The Difference Between LEDs and CFLs: Rated Life

Clock
This post is the third in a series focused on identifying important differences between light emitting diodes (LEDs), the light source of the future, and compact fluorescent lamps (CFLs), the light source of the present. To check out the rest of the series, click here

When deciding which light source to choose, one of the most important factors you should consider is how long the light will last.

A longer-lasting light bulb means you won’t have to spend as much money on replacement light bulbs, and you won’t have to waste time and energy on maintenance and upkeep.

In general, LEDs last about 10 times as long as CFLs. An LED’s rated life can vary between 25,000 and 60,000 hours. The rated life of most CFLs varies between 6,000 and 15,000 hours. (more…)

The Difference Between LEDs and CFLs: Mercury

This post is the second in a series on important differences between LEDs and CFLs, two of the most popular energy-saving light sources on the market today. You can read the first post about efficiency here.

Mercury is a toxic substance that can attack the brains and nervous systems of humans. CFLs (and all fluorescent lights) contain small amounts of mercury, LEDs do not. In the long run, this makes the LED a much safer, low maintenance light source.

Why do CFLs contain mercury? 

The mercury, when excited by an electric current, helps the CFL generate light. This small amount of mercury, barely enough to cover the tip of a ballpoint pen, poses no threat to your health as long as it remains contained within the light bulb’s glass envelope. You only need to worry about it if the light bulb should break.

To safely deal with your CFLs, take them to an EPA approved recycling center. You can learn more about the importance of recycling CFLs in this blog post: Don’t Toss That CFL In The Trash.

What to do if your CFL breaks…

If you wind up with a broken CFL in your home, follow these steps for safe cleanup and disposal: (more…)

The Difference Between LEDs and CFLs: Efficiency

LED Better
This is the first post in a brand new series about the key differences between compact fluorescent lamps (CFLs), the light source of the present, and light emitting diodes (LEDs), the light source of the future. We’ll touch on things like structure, function, and quality, so you can keep up with all the innovations currently happening in the lighting world…

One of the most obvious differences between LED light bulbs and CFLs is energy-efficiency. Yes, we consider both sources to be energy-saving, and both fall well within new government efficiency standards, but it’s a simple fact that LEDs use less power to generate more light.

We measure the efficiency of a light source (sometimes called efficacy) in lumens per watt (lm/W). If you’re unfamiliar with this measurement, we’re just talking about the amount of light produced by one unit of electrical power – similar to miles per gallon for a car.

In general, a good LED on the market today can produce 60-100+ lm/W, which is about twice as many as a CFL, which only produces about 30-50 lm/W. (more…)

Product Spotlight: LED Thin Under Cabinet Task Lights

Today’s feature is one of our most popular under cabinet light fixtures, and just happens to be 10% off right now here at Pegasus!

LED Under Cabinet Light

The LED Thin Under Cabinet Task Lights come in 4 lengths and 2 finishes, so you’ll be able to find one to suit your exact needs. And when it comes to features, this fixture is the cream of the crop…

  • Dimmable, bright white LEDs make it functional and flattering (its CRI is an excellent 87). 
  • The largest, 32″ fixture only uses 17.7 watts, and every model has a 50,000-hour rated life. It’s ENERGY STAR certified, so you know it’s for real.
  • The fixtures are low-profile and linkable, which means they’ll fit almost anywhere you need them, without being too distracting.
  • The LED lights are much cooler than other light sources, so you can keep produce and other perishables on the kitchen counter without getting them ruined.
  • Installation is quite simple; you can either hard-wire or plug-in these fixtures. (more…)

LEDs Allow New Method of Data Transmission

Computer Keyboard  and Monitor
At the University of Strathclyde, researchers are developing tiny LEDs that can deliver Wi-Fi-like internet access. Called Li-Fi (short for Light Fidelity), this system has the potential to transmit data several times faster than what we’re used to.

Professor Martin Dawson and his team created tiny LEDs, each about the size of an end of human hair, which flicker on and off thousands of times every second. By altering the length of these flickers, the lights can send digital information to computers and other electronic devices. Picture it as a sort of digital Morse code.

The micron-sized LEDs are made so small to allow for more data transmission at a faster rate. The university’s LEDs can flicker at a rate 1,000 times faster than larger LEDs. Why? Well, if you have 1,000 micron-sized LEDs, they can fit into the same space as a single 1mm LED. Each tiny LED acts as an individual communication channel, which allows the transmission of about a million times more data.

Suddenly, a large LED display, with each tiny LED acting as a pixel, can also allow internet communications. (more…)
