The basic unit of luminous intensity of CD (candela). Candela is one of the basic units of the international system of units.
Generally, LED lights with different colors will have different luminous intensity, and the common unit is MCD, that is, millicandela. The higher the value is, the greater the luminous intensity, that is, the brighter. This is an important indicator to evaluate the brightness of LED light strip. The higher the brightness requirement, the more expensive the price of LED light strip. This is because the price of high brightness LED chip is too expensive, and the higher the brightness, the more difficult the packaging.
