A brighter futureCreate a better learning environment with LED lighting
The future is shaped by choices we make today. This is especially true in our schools. By upgrading the lighting to high-quality LED luminaires, you'll help provide students and teachers with an environment where it's easier to learn, and easier to thrive.
Why is quality lighting in schools so important?
The light in our environment affects our energy level, mood, circadian rhythm and health. The right amount of good light makes it easier for students and teachers to get the most out of each day.
Students with enough energy find it easier to concentrate and maintain focus throughout the day. This in turn leads to improved motivation, and makes it easier to take part in all types of learning activities.
Energized students that feel a sense of mastery are happier. The same applies to teachers and staff, and this contributes to a better learning environment and a better relationship between students and teachers.
How do you create good light?
The right amount
The right amount of light is essential to maintaining students’ well-being and ability to focus. How much light is needed depends on many factors, such as type of activity amount of natural light and grade.
When using a blackboard, there should be enough light on the teacher and the blackboard. This ensures that everyone can follow the class and makes it easier for the teacher to maintain contact every student. The ability to dim the lights helps prevent glare and reflections, and is key when using a projector or screen. When working in groups, there should always be adequate light on all work surfaces.
The right amount of light is not always enough, the light should also be evenly distributed. Uneven, or too focused light creates unwanted shadows and unpleasant reflections & glare in bright surfaces.
Luminaires with micro prismatic optics (a diffuser) provides even, pleasant light by diffusing the light as it exits the fitting. Diffusing the light means that it’s spread in in multiple directions and reflects of walls and other surfaces, rather than only going directly from the soure to the work surface. Light falling on the work surface from many angles helps eliminate shadows and glare.
The optimal color temperature
Color temperature is measured in Kelvin and indicates how white the light is. The higher the number, the whiter the light. Color temperature has a significant impact on our well-being and energy level.
Light with 2500 or 3000 Kelvin has a yellowish, warm color quality that is often perceived as pleasant. Light with 4000 Kelvin has a whiter, more neutral quality that helps keep us awake and able to focus for longer periods of time. What color temperature you should choose depends on factors like the type of room, access to natural light and preference.
Accurate color rendering
Color rendering, or RA, is a measure of how well the light renders natural colors in the environment. In high quality light, objects and surfaces should have color shades very close to those produced by natural light.
The ability to render colors accurately especially important in lower grades, where colors play a large part in the learning experience. Proper color rendering is achieved by ensuring that the light contains all colors in the spectrum. Indoors, a RA of 80 (on a scale from 0 to 100) is considered good.
Glare can be caused by direct light or by reflections from other surfaces. If too much light enters the eye, this causes strain, discomfort, exhaustion and headaches over time. Glare and reflections in screens may make it hard to see at all.
The best way to avoid glare is to provide the right amount of light with proper distribution and to use micro prismatic optics that diffuses the light. Diffused light is less intense and prevents glare and reflections in white or shiny surfaces. Keeping glare and reflections to a minimum has become even more important as computer and tablet screens have become a vital part of many classes.
Old light sources, low-quality components or malfunctioning power supplies often to lead to flickering lights. Both perceptible and imperceptible flickering has a negative impact on our well-being and ability to focus.
All products that are to be used in school buildings must comply with strict standards for flicker. Complying with these standards throughout the lifetime of the product is achieved by using high quality components and the latest production and testing methods.
Efficiency + longevity - maintenance = a good investment
Efficiency is determined by how well a fitting transforms electricity to light, in other words, how many lumens you get out for every watt that goes in (Lm/W). Modern LED fittings use significantly less power than other light sources and even previous LED generations. There’s also a big difference between good and not so good LED products. Replacing old lights is a very efficient way to reduce power consumption and expenses.
While it’s true that LED products are more expensive, the superior efficiency ensures that the investment quickly pays for itself. For most of the products expected lifetime, the reduced consumption leads to pure savings.
Quality LED products should provide the same high-end light quality for at a minimum of 50.000 hours, and should not require maintenance. The product will not stop functioning when it’s minimum life expectancy has passed, but the light quality may slowly begin to decline. A long product life mainly depends on the quality of the components, and on the LED modules not becoming too hot.
With a life expectancy that approaches 8 hours of daily use for 17 years, is the potential for significant savings is self-evident. Replacing other light sources, old fittings or low-quality fittings is one of the most efficient ways for schools reduce power consumption and costs.
For the installer
Simple mounting & a good result
As an installer, choosing the product that provides the best light and the highest efficiency is not your only concern. In addition to ensuring a satisfied customer, you also want to complete the installation as quickly and as painlessly as possible.
The Ledge® product family consists of a complete range of indoor fittings specifically designed combine a simple installation with high-end light quality and efficiency. Elegant, minimalistic design features make it possible to create a common visual identity throughout the building.
Kurland Elementary School
At Kurland Elementary School, classrooms, activity rooms and the kitchen have been upgraded with Ledge® Surface fittings. Students, teachers and installers are all very happy with the result.
“We all agree that this is a good product that works well. Proper lighting is important for us. It creates a better learning environment” – Anne Berg, manager.

“One of the best things about this product is that you first mount the lightweight mounting plate, and then simply click on the fitting. This really lowers the strain on your neck and shoulders. There’s also enough room for the mounting brackets behind the lamp, and the position of the fitting can be adjusted by a few centimeters on the brackets. The fitting is easy to mount, nice to look at and the quality is very good.” – Jan-Erik Midsundstad, EDA – Installer.
