What is RGB?
RGB stands for red, green and blue. RGB lights are equipped with 3 LED Chips. That allows individual color changes and light spectrums by combining the red, green and blue LED light. Overall there are 16 million different light colors, that can be configured with RGB LEDs.
What is RGBW?
RGBW stand for red, green, blue and white. These lights are equipped with 4 LED Chips. With the extra white LED Chip, a clear white light can be set more efficiently and precisely, because the RGB LEDs are not combined to generate a white light.
What is CCT?
CCT stands for correlated color temperature. When using LED lights, CCT stands for a controllable color temperature. The color temperatures reach from 2700 to 6500 Kelvin and can be controlled individually with the correct controller. Warm white light is measured at 2700 Kelvin, neutral white at 4000 Kelvin and daylight at 6500 Kelvin. Depending on the day time you can set a warm or cold color temperature. On one hand its recommended to set a warm light in the evening, similar to the setting sun. On the other hand daylight is more convenient in the morning hours.
