INON INC. is pleased to announce official release of the compact LED flashlight "LF1300-EWf" on September 10th, 2017. The "LF1300-EWf" offers shutter-linked AUTO-OFF function in sync with flashing from either built-in flash/external strobe, wide 100 degrees underwater coverage thanks to its optically designed dome lens and powerful 1300 lumen from its handy yet durable body. Best suited as a focus light to assist your underwater photography/videography.
●"Shutter-linked AUTO OFF" function
On-board incident light sensor detects flashing from built-in flash/external strobe to trigger this feature to shut off the light in sync with the shutter release and turns ON again automatically to avoid exposure of the light itself on an image or backscatter by not illuminating suspended particles.
"Shutter-linked AUTO OFF" function is controlled by the red "Selector Ring LF". You can use the function for still images or deactivate "Shutter-linked AUTO OFF" function to use the LF1300-EWf as a video light to avoid unintentional cut-off by neighbor’s flash.
Cut-off time of this function is only 0.2 seconds not to lose your subject when using this function.
