LED forward current is typically 20mA per diode at 1.7V drop for red emitters
Laser/light intensity is linear with respect to forward current through the LEDs. The specified forward current (I_led) is typically 20mA per diode, and the LED voltage drop (V_led) is typically 1.7 volts for red emitters (Eq 16).
