The hybrid Advanced Illumination Brightfield/Darkfield LED Ring Lights offer a level of versatility not previously available. The darkfield and brightfield illumination is provided by two independently powered rings of LEDs.
The strobed models' flash duration is dependent on a trigger signal or potentiometer setting. The duration of the strobe can be adjusted from 30 - 300μs via a knob located in the back of the unit. Trigger input signal is CMOS/TTL compatible. The maximum trigger frequency is 30Hz.
