power. Why should I pay more for LEDs? (September, 2014)

In residential screw-in applications, LED (Light Emitting Diode) and CFL (Compact Fluorescent Lamp) do have about the same efficacy as measured in: lumens of light produced divided by watts of electricity consumed.  Some advantages of the LED that might justify the extra cost are longer life,  better color and no mercury.

One other difference is how the light is delivered. LED lamps are typically made up of several individual LEDs. Each individual LED is directional, like a flashlight. This works great if you want to shine light in only one direction like flood lights or spot lights.  For omni-directional lamps, manufacturers must aim several individual LEDs in different directions. Each manufacturer has a little different strategy for accomplishing this.  It is important to evaluate each lamp for each application you have. If possible, turn on a sample of the light to see how the light is delivered and make sure it will work for you.

In our EnergyStore we have 6 different LED lamps that you can turn on and  compare side by side with several varieties of CFLs.
