Light is an essential aspect of our lives. Its value cannot be understated. The presence of light enables us to carry out many day-to-day activities. Light allows us to see and therefore read or carry out any other activities that require vision. Light is also crucial in the vegetative growth of plants. Plants utilize sunlight to carry out photosynthesis which is the basis for plant development and uses multiple pigments to absorb light and make food. Artificial light sources can be used to provide light for plants. All the light sources are categorized by how the light appears to the eye. Most grow lights contain LEDs in multiple colors. As such, they have specific wavelengths and not every wavelength. There are, therefore, differences between the light. It is an essential factor when selecting the type of light to use. Here are a few differences between white light and yellow light.
The color temperature
Correlated color temperature (CCT) is a scale that shows the level of the light of color. You can determine how much blue light is in the morning you are exposed to using the value you get. The scale usually ranges from the warmest light of 1800K to the coldest one, with the highest amount of blue light that reaches 6500K. There are three basic kinds of light with different color temperatures. They include the following.
- The warm light of between 2500K and 300K will help you relax when you are reading and rest better after you are done.
- The natural light of between 4900K and 6500K is always the best option for eyes that allow you to work comfortably.
- The cold light of 6500K will offer you an excellent brightness level and improve your overall attention.
The cold blue light with the highest correlated color temperature is the best option for staying awake and alert during working hours. However, if you want to relax and read at night without interrupting your sleeping cycle, you must pick out the color temperature below 3000K.
Differences between warm and cool light
Studies indicate that most people find the warm light more comfortable for their eyes while reading but complain about the brightness level at the same time. The following are some of the different light types you are exposed to during the day. Do not forget that blue and white lights are sometimes considered in the same category.
Yellow light is more relaxing for your eyes and offers a pleasant feeling of being a cozy, friendly place. Moreover, it is an excellent option for reading and finishing tasks that require mental stability. You should always check Grow Light Info and install yellow lights in spaces where you often relax and read, such as your bedroom and living room. One of its primary benefits is that, unlike cold light, it will not harm melatonin production in your body. Therefore you will be more comfortable and sleepy with yellow light since your brain connects it with the sunset and perceives it as nighttime.
White light is considered cold, intense, and direct. It helps you focus and concentrate during the day, making it an excellent solution for workplaces and commercial areas. You might also want to use it in your household, especially in the bathroom, kitchen, and office room. Cold light will help you improve your learning performances since the areas are not spaces for relaxing. You can pick out a yellowish-white light below 3500K if you find out that the white light is too harsh for your eyes. Also, modern LEDs are equipped with an adjustable correlated color temperature. You should be aware that the light can improve your performance only when exposed to intermediate CCT. Lights with too high levels on the scale will make you alert, thus decreasing your performance. Also, LEDs can leave you feeling tired and irritated at the end of the day since they emit short wavelengths that are harmful in the long run.
Bluish cold light is always above the level of 5000K. Unfortunately, we often use too much blue light in the modern world through television screens, cell phones, computer monitors, and 6500K light bulbs. Production of melatonin in your body will decrease if you are exposed to cold white or blue light for one hour at night, delaying sleep time for up to three hours. Prolonged exposure to blue light is harmful and can cause permanent eye damage.
Nowadays, there are many kinds of bulbs in the market. Therefore, you can choose the right one for each room in your house or workplace, depending on its purpose. However, intelligent bulbs offer more flexibility. Instead of purchasing bulbs specific to each room, you can install them all over your home and change the light color as desired.
