RGB vs. RGBW: What’s the difference and which one is better for my illuminated signage?

For years, RGB light-emitting diodes (LEDs) have been the standard for high-quality illuminated signage because of their vibrance and millions of customizable color options.

 RGB – red, green, and blue – are mixed to create a certain degree of brightness depending on preference with said brightness increasing through additive mixing of the diodes. While RGB has produced incredible signage and is still useful for certain applications, the colors emitted lack a certain warmth or pure white tone.

Enter RGBW.

What is RGBW light and how does it work?

The ‘W’ in RGBW stands for the white LED that combines with red, green, and blue to create a singular light source. The white LED in an RGBW system can be either a warm white LED or a cool white LED, depending on the desired color temperature. Warm white light has a yellowish tone, like traditional incandescent bulbs, while cool white light has a bluish tone, resembling daylight. 

You may be asking yourself, why is white LED needed when the RGB LED can produce a white-like color with a 1:1:1 ratio? While this ratio does create a whiteish color, these three colors alone cannot produce a pure white light; they can only produce a color like white by fading the color gray. This kind of false white light can come across as hazy or murky, creating low visibility and often a poor visual experience for the end user.

With the inclusion of white, RGBW LEDs can achieve more color richness and accuracy, thus producing a “full spectrum” effect.

What are the advantages of RGBW light?

Because of the white LED chip inclusion, RGBW lights are favorable for lighting projects and signage with more precise requirements and/or those who are seeking a more energy efficient cable solution.

As previously stated, because of the inclusion of a white LED, RGBW systems produce higher brightness levels and increased color intensity, which allows for amplified illumination, increased color precision, and heightened visibility. Because the white light emanating from an RGBW cable is cleaner, this is a more comfortable visual experience than that created by an RBG system.

RGBW LED light is also more energy efficient than its RGB counterpart. RGB LEDs have lower brightness than RBGWs, which means that a larger LED quantity is needed if/when more brightness is needed. This not only increases energy consumption but manufacturing costs. Since RGBWs already operate at a higher brightness because of the white light inclusion, this cuts energy needs and has a more positive effect on your signage’s bottom line.
