No matter, what’s your purpose of using the LED, you must know the difference between warm and cool light.This has become even more important these days when there’s a growing demand ofLED lights. In fact, temperature is one of the deciding factors of buyingLED andthesellers willalso come up with terms such as "3000K vs 4000K" whilepitching about their product. So, here’s a detailed explanationof the Warm White and Cool White LEDs as well as the ideal situations when you should use them.

Let’s Talk about LED Colours

The temperature of LED is closely related with the colours of LED Light.Technically, LED chips are designed to emit a specific light colour and from the red, blue, yellow, and pure white light spectrum.This is why LED technology is applied to various applications.The terms warm white and cool white are basically the references to low and high end of this white light colour spectrum.

The difference lies in the term ‘Colour Temperature’ i.e. the colour of the light. According to that, warm lights emit a colour that is close to natural red colour while the cool light appears somewhat bluish. To differentiate between the two, the Kelvin scale comes in handy. The Kelvin scale (determined by letter K) is basically the standard of measuring light in numerical values. So, when you are going to purchase the LED light, make sure you see by a ‘K’ on the packaging. If the range of the number lies between 2700-3000K, then it is considered to be a warm lighting. If the value lies between the ranges 5500-6500K, then it’s a bulb with cool light. Anything in between is considered as a natural light bulb.

How exactly is Warm and Cool Lighting used?

There’s an optimal way to use the warm and cool lights depending on colours.Warm light feels more natural in the evenings as it has a more relaxing feel to it. It is completely in line with the human circadian-rhythm in the evening, and helps your weary nerves to wind down and prepare the body for sleep.

Cool lighting, like LED Ceiling Lights, on the other hand induces alertness and energy. That’s why it’s perfect for indoor lighting during the day. But on using cool light in the evening can interfere with the body’s natural clock.

Where These Lights are Used

Ideally, warm LED bulbs should be used in living spaces such as bedrooms, living rooms, hallways and places where you spend some time for cosy retreat. Cool lighting on the other hand is perfect for kitchens, bathrooms, study rooms and also for retail spaces, where much of the activity is involved. For an experimental approach, you can even mix and match warm and cool lights in the same space and enhance the aesthetics.

The Takeaway Point

A detailed knowledge about the colour temperatures help you get better ideas and makebetter decisions while purchasing the LED lights. But go a little experimental keeping your personal preference is mind to enhance the aesthetics.
