The Advantages of LED Hospital Lighting

For as long as we can remember, hospitals and healthcare facilities have been using incandescent and fluorescent light fixtures to illuminate patient rooms, offices, hallways, bathrooms, etc. These lights have been the go-to because of their output, cost, and availability. What hospital facility managers fail to realize is that incandescent and fluorescent lights aren’t dependable and can have many negative effects on patients. When it comes to hospital lighting, LED lightss and fixtures are the best alternatives for many reasons.

Organizations in the Health Care field are constantly looking for ways to improve their patient experience, while simultaneously trying to keep operating costs as low as possible. Lighting upgrades provide the ideal opportunity to improve a facility’s performance and significantly reduce energy and maintenance costs.

Reduce costs

  • Reduce energy consumption by up to 50% with LED lighting and up to 80% through lighting controls 
  • Comply with energy legislation and support sustainability targets
  • Reinvest cost savings to enhance the healthcare environment

Enhance comfort

  • Use ambient lighting to relax and reassure patients
  • Attract and retain valuable staff through a pleasant working environment
  • Create a relaxing and welcoming environment in reception, examination, and patient rooms

Lighting plays an important role in healthcare, improving both the patient experience and the staff’s ability to provide the required level of care. Not only a sustainable choice, LED lighting can enhance the care environment and reduce costs by saving energy and improving operational efficiency. The latest LED technology from Airis provides a nurturing atmosphere for your patients and a dynamic working environment for your staff.

Improve experience

  • Simulate natural daylight to support patients’ sleep, mood, and recovery
  • Create a pleasant ambiance for patients and visitors
  • Enhance the well-being and concentration of facility staff

With all the research that’s been done on hospital lighting and the benefits and advantages of LED lights, it’s easy to see why they’re the best choice for healthcare facilities. Not only do they provide the color temperatures, color-rendering indexes, and controllability that hospitals need, they also save money and cause less interruptions to patient care. Just one hospital switching to LED lights can have a dramatic impact on patient health, staff satisfaction, and the environment.

Businesses urged to join the LED lighting revolution

The Climate Group launches a new campaign to convince more businesses to switch to connected LED lighting as the quickest way to cut building emissions

Businesses around the world are being urged to switch to LED lighting in a bid to cut their greenhouse gas emissions and energy bills, as part of a new campaign from The Climate Group.

Firms can realise millions of dollars in energy savings and immediately slash their climate impact by switching to connected LED lighting, the influential NGO argues, citing estimates from Signify – the company formerly known as Philips Lighting – that a global switch to LED technology could save 403 million tonnes of CO2 a year and save £94bn on energy bills.

Total annual emissions savings from LED lighting could prove equivalent to taking 265 million cars off the road.

“Improving energy efficiency belongs at the core of business strategy,” said Helen Clarkson, chief executive of The Climate Group. “Installing LED lighting immediately lowers energy costs while delivering on emissions goals. In this pivotal year for climate action, every successful, energy-smart company will make LEDs their first port of call.”

“Connected indoor LED lighting not only achieves unprecedented energy savings, it can facilitate many use cases enabled by Internet of Things,” said Derek Wright, global head of office systems and services at Signify. “Connected Lighting can do so much more enabling users to understand their space utilisation, improve performance, send high bandwidth data, help employees find spaces to work and much more. Businesses should not delay the roll-out to connected LED lighting in their buildings to ensure they take advantage of both immediate and future benefits.”

Psychology of LED lighting in retail

We often hear about the effect of retail store atmosphere on consumer decision-making. The often cited classic example is the wine store and music study; playing French music led to more French Wine sales where as playing German Music led to more German wine sales. This is a great example of research demonstrating cause and effect on consumer behaviour with statistical support to back up the claims.

Given the effect of music on store atmosphere; we can start to question what other aspects of the retail environment can be controlled to help consumers with a purchase decision? Lighting has often been thought of as task orientated and functional is now emerging as another potential variable of atmospheric influence that could shape the consumer experience.

John Flynn took the first step beyond lighting as merely a functional environmental factor and identified four attributes: bright/dim, uniform/non-uniform, central/perimeter, warm/cool light. These dimensions represented a movement beyond task performance. Lighting designers have used these attributes to get the ambiance right, for instance, non-uniform warm white lighting cast on perimeter surface areas can create a relaxed atmosphere.

For Flynn lighting was as much as an art as a science and it’s only recently that researchers have started to move towards an empiric understanding of how light makes us tick. On a fundamental level people are clearly drawn to light and so light can draw attention to products. Summers and Herbert (2001) found that more belts where picked up and touched with the addition of bright lighting than under dim display lighting. For Flynn lighting was as much as an art as a science and it’s only recently that researchers have started to move towards an empiric understanding of how light makes us tick.

We a literature scan to try and find out what the state of the research is with respect to lighting and consumer psychology and we can see this area of interest is just getting started. The majority of lighting implementations in retail design are still inferential and based around links between lighting and emotion or mood but people are starting to specifically research the direct link between lighting and retail psychology.

We did find a couple of interesting pieces of work worth talking about. First, a researcher looked at 57 clothing stores to understand if lighting played a role in evoking atmosphere and found that it was a significant factor. This might sound like an obvious conclusion but in an area lacking research, it means that other researchers have a foundation to build off. Other researchers have found that bright lights and cool colour temperature* are associated with comfort and spaciousness plus order perception. However, it looks like retailers need to be careful that they don’t go too bright as overly bright lighting can trigger anxiety and pressure in some consumers. We also need to remember these factors are highly context dependent as the preferred lighting level has been associated with the social situation in question and the type of activities, for instance, shopping, eating, socialising.

With respect to specific use cases for lighting studies, we found one particular study of note. Participants where encouraged to shop for different items and then try them in dressing rooms where the lighting direction had been manipulated. The researchers found that the lighting direction in the dressing room had a strong effect on facial shadowing and concluded that frontal lighting is generally preferred for self dressing room evaluations. For clothing retailers a consumers perspective on how the look in the dressing room has a direct impact on a purchase decision. This leaves lighting designers faced a choice between overhead and frontal lighting to opt for frontal lighting if they cannot use both.

Whilst the research of consumer psychology and lighting is only just getting going it’s an exciting time to be in this space. With the advent of ‘smart’ internet connected lighting control systems the lighting industry are certain to develop much more interest in the psychology of lighting. More robust research will help enable innovative product development to help retailers shape customer experience and optimise customer decision making.

Why offices should have LED lighting

As well as appearance, office lighting can have an impact on the way people work. Whether in an office, warehouse or retail environment, poor lighting can result in employees becoming tired and less productive.

4 key benefits of good lighting:

  1. Enhances well-being.
  2. Improves productivity.
  3. Reduces operating costs.
  4. Improves visual appearance.

Employee office wellbeing

The right office lighting is crucial. Poor lighting can have a negative impact on employee health, safety, and wellbeing. Eye strain has been reported as a leading cause of stress in the workplace. A study found 68% of office workers were concerned about the effects of the lighting on their physical health.

Business efficiency, marketing & performance expert, Andrew Jensen, said “Florescent lighting, especially, has a number of negative effects on employees, as it has been known to cause eye strain, and it is also cited as a trigger for migraine headaches. This harsh lighting also makes it more difficult for the eye to focus.”

Productivity and performance in the office

For a motivated and efficient workforce, lighting can have a major influence. Jones Lang LaSalle recently reported, “Revolutionary lighting technologies are resulting in significant gains in energy efficiency. But the biggest potential benefit from improving lighting in the workplace may be the effect it can have on productivity.” also reported a direct correlation between light levels and performance in the workplace. Referencing research, they summarise, “The right lighting can help regulate your employee’s body clock, boosting mental performance and helping your employees feel more alert and energetic. The better the light quality, the more pronounced this effect is.”

We replaced tired factory lighting at System U with new LED lighting units. In a factory environment, good lighting is imperative. The new LED light fittings are at least twice as bright, cost less than half to run and will outlast any other product available on the market. Their engineers have noticed a significant improvement.

“We have had feedback from our engineers in the workshop to say the LED lighting is a vast improvement and they are finding it much easier to work. The added bonus is that we are noticing a reduction in costs and energy consumption.”

Operating costs

We all want to keep operating costs to a minimum. How much are your office lights costing you to run? How often do you find you’re replacing light bulbs? Make a smart investment in better lighting for your office now, and save costs in the long run.

We installed LED Lights at Hambleton Primary School to replace their existing fluorescent strip lights.

“We sourced Airis Energy Solutions alongside the Green Business Fund/Carbon Trust to install a full school LED Smart Lighting system.  All our lighting was extremely outdated and was failing more frequently, at a significant cost each time.

The new lights were put in by Paul Davies, Airis’ Installation Manager, and this was a very efficient process, with all the old lighting being taken off-site afterwards.  It has siginificantly improved the appearance around school, has reduced our maintenance costs to 0, reduced our CO2 emissions and will reduce our energy consumption over time.

There is no capital outlay and the cost of the scheme is funded in part by a Carbon Trust Grant and the balance of the energy savings made.”

Visual appearance

Many interior designers are now turning to LED lighting in homes and businesses around the world. When carefully deployed, lighting can transform a room. There are many LED light fittings now available, to offer a nice stylish finish to any home or office environment.

LED lights provide brighter, natural quality lighting which lasts longer and helps reduce office overheads. If improved light levels and light quality can improve productivity and reduce running costs, LED lighting is, without doubt, a win-win solution for businesses everywhere.

How much you really save by switching to LED lights

Will LED Lights Save Money?

The most frequently asked question in lighting solutions is, “Will LED lights save money?” The answer is that LED lights consume around £80.00 of power over a 20+ year lifespan. CFL bulbs consume in excess of £120.00 over the same period and must be replaced every 5,000 hours. This gives LED lights the edge when it comes to net savings on both energy and lifespan.

How LED light bulbs save you money

The cost saving provided by LED lighting is due to two factors:

  1. LEDs require much less electricity to power than both traditional incandescent and halogen light bulbs, and energy efficient light bulbs (CFLs).
  2. They last much longer than their incandescent, halogen and CFL equivalents.

For example, a 60W halogen light bulb would be replaced with a 9W LED. That’s a reduction of 85% in electricity consumption. The LED bulb will also last for over 20,000 hours, as opposed to 2,000 hours for the halogen – ten times longer!

What about CFL bulbs? Using the same example, a 60W halogen equivalent would be an 11W CFL bulb, so the reduction in electricity consumption from CFL to LED would be 18%. A good quality CFL should last for around 8,000 hours, which is still less than half of the LED equivalent.

Calculate the cost savings of LED light bulbs

Now that we know why LED light bulbs are cheaper to run, we can now look at how you can calculate the amount of money you can expect to save by switching to LEDs.

The information you need to work this out is:

1. The wattage of your current light bulbs and spotlights.
2. The average length of time each light bulb is in use for per day.
3. Your current electricity rate per kilowatt hour (kWh, kW-h or kW h). The UK average at the time of writing is 14.71 pence p/kWh if paying by direct debit.
4. The cost of replacing each bulb with an LED equivalent.

What is LED Lighting?

LED stands for light-emitting diode which is a semiconductor light source. Originally appearing as a practical electronic component in the 1960s, they initially provided a very low-intensity light output but in recent years that has changed, LEDs can now offer an extremely bright light output and they are used in a wide range of domestic and commercial lighting. LEDs provide many advantages over traditional incandescent light sources including low energy consumption, much longer life, improved physical robustness when used in the right way (heat management and power using the correct power supply or driver), smaller size, and faster turn-on times. LED lighting also emits no UV, is flicker free and generally runs much cooler than traditional lighting.

LED lighting can be supplied with a single colour light output or colour changing light, usually referred to as RGB which stands for Red Green Blue, as it is a mix of these 3 primary light colours, which generates the vast range of colours you can generate from RGB LED lighting products such as strip lighting and panels. The single colour products, most commonly supplied in White light outputs can be supplied in various types of white. The most common white LED lighting colours are Warm White, which as the name suggests is a more traditional warm yellow light, Cool White which is a very Ice White and Daylight White which sits in between the Cool and Warm white options. Other common single colour LED lighting is Red, Green, and Blue but modern LED lighting is available across the visible, ultraviolet and infrared wavelengths.

The lighting industry is currently going through big changes thanks to LED lighting technology which has now come into its own. LED lighting is now the preferred choice of lighting for customers looking to save money in the medium to long term thanks to its reduced energy consumption and for commercial clients a reduction in maintenance costs. The market is becoming saturated with a vast selection of LED lighting products from suppliers across the globe so it makes sense to buy led lighting from a company with industry experience, that can offer the right balance of quality and price. As with all products, not all LED lighting is manufactured to the same quality level.

8 reasons why you need LED lighting in your workplace

Offices and workplaces have been slower to make the switch to LED lighting, as many still use T5 technology due to its cheaper cost. However, LEDs are getting more and more efficient and popular. This article highlights the reasons why you too should make the jump to LED lighting in your office to improve productivity, health, wellbeing, safety, energy-usage, ergonomics, and cut business costs.

1. LED Lighting is Energy Saving
LED stands for light-emitting diode and are an incredibly energy efficient source of lighting. An LED light can last 50,000 times longer than a traditional halogen light. 95% of the energy in LEDs is converted to light and only 5% is wasted as heat. LEDs are also free from toxic elements found in other lights and are recyclable. They have a longer lifespan so have lower carbon emissions and fewer lights are needed so energy consumption is reduced.

2. LED Lighting Saves Your Business Money
Switching from normal light bulbs to LED lights not only saves energy, but saves your business money. The longer life of bulbs saves money for your business as less is spent replacing them. Switching to LEDs can save your company up to 80% and keep your bills low. Lighting also improves productivity, health, and employee well being, therefore boosting your business whilst keeping operating costs low.

3. LED Lighting Improves Safety
Emergency signs use LED lighting to highlight the nearest exit in emergencies as they are clear, bright and long-lasting. High-quality LED lighting allows workers to see hazards. Office space, stairwells, and exits are all well lit for an easy and safe emergency exit.

4. LED Lighting Benefits Health
Health is a big consideration for workplace lighting as poor lighting can cause health issues such as headaches, discomfort, eye strain, dizziness, and tiredness. Bruskin Goldring Research found that 85% of workers suffered from headaches as a result of poor lighting in the workplace. Kensington Technology Group listed eyestrain as a leading cause of stress in the workplace, and stress can lead to major health issues like anxiety, depression, high blood pressure, heart problems, diabetes, skin conditions, asthma and arthritis.

The Library of Medicine National Institutes of Health found that light influences human vitality, energy, mood, alertness and work performance. LED lighting can have a positive impact on employees and boost physical, physiological, and psychological health and well-being, which enhances performance and reduces absenteeism.

5. LED Lighting Enhances Productivity
With better health comes better productivity. Productivity is an important factor when choosing the right office lighting, and there is a direct correlation between light levels and performance in the workplace. Poor lighting and lack of brightness can reduce productivity and motivation. Bruskin Goldring Research found that workers believed that improved lighting in the workplace could improve mood, increase energy levels, and enhance productivity. Cornell University found that 24% of office workers claimed poor lighting as a cause of loss of work.

This study also found, however, that LED lighting can increase productivity by 3% – 5% throughout the day. LED lighting can regulate the body clock, boost mental performance, and make employees more alert and energetic. The EU’s Lighting for People project has proven that sufficient lighting in the workplace, such as LEDs, increases productivity, and the higher quality lighting, the better productivity.

6. LED Lighting Optimises Ergonomics
Ergonomics focuses on fitting the worker to the job, not the job to the worker, and aims to find the best way to get the most from the worker and increase efficiency. Lighting is consistently rated as a workplace concern by workers as lighting can either enhance an employee’s job or limit them, and impacts mood, comfort, and performance.

Lighting which causes reflections in screens, glares, and shadows are examples of bad workplace design and negative ergonomics, but LED lighting combats this by creating different environments for workers which makes the space more comfortable for them. LED lighting can be tailored to the worker’s needs and preferences to help them work to the best of their ability and ensure optimum performance.

7. LED Lighting Enables More Worker Control
LED lighting allows different people to use different levels of lighting. It is flexible to worker’s requirements and can be adapted to each employee’s needs. With LED lighting, workers can alter the controls themselves at their desks, so each worker is more productive and happier at work, using the lighting suits them.

The rise of controls has come hand in hand with the rise of LEDs. We are working in new and different ways and mobile working and hot-desking are growing in popularity with many working in different spots throughout the day. Task lighting is becoming more important to give people easy control over their own lighting and work more comfortably and productively throughout the day.

8. LED Lighting Promotes Corporate Social Responsibility
Corporate social responsibility is a corporation’s initiatives to take responsibility for the company’s effects of environmental and social well-being. To resolve corporate environmental issues, LED lighting reduces energy and carbon dioxide emissions and is environmentally friendly.

In relation to social responsibility, LED lighting improves employee health, safety, productivity, and ergonomics. One study found that 68% of all office workers were concerned about lighting, and Kensington Technology Group state that office workers consistently rated poor lighting as the first or second work environment concern. LED lighting can ease employee concerns about lighting as improves health, well-being, performance and comfort in the workplace.

It is clear that LED lighting will benefit your workplace and business in many ways. From saving energy, cutting costs, improving safety, and improving health, to enhancing productivity, optimising ergonomics, enabling worker control, and promoting corporate social responsibility, you need LED lighting in your workplace – it’s a win-win for employees and employers alike.

Why LED lighting is so quickly becoming the norm

When it comes to technology, we are certainly used to seeing new innovations take hold, and then quickly replace the things we were using before should they offer something the older alternatives didn’t.

The flip phone was quickly replaced by the smartphone. VHS was quickly replaced by DVD, and then DVD began to dwindle in popularity as streaming services became more easily available to consumers.

The same thing is true when it comes to more domestic things, though the process is usually a little slower, as things we interact with in the home tend to be replaced less often than things like personal tech and media. Toilets with water saving flush features have become the norm for new toilet installations, for example, although many homes that haven’t replaced their bathroom suites in a number of years still don’t have them.

LED lighting has been around as an option for home use for quite some time now, but it is only really in the past five years that it has become the mainstream choice for lighting. Recently, GE, who were the main manufacturers of the older style of energy saving lightbulb, announced that they would be ceasing production of these older bulbs and focusing on LED. This is a big sign that LED is not only the future of home lighting but is rapidly becoming the present, too.

The main reason why this is only happening now is that the cost of LED light bulbs used to be considerably higher. Better manufacturing and the economies of scale that come into play when something goes mainstream have meant that LED bulbs for normal home use cost a fraction of what they used to and are only slightly more expensive than traditional bulbs. That extra cost is recouped very quickly due to the fact the bulbs cost less to run and last much, much longer.

So, now that these bulbs are within the range of affordability for most homes, consumers are choosing to switch to them when they need to replace a light. Moreover, a lot of consumers are choosing to replace all lighting inside and outside of their homes with LED, even if the lighting they currently have still worked just fine, due to all of the advantages LED has over older products such as compact fluorescent lighting or halogen bulbs.

Here are some of the advantages of switching to LED lighting:

Energy Efficiency

One of the most talked about draws for LED lighting is its energy efficiency. In an age where people are increasingly concerned with the environmental impact of the things they use in their homes, it is no surprise that a reduced carbon footprint alone is enough to drive many people to switch to LED. However, even for those who don’t list their carbon footprint as a priority in their purchasing decisions, LED’s vastly improved energy efficiency when compared to other means of lighting make it far cheaper to run, and so the reduced energy costs are another big selling point for consumers.

While the actual efficiency improvement you can get by switching to LED depends on a lot of factors, including the type of lighting you are switching from, how powerful the LEDs you need are, and what kind of energy tariff you are on, LED is the most energy efficient mode of lighting that is widely available and suitable for domestic use. This outperforms other types of bulbs that used to be dubbed ‘energy saving bulbs’.

Attractive Design Options

One of the things that prevented compact fluorescent bulbs from ever really becoming as widely used as their creators expected was that while they were more energy efficient than traditional bulbs, they also had cumbersome, ugly designs that meant that they didn’t lend themselves to a lot of design aesthetics where the bulbs are not hidden. LEDs, on the other hand, can be fashioned into just about any design you want, mimicking the look of traditional bulbs or forming spotlights, lighting tubes, and all kinds of other shapes and looks.

Additionally, LED can be made to generate light in whatever colour you want. In the past, if you wanted a coloured bulb, this was created by using coloured glass with a plain light filament inside. This would mean the light was fixed to one colour. LED can, however, be made to change colour, as well as change brightness. This is why so many ‘fun’ types of lighting like disco lights and Christmas lights have been made using LED technology for a long time, but you can also see a lot of other interesting applications of LED, such as colour changing shower lights used to give a luxurious experience in the bathroom.

Great Outdoor Lighting Potential

Outdoor lighting usually requires greater brightness, as well as fittings that are designed to withstand the elements. With LED, it is possible to create very bright outdoor lighting, including floodlighting and security lighting, which is still relatively cheap to run. The design options that come with LED technology also mean that outdoor lighting for more decorative purposes can be created with any kind of look you want.

Another benefit of LED for outdoor use is that it is low maintenance. This allows you to position your lights on parts of your house that can be a pain to reach. Eliminating the need to dash up a ladder every few months to replace a bulb. Some LED installations can last for decades of normal use before bulbs need to be changed.

Easy To Switch

Even with all of these advantages, people would still be reluctant to change to LED if this meant making major changes to all of their light fixtures and circuitry. In fact, you can simply install an LED light bulb into existing screw or bayonet light sockets without making any other changes, and if you do have an unusual lamp or light fitting, there is usually an inexpensive adaptor available that will allow you to install a normal LED bulb.

As with older light bulbs, you do have to be careful to find a bulb with the right size and style of fitting, but there is the same range available as with other types of bulb, so you don’t need to do anything more than shop for LED equivalents and switch them straight in!

There are a huge number of benefits to LED over other types of home lighting, including longer lasting bulbs, greater versatility for outdoor lighting, lower energy expenditure for the same brightness, and ease of making the switch. Since LED outperforms older types of lighting in just about every category you can judge a bulb on, it is the obvious choice when choosing new lights, and switching to LED for older lights is also a very good option in many cases.

If you are one of the many consumers who has been waiting for the prices of LED bulbs to decrease or for LED to become completely mainstream before updating your home to use it, then you should find that now is the time to take the plunge and start seeing the advantages of LED at home for yourself!
