Eureka! Everything You Need to Know About Light bulbs

The light bulb was only one of Thomas Edison's 1,093 patents, but some would argue that it is the most important. Anyone who has ever experienced a power outage would be inclined to agree! The immediate plunge into darkness makes you realize how helpless you are without light, and how much time and planning is saved by having it on demand. Let's learn more about these bright bulbs, and how they have evolved over time to become more efficient.

The three metrics you should know that relate to light bulbs are lumens, wattage, and light color. Lumens are the measure of brightness, wattage is the amount of power it takes to light the bulb, and light color (measured on the Kelvin scale) determines whether the light takes on a yellowish or whitish hue.

There has been a sea change in the past few years, with the slow phasing out of standard incandescent light bulbs in favor of more efficient models such as LED and CFL. The latter two types can help to cut down on energy costs, and also have a longer lifespan than previous bulbs. Read our infographic for more information on the difference between each bulb type, and also tips on how to recycle your outdated bulbs!
