Controllers Comparison


LED illuminations can be used either in continuous operation or in pulsed (trigger) operation. An exception is made for high-power illuminations, which must be operated exclusively in trigger mode. Pulsed operation of an LED illumination reduces the heating of the LEDs since the off-time predominates. This keeps the light output constant and reduces the aging of the individual LEDs.

Long-term use of controllers saves resources, costs, and maintenance work.

The same applies to pulsed operation with double power, also known as overflash/flash/strobe mode. This mode allows for nearly double light intensity while preventing overheating of the electrical components, provided that the pulse time and duty cycle are adhered to. These two limit parameters can be found in the datasheet.

In order to operate an LED illumination in trigger mode, a controller is required. In addition to LED illuminations, Falcon offers several Light Intensity Controllers (LIC) with various functions. However, all controllers are capable of adjusting the illumination intensity and operating the illuminations in trigger and strobe modes.
