Benefits of LED Lighting for Educational Facilities
- Jul 23, 2019-
LED lighting can increase alertness levels among students and improve overall facility safety and security, while reducing maintenance and utility costs and electricity consumption and contributing to the eco-friendly “green” environments that schools at all grade levels strive to achieve.
Recent research has shown that student alertness and overall performance is directly affected by the nature and conditions of lighting in an educational facility. Lighting color is objectively measured by “color temperature”, which is effectively a measure of the levels of different color wavelengths of light generated by a light source. Students react more positively when classroom light is at a color temperature that includes more of the blue wavelength light that is found in higher light color temperatures. Unlike fluorescent lighting that lacks significant amounts of blue wavelength light, LED educational lighting can be tuned to include more of that spectrum. LED lighting can also be adjusted during the day to generate different wavelengths that more closely match both students’ and educators’ natural circadian rhythms, thus improving everyone’s overall performance.
Education facility athletic fields will realize substantial improvements from LED lighting. LED’s generate light that is closest in color rendering index measurements to natural sunlight, thus improving visibility for athletes in both indoor and outdoor playing surfaces. Student-athletes will see fast-moving baseballs, hockey pucks, and tennis balls much more clearly and distinctly under LED lights. Sealed LED fixtures are also particularly useful for swimming pools, where light fixtures are under constant stress from high humidity or corrosive chlorine.
Safety is an omnipresent concern for all educational facilities. Educational LED lighting systems can be configured to reduce or eliminate dark spots and shadows in both interior and exterior educational campus spaces. LED lights also have a better color rendering index than fluorescent or incandescent lighting. The higher index makes it possible to see fine details and contrasts that would otherwise be lost under traditional lighting.
Like many commercial and industrial operations, educational institutions are under constant pressure to produce better results with fewer resources. LED lighting generates the same or better illumination with less than half the electrical energy input required by traditional lighting sources. LED bulbs also provide peak illumination for more than 50,000 hours, and in some cases up to 100,000 hours of continuous use. Funds that would otherwise be spent on utility and maintenance costs can be allocated to other uses that more directly benefit students and teachers.
Unlike fluorescent lamps that include mercury, LED lamps and fixtures include no hazardous or toxic substances. They can be disposed at the end of their useful lives with no concerns over hazardous waste disposal or contamination of landfills. Because LED lights consume substantially less electricity, educational facilities that are under pressure to lower the environmental impacts of their operations can reduce their reduce their carbon footprints by installing LED lighting.
