We cannot live without light. One cannot overestimate its importance. In our day-to-day lives, light allows us to perform many tasks. In order to read or do any other activity that requires vision, we need light. Plant growth depends on light as well. To sustain life, plants use sunlight for photosynthesis to produce food by absorbing light and modifying pigments.

Plants can benefit from artificial light sources, Click here and start growing plants at home. According to how the light appears to the eye, all light sources can be classified. LEDs come in different colors in most grow lights. Thus, specific wavelengths of light are present in them as opposed to all wavelengths. Therefore, other lights have different properties. When choosing a light, it is essential to consider this. White light differs from yellow light in a few ways.

Correlated color temperature (CCT)

It shows how much light color has in relation to the color temperature (CCT). Using the value you get, you can determine how much blue light you are exposed to in the morning. There are typically three levels of temperature ranging from 1800K to 6500K. The coldest light is 1800K, and the warmest is 1800K. Different color temperatures correspond to varying types of light.

Below are a few of them.

  • While reading, a warm light between 2500K and 300K can help you relax and rest better.
  • Whenever possible, natural light that is between 4900K and 6500K will be the most beneficial for your eyesight.
  • You will have excellent visibility with the cold light of 6500K, and your attention will improve.

Working hours are best spent with a cold blue light that has a high correlated color temperature. It is vital to pick a color temperature under 3000K if you want to read comfortably at night and not interrupt your sleeping cycle.

A comparison of warm and cool lighting

According to studies, most people complain about the brightness level but prefer the warmth of the light when reading. Following are some examples of the various kinds of light we are exposed to all day long. White and blue lights can sometimes be considered the same type.

The yellow light

Yellow light is soothing and creates a feeling of coziness and friendliness. Moreover, it is a good option when reading and finishing tasks that are mentally demanding. In your bedroom and living room, where you often relax and read, you should install yellow lights. The main benefit of its use is that it will not harm your body’s melatonin production, unlike cold light. As your brain associates yellow light with the sunset, you will be more comfortable and sleepy as a result.

Luminous white light

Cold, intense, and direct are the qualities associated with white light. This is a great solution for workplaces and commercial settings since it helps you focus and concentrate during the day. Besides the office, the bathroom, kitchen, and kitchen area are also good places to use. Due to the fact that these are not spaces for relaxing, cold light will help enhance learning. The white light may be too harsh for your eyes if it has a yellowish-white color temperature below 3500K.

In addition, LEDs come with adjustable color temperatures. As a result, it is essential to know that only lights of intermediate CCT can enhance your performance. When the lights on the scale are too high, you will be alert, which will affect how well you perform. In addition, LEDs emit short wavelengths that are harmful in the long run, leaving you feeling tired and irritated.

An indication of blue light

Blue light is always higher than 5000K. We are exposed to too much blue light across a wide range of devices, such as televisions, cellular phones, computer monitors, and 6500K light bulbs. A single hour of cold white or blue light exposure lowers the body’s melatonin production, putting you up to three hours behind schedule in terms of sleep. Blue light can damage the eyes permanently when exposed for a long time.

Final thoughts

Bulbs are available in many different varieties today. Depending on your house or workplace’s purpose, you can select the right one. A more flexible option, however, is the use of intelligent bulbs. By installing multiple light bulbs throughout your home, you can change the light color as you please without buying individual bulbs for every single room.
