LEDs are at the forefront of light industry discussion because they are such a gamechanger when it comes to energy efficiency and lifespan. But how do recent developments to LED technology affect the everyday consumer? What’s the simplest way to navigate this uncharted territory when shopping for LED light bulbs? The very recent availability of an LED replacement for the common household incandescent lamp has created a world of new potential, and along with it a whole new set of standards. In this post, we will be discussing the various ways to distinguish between the different LED options.

1. Light Output
Incandescent lamps have always been measured in watts, because for a really long time people equated the electricity it took to light a bulb with the luminosity it created. So “60 watts” came to mean “the brightness of a 60-watt incandescent lamp,” even though luminosity is measured in lumens, not watts.
With the introduction of more energy efficient lighting, however, this standard doesn’t work. It takes significantly less wattage to produce the same amount of light in an LED or fluorescent lamp, so it’s important for consumers to understand the luminosity of a bulb rather than simply its wattage.
Luminosity, or lamp brightness, is measured in lumens. The chart to the right demonstrates the amount of lumens a standard incandescent light bulb produces, so if you’re used to watts you can easily figure out what lumen count you want in your new LED bulb.
An LED lamp’s packaging or product description might mention how comparable its lumens are to the light output of a 60-, 75- or 100-watt incandescent bulb, but it’s wise to know ahead of time what luminosity you want just in case the incandescent watt-equivalent is not included.
Takeaway: Lumens are how the brightness of an LED light bulb is measured. You’ll choose your bulb based on how bright you want the light to shine, not by how much energy it will be using.
