How to choose the best color temperature?

Light emission characteristics of a white light source are often expressed by a "color temperature" and is measured in K (Kelvin). If you have been exposed to indoor or studio photography you will know that a 5000K lamp will get you close to natural daylight.


Office and a classroom environment often have similarities as they are places where a lot of reading and evaluation of physical items are required. It has been proven that light sources nearer to daylight give higher contrast on printed matter and therefore make it easier to read longer with less fatigue.


Many organizations arbitrarily chose 4100K because a bright white fluorescent tube has about that color temperature, this has to do with the phosphors that convert UV light from the gas discharge tube into visible light and happens to be that 4100K producing phosphors are the lowest cost to produce for the fluorescent tube manufacturers, it also helps GE and others to create a specification that produces sort of dirty white light and is outside the real daylight spectrum.


ome lighting engineers go so far as to say that daylight is acceptable lighting but if a light can produce daylight it is not acceptable as it is more than 4100K - well a child could tell you that is plain wrong.


There is however a reason for standardizing on a color temperature and that is consistent look! If more than one fixture is in an area and there were different color temperatures in use it will look inconsistent both looking at the lights and on the illuminated target area.

Therefore it is more appropriate to apply the rule that if you are changing technologies you should do this for the whole area. Also mixing 4100K LED and 4100K fluorescent is not going to work well as the LED lights will remain at that color temperature for a long time while the fluorescents will change their color temperature significantly with use.


LED phosphors generally perform better at 5000K and today's 5000..5200K LED packages have very well balanced color spectrums making them appear almost like daylight, a good light for almost any task.

What is the best flashlight led color temperature for me?

Attention, friends! The luminous spectrum of LED is different from that of energy-saving lamp. The energy-saving lamp uses three primary colors (red, green and blue), while the cold white LED (above 5000K) uses blue LED + yellow phosphor (below 5000K, red phosphor is needed). The typical LED is 6500-7000k, and the cold white light looks very "bright", Mainly because the cold white light is dazzling.


Compared with 6500k color temperature energy-saving lamp and 6500k color temperature led, due to the narrow spectrum of the latter, the color rendering index is very low, and you will feel that part of the color is not bright when you look at the object. If you work in this environment for a long time, your color discrimination ability and vision will decline! If it is in the visual development period of infants, long-term in this environment will lead to acquired red and yellow or yellow green weak or even acquired red and green color blindness!!


Some developed countries have imposed compulsory regulations on LED lighting. For example, Toshiba made in Japan has only 4000K high color temperature led lighting!


Due to the low cost of high color temperature led, it can be understood by referring to the three price differences of XML series 6500k 1a, 5000K 3C and 3300K. The cheap 6500kled just has the "dazzling" feeling, the human eye feels very bright, and the state has no compulsory standard, so many businesses purchase low-cost 6500k led.


In order to take good care of your eyes, do not use LED lights with high color temperature in your family. It is better to use some yellowing LEDs in 2700-4000k as indoor lighting. Although the color is yellow, the color rendering index is high and it will not hurt your eyes!


Color temperature is one of preference and nothing that should be legislated. There are some human facts as to how the eye perceives an illuminated object, we humans have an automatic white balance and if exposed long enough to a particular color temperature light a red-ish, blue-ish or green-ish white paper will look white to us. So rather than getting fixated that one color temperature is better than another make sure you do not mix them in the same area.


Of course, if you have a larger organisation more rigid guidance may be required. If you are retrofitting or building new office or classroom environments, you may want to consider making your new LED fixture requirement 5000K +/- 5% but specify close deviation tolerances +/- 2% within an area.

Color Temperature and Its Effect on Our Mood

Many experts have researched that lighting color can affect your mood. We also have experienced this thing ourselves. We know how our mood is on a sunny day and how different it becomes on a rainy day. The color of light plays an important role on your current task at hand too. Choosing suitable color is as important as your room's paint. These lighting colors are categorized on the basis of temp. The color temperature of a light source is measured in Kelvin and it is determined when it is illuminated. It is basically the light appearance provided by a light measured on a scale from 1,000 to 10,000. If there is a lower temperature in Kelvin, it means there is more yellow light emitted from LED Lamp. The order goes like this - yellow, white and then blue and so on. Based on the following details you can learn about how to choose the best light for your residential area.

This range is best for reading, utility areas and under cabinet lighting. Feel the warmth of these colors and enjoy your regular utilities.


Many studies show that LED Tubelights and other lights' color can affect even our circadian rhythms. According to light therapy studies, red color has the lowest impact on our brain activity. The most influential colors for our mind and emotions are white and blue light. They significantly affect the cerebral responses that control our sleep patterns and mood.
