Clock The Difference Between LEDs and CFLs: Rated Life
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. Continue reading »

Mercury 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: Continue reading »

LED Step Lights At Home 233x300 How Durable Are LED Step Lights?
We recently received this question on our website about the durability of our LED step lights:

Can the lights set flat on the landing and be able to withstand the removal of snow, or are they too fragile for that?

If you’ve considered installing step lights on an outdoor staircase or an indoor staircase that gets a lot of wear and tear, this question has probably crossed your mind. After doing some research and hearing from a few customers about their own experiences, here’s what I’ve found:

The Hearty Light Source

For a quality outdoor step light, you couldn’t do better than an LED. LEDs don’t have delicate filaments or electrodes like other light sources. This lets them withstand jarring vibrations like heavy foot traffic or shoveling.

Also, LEDs love the cold – they actually last longer in lower temperatures. So, they’re perfect for outdoor lighting in chilly climates. Fluorescent lights, on the other hand, don’t thrive in the cold. They have difficulty starting in temperatures lower than 32 degrees Fahrenheit.

How Fragile Are The Housings? 

While LEDs by themselves are downright robust, they aren’t the sole component of a step light. The glass, metal, or plastic housings and covers might not hold up to vigorous scraping or pounding if installed flat on a stair. Plus, if they’re not completely flush, they could be a tripping hazard.

Jim from PA. a proud owner of LED step lights, offered us his solution to this problem:  Continue reading »

LED Better 300x199 The Difference Between LEDs and CFLs: Efficiency
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. Continue reading »

Kozzi Computer Keyboard  and Monitor 426x304 300x214 LEDs Allow New Method of Data Transmission
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. Continue reading »

PAR LED LED Rebates For 2013
Considering switching your commercial lighting to LEDs this year? Learn how to get the most out of lighting rebates and incentives. 

Have you gone shopping for new light bulbs or fixtures lately? If the answer is yes, you’re probably aware that LED lighting options have saturated the market as energy efficient alternatives to incandescent, halogen, and fluorescent lights.

But, what you might not know is that there are tons of rebates and incentives out there for buying LEDs that can help you save money when making the switch.

Since January 2012 the number of rebate programs for LEDs has increased by 54%.

Here’s an overview of the kind of rebates your company can expect in 2013:

Rebate Snapshot LED 1 13 LED Rebates For 2013

If you’re already familiar with rebates from electric utilities and government organizations in your area, you may notice that the dollar amounts for most rebates have decreased over the past year. The average rebate for an LED replacement lamp has gone down by 7% since last January. Rebates amounts also decreased for LED fixtures: recessed down lights decreased by 66%, accent lighting by 12%, and high bay fixtures by 8%.

You needn’t be alarmed by these numbers, though. They’ve only been adjusted to match the lower prices of LEDs in 2013. Less money is necessary to make purchasing an LED financially attractive. Also, since there are over twice the programs this year, money is even more accessible. Continue reading »

Light Bulb Question Mark Orange 300x300 Myth: LEDs Are Too Expensive
This is the fourth post in a series on explaining common misunderstandings about LEDs. The previous installments include, Myth: LEDs Don’t Save Power, Myth: LEDs Don’t Work, and Myth: LEDs Are Light Bulbs

$50 for a light bulb? Eesh. Who would want to pay that when you could buy an incandescent light bulb for $2.50, and use the extra cash on a new outfit or a tank of gas? Why pay more when you can pay less?

Is The Price Right?

It’s no secret that LED light bulbs cost more than other light sources – incandescent, halogen, and even fluorescent – but those price tags don’t tell you the whole truth. They leave out the fact that you’re saving money by spending a little more for a quality light bulb.

Let me break it down for you:

LEDs last much longer than older kinds of light bulbs. If you pay $29.90 for this LED A lamp, and it lasts 23 years (give or take), that price evens out to cost you just over one dollar per year!

If you buy a cheaper light bulb, like a halogen A19 for $3.25, and it burns out after a year or so, over those same 23 years you’ll have spent about $75 on  replacements. Ouch! Continue reading »

Light Bulb Question Mark Pink 300x300 Myth: LEDs Are Light Bulbs
This post is the third installment in a series on disproving common misconceptions about LED lights. The first myth we addressed was whether or not LEDs save energy – read that here. Then, we covered whether or not LEDs actually work – read that here

Okay, okay. Yes, LED light bulbs do exist. LED light bulbs are everywhere these days, actually. No prevaricating on this blog! But, I’m not lying when I tell you LED light bulbs aren’t light bulbs. They emit light, and yes, they come in indisputably bulbous shapes, but they’re so much more than simple light bulbs.

What Your Light Bulb And Your Laptop Have In Common

It may be more accurate to describe the LED light bulb as a type of computer.

Where old fashioned incandescent light bulbs create light with rudimentary filaments, LEDs create light with the same kind of technology that makes your computer do its thing: the microchip.

Like computers, many LEDs can be easily programmed, and can even connect to WiFi. With this kind of simple-to-manipulate technology, LEDs might just surprise you with their many capabilities.

What LEDs Can Do

Here are just a few of the possibilities… Continue reading »
