Temperature of the light – How to select it?

Temperature of the light – How to select it?

We are not talking if you get hot under the LED light. We are talking about the temperature of the light.

For example: regular (good old) lightbulb has a temperature of light somewhere between 2700 and 3000K. Which means a bit yellowish glow and this is the light most people are used to.

On the other hand, LED light is usually perceived as cold white light with a temperature of 4000K on. The cold white gives you a feel of more brightness, but some people don’t like the cold look of the light.

basic LED light spectrum

And there is also an issue with blue light. When checking the spectrum of cold white light we can see that blue part of spectrum is dominant.

The problem with blue part of the light is especially visible during the night by the time you want to hit the bed. Why?

Because blue part of the light tells your body: “Oh, it’s morning. Time to wake up.” and you want to go to sleep. Not a great combination.

So – no cold white light in the bedroom.

You can experiment with different LED lights though and see what suits you. You can always use cold white LED in rooms you don’t frequent much, if you find out that the light is a problem.

One of the more interesting takes on light are also stores. What do you want to achieve?

More homey look? Maybe use warm light.

Modern techno feel? Use cold light.

Obviously, you need to talk to designers who can advise you on selection of the light and their brightness. There are also solutions that save energy and turn on (or are more bright) when somebody comes near the display window (at the store). With such setup you can save even more energy for the light and (just a thought) use sensor to start something else too (e.g. video on the screen etc.).
