It can be approximately considered that IF is proportional to VF. See the table for the electrical characteristics of the current major ultra bright leds. According to the table, the highest IF of the current ultra-bright LED can reach 1A, while the VF is usually 2 ~ 4V. Since LED light characteristics are usually described as a function of current, rather than voltage.

The LED brightness, Cd (candela), the basic unit of luminous intensity, candela is one of the basic units of the international system of units. General LED light belt different colors will have different light intensity, the common unit is MCD, that is, millicandela. The higher the value, the greater the luminous intensity, that is, the brighter. This is an important indicator to assess the brightness of the LED lamp, the higher the brightness requirements of the lamp with the more expensive.
