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 with#7  the maximum power and equivalent of Guide Number 22. Making the UCS-Q1 a manual function strobe means that when used with an automatic compact camera, it is easy to control the flash output for every shot and nail that perfect image. 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 controlled by cycling through the button. The highest setting of 700 lumens is bright enough for macro shots or even as an underwater torch on a night dive. 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, this feature will prevent 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.

If you are into Macro Photography a specially designed Snoot is available to help concentrate the strobes flash and highlight your subject.

AOI also offer a Strobe Starter Kit to help mount the strobe to a hotshoe on an underwater housing.
