Understanding Colour in LED Strip Lights: CCT, CRI and Beyond

How Important Is The Color Rendering Index Of LED Strip Lights? - Custom LED  Strip Manufacturer From China

Most people would be well aware of the fact that LED strip lights come in various colours, hues and shades of whites. Just to make it clear, among the options available, statistically, white light has been found to be not just the most popular option, but also the most useful when it comes to both indoor and outdoor (waterproof LED strip lights) lighting applications. 

Before moving on, it would useful to understand that the metrics used for describing different shades or even the quality of white light are colour temperature (CCT) and colour rendering index (CRI). 

To present a slightly better understanding of CCT, it is a measure of how “cool” or “warm” the LED colour appears; to add to the perspective the subtle light emitted by a conventional incandescent bulb provides a low colour temperature measured at about 2700K whereas the colour temperature of natural daylight is generally measured as about 6500K. In contrast colour rendering is a measurement of the accuracy of colours as they appear. 

For example, under low CRI, the colours would seem distorted and quite indistinguishable whereas under high CRI, the light would make objects appear the same way they would appear under proper light sources such as natural daylight. This feature is available for both indoor and waterproof LED strip lights. It is due to the adjustability of high-quality LED strip lights of hues and temperature that has made LED strips as popular as they are. 

Especially with multi-colour LED strips, users are able to create accented and theatrical lighting rather easily. Both regular and waterproof LED strips offer colours that span across the entire visible spectrum which in essence are blue, violet, green, red, and amber – additionally infrared and ultraviolet. When it comes to coloured LED strips, they come in two varieties which are fixed single colour strips and colour changing strips. 

Basically, single colour LED strip lights only emit one colour, whereas colour-changing LED strips deliver multiple colours on a single LED strip with the most common strip offering RGB (Red, Green and Blue) which allows users to mix the colours at will to produce any desired colour. Some white (single colour) LED strips offer dynamic control systems for colour temperature tuning which enhances aesthetic potential significantly. 

Creating Ambience with LED Strips

The possibilities that LED strips offer are immense; however, it is recommended that a little due diligence is done before buying LED strips and installing them. For instance, the colour of the walls, flooring and even the ceiling and fixtures should be taken into account before choosing to buy single coloured LED strips. 

To be safe, it is advisable to consider multi-coloured LED strips that come with white, this would allow the user to try out various colour combinations for the environment until the user is satisfied when the light output matches the environment and the desired ambience is achieved. 

Buying and installing single-coloured strips could be risky simply due to the fact that sometimes-imagined visuals could differ from actual visuals greatly.
