Save energy while improving student performance based on light spectrum

The color of light emitted from a light bulb is measured in degrees of Kelvin (K) on a scale from 1,000 to 10,000. The research links below all refer to high kelvin which is in the 5000K to 10,000K range.

Dutch studies indicate High Kelvin improves student concentration and performance

The right light improves energy performance. It can also improve student performance.

Schools & Universities

Research

In the quest to save money on energy and maintenance, many schools just look at watts. Very few even begin to think on how light affects the kids working under those lights. Study after study has indicated light in the rich blue spectrum has the most positive effect in helping kids improve performance. We have linked some of them above and have many more in our library. 

Low Cost

Then there are schools who really want to save money and they specify a T8-LED light bulb with no ballast or driver. This is the lowest cost method to upgrade your lighting, unfortunately it comes with other costs. Even though you may not see it, this light flickers. Most people are not affected by it, but those that are; this is a trigger for migraines, autistic and epileptic seizures. Do you really want to put your students and staff under this light? It will save you money, but it may cost you double when you are fixing the flicker problem. Learn More

Glare and Contrast

The learning medium has changed too; smart boards, Chromebooks, and iPads are replacing books. Lighting is even more important with this new medium, now we are dealing with glare and contrast. When lighting is too bright, students at the back of the room have a hard time seeing the smart board due to poor contrast. This is common with presentations, imagine this every day in a classroom. Glare is a primary cause of eye fatigue. Your students get fatigued, the teachers start losing them, and student performance goes down. 

As you can tell from the research, EPL takes lighting seriously. A pleasant surprise for the owner is that it does not cost more to get lighting right.  By getting the science of light right, the energy savings always exceeds a simple lamp or fixture swap out. At the end of the day, the upfront cost is nearly identical and the long term savings is always greater with the added benefit of improved student performance! 

On-Site Lighting Audit

Request a lighting assessment and an EPL lighting professional will reach out to learn more about your lighting needs and answer your questions.

Our thorough, on-site lighting assessments include:

  • Complete facility lighting evaluation with room-by-room counts of existing lighting fixtures, light level readings and other detailed measurements
  • A lighting upgrade proposal based on the lighting needs for the work performed 
  • An Energy Savings Report
  • Available Financial Incentives/Rebates
  • PACE funding or leasing available
