Pegasus Lighting Roundup: Lighting In March

Here’s what’s been going on in the lighting world this month…

In Lighting News…

A Wal-Mart store in Mt. Pleasant, Wisconsin has equipped all its indoor and outdoor facilities with LED lights. The areas now illuminated by LEDs include the sales floor, pharmacy, restrooms, stock rooms, and the parking lot. Wal-Mart expects to save at least 30% of their energy costs, compared to their old fluorescent lighting systems. Click here to learn more.

On March 5th “The Bay Lights,” an LED light sculpture, illuminated San Francisco’s Bay Bridge for the first time with 25,000 LED lights. The project only costs $15.06 per night to operate, and was designed by artist Leo Villareal on a laptop. Check out this video from the grand lighting ceremony:

Product Spotlight: Lighted Bathroom Exhaust Fans

Your bathroom should not be annoying.
It should be a rejuvenating space within your house. It should be a sanctuary of sorts, really. The problem is, there are just so many ways the place can get annoying…

…Like when it gets excessively moist and you’re constantly fighting back the mold.

…Like when you’re in there in the middle of the night under the glare of bright lights.

…Like when your lights are cheap, ugly, or just don’t match your style.

…Like when your loud exhaust fan makes it impossible to relax.

If your bathroom annoys you in one or more of those ways here’s how exhaust fans can solve each of those terrible annoyances:

For The Moldy Bathroom

If your bathroom gets too moist when you shower and you’d rather not cultivate a garden of mold where you clean yourself every day, get an exhaust fan. To pick one that’s right for you, you just need to determine the recommended fan capacity for your bathroom. This is measured in CFM (Cubic Feet per Minute), which is the volume of air the fan can remove from a room within a certain period of time. You can find your bathroom’s recommended CFM by multiplying the room’s square footage by 1.1 if you have an 8-foot ceiling, or by 1.5 if you have a 9-foot ceiling. For example, a bathroom of 60 square feet with an 8-foot ceiling would need a fan with a CFM of about 66.

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…)

How To Make Your Office Lighting More Energy-Efficient

White Cove Lighting in a Conference Room
This article is part of a series here on the blog about how to save the most energy with lighting in your home or business.

Lighting accounts for at least 28% of the energy used in the average office building. That translates to a pretty hefty chunk of the monthly budget. But, by making big and small energy-efficient updates, you can spend less and enjoy a more comfortable office environment.

Big Changes…

If you still use incandescent or outdated fluorescent overhead lights, it’s time for an upgrade.

LEDs use about 80% less energy to generate the same amount of light as incandescent light bulbs. They also last about 25 times longer. So, if you use incandescent light bulbs in your recessed cans, you should replace them with LED lamps or retrofits. LEDs excel at downlighting, because they’re naturally a directional light source. Today’s models have light output and color quality very similar to incandescent lights, so you might not notice the change until you look at your energy bill.

If you have older fluorescent lighting in your office (like T12s), you’re also not saving as much energy as you could. T12 technology is over 70 years old, and incidentally was taken out of production last year. If you exchange your T12s for T8s, you’ll use 45% less energy. Not to mention, the color temperature and light quality of fluorescent lights have improved dramatically over the past few decades, so new lights could be a huge morale boost for all the office workers.


Smaller Changes…

Office lighting isn’t just about what’s on the ceiling. To make sure you’re saving the most energy possible, you also need to take a critical look at the smaller light fixtures in the office.

Product Spotlight: The FreeLite Photoluminescent Exit Sign

Photoluminescent Exit Sign
I’m very excited to share one of our most innovative products here at Pegasus Lighting – the FreeLite Photoluminescent Exit Sign.

This special exit sign uses absolutely no electricity and generates light that can be seen up to 100 feet away!

How is that possible? Well, the sign’s innovative photoluminescent technology absorbs the ambient light around it and stores it to use when the lights go dark. It does this completely on its own; it doesn’t require any extra maintenance or upkeep. No attention at all, really.

You may have experience with other self-illuminating signs, but unlike those our photoluminescent sign isn’t radioactive (it contains no tritium). You don’t have to test it periodically, and it’s completely recyclable, so you don’t have to worry about extra disposal costs. (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…)

“How Many Puck Lights Do I Need?”

xenon puck light
Puck lights, which get their name from their hockey puck-like shape, are one of the most versatile light fixtures around. They fit almost anywhere and can function as under cabinet task lighting, display lighting, and even safety lighting.

If you’re still in the dark about how many puck lights you need for your next lighting project, just follow these guidelines.

First, determine what you’re going to use your puck lighting to illuminate.

For even lighting under cabinets or along bookshelves…


We recommend using 1 puck light for every 6-10 inches of cabinet or shelf space. If you’re lighting 11-18 inches of space, use 2-3 puck lights. For 19-26 inches, you’ll need 3-4 puck lights. For 27-34 inches, 4-5 puck lights. For 35-42 inches, 5-7 puck lights. For 43-50 inches, 6-8 puck lights, and so on. Just measure your space and divide it up accordingly! (more…)
