Weefine WF103 Smart Focus 2600 Focus Light
The Weefine WF103 Smart Focus 2600 is a compact, high-intensity underwater focus light engineered for underwater macro photography, video shooting, and nighttime dives. It is part of the broader line of Weefine lights, known for intelligent functionality, multi-color output, and reliability in extreme conditions.
With a maximum output of 2600 lumens from a single LED array, this Weefine video light enhances autofocus speed and accuracy in dim or turbid underwater environments. It features multiple beam modes—including white, red, blue, and UV—making it suitable not just for focusing, but for video fills and creative fluorescence photography.
The light uses a smart sensor-based auto shut-off function, which turns off the beam when a strobe is detected and reactivates immediately after. This ensures consistent exposure without hot spots in flash photography. It supports multiple operation modes (constant, strobe detection, red/blue/UV), with output levels adjustable across five power steps.
Rated to a depth of 100 meters (328 feet), the Weefine Smart Focus 2600 is ideal for advanced divers, technical photographers, and underwater filmmakers seeking compact and multifunctional focus lights that integrate easily with camera rigs and arms.
