LED Office Lighting: The Best Color Temperature for Increased Productivity
For some time now, people have wanted to know more about the positive effects of LED lighting. Numerous studies have been conducted to understand the extent to which LED lighting affects the productivity and alertness of workers at work and in schools. Soldiers in the U.S. Army have even been studied to understand how different lighting affects their productivity—soldiers have shown slower response times on cognitive tasks that measure spatial and verbal memory using fluorescent lighting rather than LED lighting.
In this article, we'll tell you about color temperature and how it can positively impact people's productivity at work. We'll also tell you which specific color temperatures are best for the office. here we go!
First things first: What is color temperature?
Simply put, color temperature is measured in degrees Kelvin (K).
Color temperature describes how light appears when the human eye looks directly at an illuminated light bulb. A bulb with a color temperature of about 2700K is yellowish-white. As the color temperature increases to 3000K and 3500K, the colors start to appear less yellow and whiter. Color temperatures over 5000K appear more bluish-white.
Daylight is ideal
Here's the thing, the best type of lighting an office can use to optimize productivity is good natural lighting. Unfortunately, not many offices, or any office, have constant access to natural daylight. So the next best solution is to simulate natural light with artificial light. The color temperature of sunlight is usually between 5000K and 7000K. The color temperature of daylight at noon is 5600K, and the color temperature of daylight varies depending on the time of day and weather conditions.
To provide the feeling of daylight, we recommend using a light source with a color temperature of 5000K or higher for offices.
As you might imagine, the amount of blue light in the light source's spectrum increases with color temperature. Higher color temperatures have greater effects on mental activity, alertness, and the central nervous system.
How LED lighting affects us
Bright white light that simulates daylight improves worker performance. In addition to visually assisting people and helping them accomplish tasks they cannot do without artificial light, the brightness and wavelength of ambient light can also affect the human circadian rhythm system, biological clock, mood, and alertness.
The researchers found that daytime exposure to short wavelengths or blue light directly increases alertness and performance. Blue-enriched white light stimulates the brain, improving alertness, performance and sleep quality. The intensity and color temperature of artificial lighting can affect the body's physiological processes, including: blood pressure, heart rate variability, and core temperature.
Are fluorescent lights harmful to office workers?
For many years, fluorescent lamps have been the solution of choice for office spaces around the world. Until then, the only option was incandescent bulbs. When fluorescent lighting came along, offices were quick to adopt it because it was a much cheaper option.
There are so many scary stories about fluorescent light because when it was introduced, there were already terminology studies about its meaning. Rumors began to circulate that fluorescent lights could induce migraines and disrupt sleep patterns. There are even rumors that it can cause cancer. Let's address these three rumors.
· Fluorescent lights can cause migraines. While fluorescent light has been shown to not cause migraines, it can make people with migraines sometimes feel worse. Migraine sufferers are very sensitive to light, and bright light, such as fluorescent lights, can turn a mild headache into a full-blown migraine.
· Fluorescent lights can interrupt sleep mode. Typically, people who work in an office work during the day, then leave work before night, and then have a period of time before going to bed. For these people, fluorescent light had no effect on their sleep patterns because of the negative effects fluorescent light had on melatonin — a natural chemical we produce to help us sleep — by the time bedtime came. will decrease.
However, people who work under fluorescent lights at night and then go straight to bed may have trouble falling asleep due to a lack of melatonin. Additionally, some studies have shown that fluorescent lights can make people feel tired and sleepy during the day.
· Fluorescent lights can cause cancer. This rumor came about because fluorescent lamps were found to emit radiation. Studies have shown that the amount of radiation emitted by such lamps (roughly the same as that emitted by cell phones) is nowhere near enough to cause cancer.
Is LED lighting better than fluorescent lighting?
LED lighting is definitely better for businesses because it's more energy efficient, the bulbs last longer, and they can be dimmed as needed, so they use a lot less energy. But is LED lighting better for people who work in an office?
You have to remember that overhead lighting is not the only light source that office workers are exposed to. Some offices do have windows, as well as computer monitors, laptops, cell phones, TVs... Office work can sometimes be a bombardment of light.
Anything that helps demoralize a person will result in their work being less than perfect and will leave them feeling tired and bored. For many of the reasons above, choosing LEDs over fluorescent lights will help make your office environment a more pleasant place to work.
This can be considered a no-brainer - switching from fluorescent to LED lighting is one of the best things you can do for your business, and one of the best things you can do for the people who work for you.
