Achieve the Absolute Freshest-Looking Meats, Produce and Flowers with LEDs

From a nutritional perspective, meat that’s turned brown (oxidized) is the same as red meat. But, given the choice, we would all choose the red meat over the brown meat—it looks fresher!

When it comes to fresh foods and flowers, appearance is critical. We associate freshness with taste and nutrition and we’re generally willing to pay a premium for the freshest food.

A study by the National Grocer’s Association found perimeter fresh foods are the number one attraction at the grocery store for two-thirds of adult shoppers. After clean displays, the appealing appearance of fresh food is the top interest for shoppers.[1]

Perimeter fresh foods are expected to become more important for grocers as competition with online retailers on dry goods increases. Thus, how fresh food is presented to shoppers is vital.

A simple and effective solution for supermarkets is the lighting in their fresh food displays.

Think about it—ever seen yourself in the mirror under fluorescent office lighting? It’s not a good look, especially when compared with the golden light from the setting sun, or the soft light from the candles in a nice restaurant.

Lighting makes all the difference.

amerlux tradition

And the scientific research shows foods look freshest under LEDs: a study in the Journal of Animal Science objectively measured the redness of meat under low UV fluorescent lights compared with LEDs. The meat under LEDs oxidized far slower than the fluorescent and maintained a bright red color over several days.[2]

Quality LED lighting brings out the colors that are already in fresh foods, making them appear bolder and brighter, while also extending the shelf life of the products. What LED lighting doesn’t do is change anything about the product—e.g. using a red-tinted light on meat to make it look redder—which would be illegal.

The reason food looks fresher under LED lighting is the way we perceive light and color.

Light is made up of a spectrum of different wavelengths and we see the wavelengths

that are not absorbed by what the light shines on. Fluorescent lighting for example, emits high levels of green and yellow wavelengths and less red and blue wavelengths. This causes red meat to look more brown or gray, while white fat and bones take on a yellow or greenish tint.

LEDs are closer to natural sunlight—the “perfect” standard humans measure against—than legacy light sources like halogen and fluorescent. Under LEDs, whites are crisper, and colors are deeper.

As a bonus, LEDs emit almost no UV rays. UV rays prematurely age fresh items, so products last longer under LED light.

How You Can Protect Against Building Fires with LEDs

In 1992, a devastating fire ravaged Windsor Castle in the UK, burning through 115 rooms. It took 39 fire trucks and 225 firefighters more than 15 hours to quench the fire.

Dating back to the 11th century, Windsor Castle is one of the British monarch’s official residences and the largest inhabited castle in the world. The restoration efforts took five years and cost £36.5 million (nearly $82 million in 2018 dollars).

The cause of this catastrophic inferno? Hot lights.

A hot-burning halogen lamp touched a curtain in the chapel, sparking the blaze.

You don’t need to be British royalty to be the victim of lighting-related fires and disasters. The U.S. Fire Administration, a federal agency under FEMA, estimated that more than 100,000 nonresidential building fires caused $5 billion in property loss between 2014 and 2016.[i]

Electrical malfunction (a category which includes lighting) tied with cooking for fourth place for the most common causes of fires in nonresidential buildings.[ii]

The Windsor fire, along with the $5 billion recent US losses from fires, demonstrates the danger of hot bulbs touching combustible materials, but it’s far from the only way that lighting causes fires. Installing a bulb with a wattage that is too high for the fixture is a common cause of electrical fires and fluorescent light ballasts are a noted fire hazard.

On top of the substantial energy savings, maintenance savings, rebates and incentives, crime reducing effects, and employee productivity gains, LEDs are also a potent weapon against electrical fires.

Cool light

Known for their cool white light, LEDs actually come in every color temperature under the sun, from fireball orange to ice cold blue. But in terms of fire safety, LEDs give cool light—that is, they emit a tiny fraction of the heat that legacy light sources do.

Legacy lights are actually heating systems that happen to give off light as a byproduct of producing heat. According to the U.S. Department of Energy, incandescent bulbs emit 90 percent of their energy as heat and CFLs emit about 80 percent as heat. LEDs use about 20 percent of the total energy that legacy light sources use and waste almost none of it as heat.

Heat syncs

The little heat that LEDs do emit is safely dissipated through heat syncs—the odd-looking metal flanged component at the end of LEDs. The heat sync draws the heat away from the light source, extending the life of the LED and disperses it safely.

Legacy light sources lack such a safety feature and burn very hot. (There’s even a flashlight that can cook eggs with its beam!)

Low power consumption

LEDs draw very low amounts of power to illuminate a space. Besides the obvious cost savings here, it also makes LEDS significantly safer than legacy light sources. LEDs require less electricity, drawing less power through the building’s wiring, reducing the chances of an electrical fire from your wiring.

 

LEDs are the safe lighting choice for facility managers. Discover how you can reap these fire safety benefits, on top of the huge energy savings, reduced maintenance costs, and improve your employees’ productivity.

Colors that Jump Off the Wall: How LEDs Make Art Look its Best

Artists choose their colors with care, layering and mixing paints to achieve just the right look for their artworks. To experience the finished art as the artist intended it, the painting needs to be lit well.

In the past, the lighting options tended to be either too heavy on warm colors (incandescent and halogen) or overemphasize cool colors (fluorescent and HID). All light sources had color sacrifices built in and there was no way to get perfect color rendering.

On top of the color limitations, traditional light sources emit sizeable amounts of damaging UV rays. To preserve the artworks from effects of the UV rays, galleries would dim the lights. So, art patrons would see the art in darkened rooms. Incandescent and halogen lamps glow warmer as they are dimmed, exacerbating the color situation with an even stronger emphasis on warm colors in the art.

Now, those limitations are gone, and LED lighting can provide outstanding color rendering. Plus, LEDs emit a miniscule fraction of UV rays that legacy light sources do, so galleries can illuminate their spaces much brighter with LEDs, further improving the viewing experience.

“LEDs can provide a uniform output of light that covers different spectrums and by doing so, the color rendering abilities of the lights is increased significantly,” said Carlos Alonso-Niemeyer, principal at Reflex Lighting, Amerlux’s manufacturer’s rep for the northeast.

“LED technology renders colors with better vivacity. Imagine walking through a gallery and seeing paintings literally popping out because the color is more vibrant. This was very complicated and expensive to do in the past, but it’s very simple now with LEDs. A CRI of 90 really enhances the art and the colors jump out immediately,” continued Alonso-Niemeyer.

Until LEDs were developed, halogen lamps were the standard for color rendering. Except, they weren’t very good. They cast a warm hue over everything, especially whites and cooler-toned colors.

The Color Rendering Index (CRI) is one of the scales that measures how colors appear under a given light. Quality LEDs have CRI ratings of more than 90 for full saturation of color. With high CRI ratings like that, whites are white, reds are red, and blues are blue. Art seems to jump off the walls in LED-lit galleries.

Aside from the brilliant color rendering LEDs deliver, a further advantage is the lack of UV emissions. Over time, UV rays from lights gradually burn away at the materials—kind of like what would happen if you held a magnifying glass between the sun and a leaf. All lights emit some UV rays, but LEDs emit such a tiny amount that they are safe to use with fragile works of art without needing to dim the lights or positioning them far away from the art.

When the Queens Museum in New York City upgraded from halogen lamps to a state-of-the-art LED track lighting system, they found immediate improvement in how they could light their exhibits. Curator Larissa Harris said under the new LEDs, “The light levels were more appropriate so that the works could be seen more accurately. They were lit brighter than before [with the halogen lights] and looked better.”

Solving 5 Problems for Lighting Designers Through Innovation

Light is a very technically difficult medium to work with. It’s ephemeral and changes throughout the day and with each season. Also, you can’t generally see light until it splashes across a surface.

As with most areas of design, when it’s done well, good lighting design is often nearly invisible—but when it’s done badly, it’s glaringly obvious.

To deal with these challenges, lighting designers need lighting solutions that can deliver on both practical and aesthetic fronts.

Whether it’s a custom solution to highlight the unique features of a space or simply delivering consistent quality over and over, Amerlux is in its fourth decade of providing innovative solutions to lighting designers.

“Amerlux has listened to the requirements of lighting designers to provide products that make successful projects,” said Carlos Alonso-Niemeyer, principal at Reflex Lighting, Amerlux’s manufacturer’s rep for the northeast.

Lighting designers have broad requirements for lights and they prize lighting solutions that furnish excellent glare control, color consistency between products, and compatibility with control systems, while delivering beautiful light distributions.

Integration

Sometimes the light fixture is meant to be the centerpiece of a space, (e.g. a decorative chandelier), but more often than not, designers want fixtures that blend in and don’t draw attention to themselves. They need fixtures that will put the spotlight on other elements of the space, rather than take the spotlight themselves.

Glare control

Glare is the visual discomfort humans experience when a bright light source is within a direct line of sight. Designing to avoid glare is a big part of what lighting designers do.

“Glare produces a lot of discomfort to users, and it’s a big issue with LEDs. LEDs are point source lights and they can be very glary,” said Alonso-Niemeyer. “Lighting designers want to have a ‘quiet ceiling,’ meaning the ceiling doesn’t have areas that bother our eyes. The ceiling should be a uniform space without sparkles and glare.”

Tools Amerlux provides lighting designers in the fight against glare include performance lenses and patent pending light block shields that provide coverage when lenses shrink.

Consistency

Rarely does a project require only one kind of light. More often, designers use a combination of different lights—task lights, down lights and ambient lighting—for the optimally lit space. Lighting designers need lights that are consistent; products should be consistent with each other and within their own product family. A common problem with legacy light sources is they color shift over time—some in just a few hundred hours of use.

“When you put quality products together, they will have a consistent shade of color temperature,” said Alonso-Niemeyer. “Products without such quality would have pinkish or green hues and may have different color hues between them.”

Controllability

LED lighting is infinitely controllable. With the right system, you can do basic things like dim the lights, use timers and connect them to occupancy sensors as well as more advanced things like daylighting for maximum energy efficiency and color tuning for optimal cognitive functioning among workers.

“LEDs work with drivers that control them, and the drivers have different protocols that control them,” said Alonso-Niemeyer. “When you control LEDs and dim them, some products tend to flicker, or the dimming effect doesn’t work. Lighting designers want to make sure that the drivers and controls work together.”

Light distributions

The light distribution of a fixture is an important variable lighting designers look at and their needs vary depending on the type of light. “With linear products, lighting designers want a wide distribution (also called a ‘batwing’ or low-peak intensity distribution) for a uniform ceiling,” said Alonso-Niemeyer. “With downlights, they need a clean beam, one that doesn’t leave striations and halos on the walls.”

 

For more than 30 years, Amerlux leveraged customer feedback as a critical source of new product innovation, working closely with lighting designers and architects.

“Our inspiration truly comes from listening and we take a thoughtful approach to lighting,” said Bill Plageman, vice president of marketing at Amerlux. “Innovation is about taking disruptive technology that’s emerging and understanding exactly how it will be used, so we listen to our customers, as well as scientists, designers, doctors, retailers, and other experts in the industry and consider their input very carefully before we launch new products and solutions.”

How to Slash Energy Bills, Crime with LED Streetlights

top streetlights

Old, ineffective lighting is expensive. It guzzles down energy like a pig, racking up power bills in the thousands or millions of dollars, while casting inferior quality light on your streets and sidewalks.

There’s a solution to this problem—a solution that the cities of Los Angeles and Portland, Oregon have already taken advantage of to slice their power costs by 75 and 60 percent, respectively.

The solution is retrofitting street lights with energy-efficient LED lighting.

And thanks to legislation, like the American Recovery and Reinvestment Act of 2009, there is $17.5 billion available to companies, municipalities and federal agencies to finance LED upgrades. Plus, there is a wealth of additional rebates and incentives (which we detail here) that organizations and cities can harness for LED lighting projects.

For an effortless lighting upgrade, Amerlux has partnered with Facility Solutions Group (FSG) to launch a free energy audit program. This program helps municipalities, developments, universities and companies see what they could save and capitalize on all available rebates and federal monies.

“Amerlux listens intently to solve marketplace problems with innovation,” said Amerlux CEO and President Chuck Campagna. “City managers and facility managers realize that they can reduce energy consumption and crime by retrofitting with our Avista light engine. However, they don’t always know enough about their existing lighting fixtures to begin, so we have partnered with FSG to help our customers fast-track the process.”

In this collaboration, FSG is the audit and installation arm, while Amerlux supplies the Avista LEDs.

Designed for extremely easy retrofitting and delivering outstanding light quality for a fraction of the energy required by other light types, Avista LEDs are the optimal LED streetlights.

With its efficient design, the Avista LED can illuminate an area with comfortable light with far less wattage—virtually maintenance free for years. The result is a well-lit area with fewer accidents, less crime and where people feel safe and comfortable.

Avista LEDs offer outstanding light quality, which not only makes people feel safe, it illuminates the streets and sidewalks better, making them actually safer. A recent study by the University of Chicago’s Crime Lab and New York City found that LED lighting cut nighttime crimes by 39 percent.[i] The report included serious offenses like murder, robbery, aggravated assault, as well as various property crimes.

To start the process, interested towns, developments and other facilities can contact 855.662.7199 for a free audit by FSG to determine what kind of lights are already installed and the projected savings from retrofitting with Avista LEDs.

“We can give a complete turnkey solution to customers with post-top fixtures,” said Bernie Erickson, FSG’s northeast regional vice president. “Starting with an analysis of the existing lights and energy costs, what the savings from the retrofit would be, and then complete installation.”

A member of FSG’s “Green Squad” of auditors will analyze the situation, counting the number of fixtures and the types of lights the customer already has, and verify that the Avista LEDs would work in the existing luminaires.

FSG will provide the customer with a comprehensive report and executive summary detailing the overall economics of the project, including existing energy costs, likely energy savings, maintenance savings, cost of the retrofit, all grants and rebates the customer is eligible for and how long the project’s payback period will be.

Cities and organizations all across the United States have already harnessed LED street and pedestrian lighting to lower their electricity bills and make their spaces safer. See how you can too!

Lighting Controls: The Next Frontier in Facility Management

 

top streetlights

LEDs have more control options than any light source before them. With the right controls, you can adjust LED lighting any way you can imagine. You can dim LEDs, change their color temperature and control them wirelessly. You can even have them mimic the sun!

Until recently, controls tended to fall into three areas:

  • Dimming, manually or with photocell.
  • Motion and occupancy sensors
  • Timers, to dim or turn lights off

All of these control types can help minimize energy costs and maximize utility by automating processes for facility managers. In the future, controls may also be used for anything from measuring crowd size, facial recognition and advanced energy saving techniques.

Current Controls

Some LEDs can also glow warmer when they are dimmed, emulating the way incandescent bulbs operate. This Dim-To-Warm technology makes for very comfortable light.

To further save on energy costs, you can implement time-based scheduling to turn the lights on and off automatically. Since LEDs turn on instantly, they are perfectly suited to work with occupancy sensors.

Daylight harvesting is another option. Also called “daylighting,” daylight harvesting dims interior lighting in a space when the ambient natural light is sufficient or when the space is unoccupied.

Wiring for The Future with 7-Pin Sockets

A standard receptacle, the 7-pin NEMA socket is an option on most exterior lighting, (including Amerlux’s Avista and Coach Style Lantern) that permits a wide variety of controls to be used, including old 3-pin controls, wireless controls, and most importantly, the controls of tomorrow that are being developed today.

Since LEDs deliver a lifespan of 50,000 – 100,000 hours, using the 7-pin option future-proofs their controllability. This way, your LED lights can be maintained with whatever controls come next.

With 7-pin sockets, you can exercise wireless control over your exterior lighting, dim the lights, monitor for faults, have a photocell in every luminaire and even a GPS, so each pole is automatically mapped for you. These controls make managing large networks of exterior lighting a breeze. Because they are compatible with 3-pin controls, you have freedom to upgrade your controls when it is convenient.

The wireless capabilities of 7-pin controls also make compliance with lighting codes like ASHRAE.90.1-2010/2013 and the 2012/2015 International Energy Conservation Code (IECC), far easier. These codes require exterior lighting to turn on/off via photocells and automatically dim at least 30 percent afterhours. You can set the dimming with a scheduled time control or via occupancy sensors.

The controllability of LEDs is a huge benefit of the technology and can deliver even greater energy savings in addition to making spaces more customizable and human-centric. Pairing LED lighting with intelligent controls makes for a smarter and more sustainable solution.

How LED Lighting Increases Employee Productivity and ROI

LEDs are known for giving organizations big savings by reducing energy and maintenance costs, but there’s another way they save money: increasing productivity.

Upgrading to LED lighting can have a substantial impact on an organization’s bottom line. An increase of just 1 percent in productivity can slash the payback period or even completely pay for an LED retrofit project.

One company profiled in a 2018 National Bureau of Economic Research paper enjoyed a 0.7 percent increase in productivity after upgrading to LED lighting.[ii] This translated to an increase in profits that shortened the payback period from 3.5 years (based solely on energy savings) to just a couple months (energy savings + worker productivity increases).

Other studies have found similarly dramatic improvements in worker cognitive function and productivity from using LED lighting. One study from the International Journal of Industrial Ergonomics—comparing fluorescent and LED lighting—found an 8.3 percent performance improvement in visual and cognitive tasks.[iii] The same study found employees working LED lighting had faster reaction times, reduced fatigue and increased activity.

An Indoor and Built Environment study found dramatic productivity increases and a boost in employee morale from the marriage of LED lighting and natural sunlight in facilities that use daylighting techniques.[iv]

The “3/30/300” rule is helpful to put these studies in perspective:

Developed by commercial real estate firm, Jones Lang LaSalle, the 3/30/300 rule says that companies typically spend $3 per square foot on utilities, $30 for rent and $300 on employees.

If your building is 15,000 square feet, then you’re probably spending around $45,000 on utilities, $450,000 on rent and $4,500,000 on employees. (The total amount adds up to $4,995,000).

Reducing energy costs by 50 percent would save you $22,500 annually. Improve space utilization by 10 percent and you save $45,000. Increase employee productivity by 5 percent and you save $225,000.

A small change in the employee category can have a huge impact on your bottom line. This is why a small productivity increase can outweigh the substantial energy savings LEDs deliver and make LED lighting projects quickly pay for themselves.

When you combine the energy savings, maintenance savings, rebates and tax incentives, and employee productivity increases that LED lighting delivers, the payback period can be as short as just a few months. It’s clear LED lighting is the next step in smart facility management.

How will you increase productivity in your organization? See how Amerlux’s suite of interior and exterior LED solutions can deliver huge savings and enhance productivity.

How to get someone else to pay for your LED lighting upgrade

In the long run, LED lighting provides enormous benefits to a city or company’s bottom line, delivering huge energy savings, maintenance savings and other benefits—such as decreased crime on city streets and increased productivity in workplaces. In the short term, upgrading to LED lighting can be expensive.

However, there’s a secret weapon in your toolbox that makes LED lighting more than affordable: Other people’s money (OPM). The only thing better than getting a great product is getting someone else to pay for it.

There are numerous opportunities available at the federal, state, and local level for incentives, rebates and tax credits to help offset the cost of switching to LED lights. These rebates and tax credits can shrink the payback period considerably, so you can quickly realize a return on investment.

When Portland, Oregon wanted to upgrade the streetlighting in its historic neighborhoods with Amerlux’s Avista pedestrian light product, they were able to take advantage of rebates from the Energy Trust of Oregon and the Oregon Department of Energy. These rebates reduced the project’s payback period, complementing the 60 percent energy savings Amerlux’s Avista LED delivered.

Here’s where to get OPM to subsidize your LED lighting upgrade, retrofit or new construction project:

Local Utilities

A talk with your electric utility company should be your first step in any LED lighting project. Most utility companies offer rebates or some other kind of incentive to upgrade to efficient technology like LEDs. These rebates can influence your purchasing decisions, so it is important to know early in the process what kind of savings are available. Some utilities can even provide design and commissioning assistance to you.

As an added bonus, utilities’ incentive programs are somewhat insulated from politics and are less likely to change with an election, unlike say, tax credits.

Check with your local utility to see what they offer and gain insight about their rebate process.

Database of State Incentives for Renewables & Efficiency (DSIRE)

5 Reasons Why LEDs are More Eco-Friendly Than You Think

LEDs are far and away the most energy efficient lighting option on the market.

During the last 10 years, government regulations and manufacturing improvements have made them more available.

But energy efficiency is not the only environmental benefit of LED lighting. Here are five reasons why LED lighting is more environmentally friendly than you might think:

  1. LEDs work for decades

The average LED light can provide 50,000 hours of service or more and many of Amerlux’s LED products are built to last well past the average rated life.

Such a long lifespan means less supplies need to be dedicated towards maintenance. Besides the obvious monetary savings this represents, that means energy and resources don’t need to be expended on maintenance and replacements. If an LED lasts for 20 years—which many easily can—that’s two decades where no new lights need to be purchased. This diminished demand means natural resources can stay in the ground and not be used up.  

  1. No toxic chemicals

Fluorescent light bulbs contain mercury and other hazardous chemicals. Exposure to these chemicals is dangerous to humans and harmful to the environment, which makes disposal difficult and resource-intensive (Department of Energy).

LEDs are free of these dangerous elements. Constituting a chip inside an epoxy resin, LEDs are very durable. If you drop one, you don’t need to worry about being subjected to mercury.

  1. Less sky pollution

Exterior lights contribute to the light pollution endemic to metro areas. Non-LED light sources are omni-directional, meaning they spew light around in 360 degrees. LEDs are directional, so they shine light in one direction. This distinction is important because omni-directional lighting wastes light—throwing it where it is not needed. LEDs like Amerlux’s Avista street light retrofit product deliver light directionally to comply with dark sky codes where light cannot be thrown above 90 degrees. Avista puts lumens on the ground, where it is needed. Including a horizontal disc, Avista shines downward and avoids causing light pollution because the light is directed to the ground instead of thrown into the sky.

  1. Different light temperatures are available

LEDs are often stereotyped as delivering unnaturally blue light. Like most stereotypes, this is inaccurate, as LEDs can provide light in a variety of Kelvin temperatures, ranging from the extremely warm 1800K, to the coolest of cools beyond 6000K. LEDs can emulate natural sunlight or deliver light at any temperature needed.

  1. Energy efficient

A discussion of LEDs’ eco-friendliness would be incomplete without mentioning their energy efficiency.  LEDs can cut energy consumption by more than 80 percent on average compared to conventional lighting. When Los Angeles upgraded their historic streetlights with Avista, their energy consumption dropped by 75 percent, while Portland, Oregon realized savings of 60 percent with their own Avista upgrade project. The Queens Museum in New York City cut energy usage by 90 percent when they replaced their outdated halogen lamps with Amerlux’s SPEQ track lighting system.

LED’s efficiency comes from how it converts electricity into light. Conventional lighting wastes up to 90 percent of the energy in the form of heat with only 10 percent emitting light. LEDs, on the other hand, convert about 95 percent of the energy into light, emitting only 5 percent as heat (Department of Energy).
