 In addition, each colour beam can be used as an AFO focus light, which automatically shuts off when the unit’s electronic flash sensor detects a flash. With a wide 100-degree beam angle for greater illumination, the flood and red modes have adjustable brightness levels of 25%, 50% and 100%. When used in areas with ambient temperatures above 50°C, the brightness is automatically reduced to 20% to protect against overheating. 

The Marelux Lumilink, which can be installed on the fiber optic port of your camera housing, both encrypts and amplifies the signal received from your housing’s internal optical flash trigger. It then transmits it via optical signals. Capable of extending the range of optical signal transmission, the Lumilink has an effective transmission distance of 2m underwater and an optical signal emission angle of 160 degrees. Made of anodized aluminium alloy, it measures 82mm in width, 70mm in height, and 64mm in depth.
