MCD Electricity Abbreviation

Millicandela

In the field of electricity and lighting technology, MCD stands for “Millicandela.” It is a unit used to measure luminous intensity, specifically one-thousandth of a candela (cd), the SI base unit for brightness. Millicandela is especially useful when describing the brightness of small light sources, such as LEDs. For example, an LED labeled as “2000 MCD” emits 2 candela of light. People might search for this term using phrases like “MCD LED rating,” “millicandela vs candela,” or “LED brightness units.”

MCD values are important when selecting lights for displays, indicators, and consumer electronics. Higher MCD numbers typically mean brighter output, though the viewing angle also matters—narrow angles concentrate light and make it appear brighter. Engineers and designers rely on MCD measurements when choosing components for devices that require visible light in low or high ambient conditions. Related terms include “luminous intensity,” “brightness rating,” and “light output measurement.”
