AOI UCS-Q1 Ultra-Compact Strobe Q1 

Important Note: This Strobe requires 2x 18650 Batteries and a Battery Charger to function. Batteries are not included and must be purchased separately.

Product Details

The control panel of the UCS-Q1 is kept simple with just two buttons and a single knob. The knob controls the power setting; the maximum brightness setting is number 7 or the equivalent of Guide Number 22. Just adjust the brightness of the strobe to match the exposure of the camera. The strobe has a very useable beam angle of 85 degrees with the diffuser on.

The left button activates the continuous light function, which has three power settings. The different power settings can be obtained by cycling through the button. The highest setting is 700 lumens which is bright enough for macro shots or close-up video. The continuous light also works as a focus light, allowing for faster focusing and determining the desired strobe position. The buttons and knobs are clearly labelled – making it easy to control, even with gloves on.

The battery compartment is secured with a screw-on cap that is sealed with two o-rings to prevent accidental flooding. Should the battery compartment flood, it does not affect the electronic compartment as the two are kept separate preventing a hefty repair bill. The strobe is powered by two 18650 lithium batteries, which offers up to 2000 flashes on a single charge and provides consistent power delivery, even at low levels. The strobe is equipped with power stand-by and auto power-off features to conserve power and increase the lifespan of the strobe. 

Available in Black or White, please notify colour when placing your order.
