When overdriving LEDs, a negative effect is a significant heat buildup. To avoid causing irreversible damage to the LEDs, sufficient time must be allocated for cooling down. This time is determined by the duty cycle, which is the ratio of the ON time to the entire period (ON+OFF).

For STROBE operation, a maximum duty cycle of 10% is defined:

There are two different methods for overdriving:


Overdriving by applying a higher supply voltage. This method is supported by the PSA power supply and the LIC strobe controller. The two devices provide up to 48V output voltage to the lights.


The overflash is achieved by applying a higher current. This method is supported by the fact that the lighting is also available without a series resistor. In general, this method is suitable for professional users.
