1. Millicandela is a unit of measurement for the light output of LEDs. Candela is one of the seven base units of the International System of Units. It is a unit of Luminous Intensity (I), or Light Power per Steradian (SR), while steradian is a unit of 3D cone angle with which the projected area of 1 steradian over a sphere with a 1m radius, is 1 square meter. One thousand millicandela equals one candela or approximately one candle power.
2. Pulse width @ 1 kHz, 10% duty cycle
