SeaLife Sea Dragon 3000F Auto Light Head

The SeaLife Sea Dragon 3000F Auto Light Head is a photo-video dive light that produces 3000 lumens of white light in a 120° beam (90° underwater) plus 180 lumens of red light from two red LEDs, and it is depth rated to 330 ft (100 m). It uses a BridgeLux Gen 7 Vero COB LED Array paired with two Cree XP-E red LEDs, runs on a removable 7.4V, 3400 mAh Li-Ion battery, and includes Auto Bright and Auto Flash Detect modes for underwater photo and video work.

Who it is for

This light head is built for underwater photographers and videographers who want a single, expandable video light for their camera rig. Its Auto Bright mode automatically adjusts output from 300 to 3000 lumens based on subject proximity, and its dual red LEDs let divers navigate at night or in low light without disturbing light-sensitive marine life, with the option to set the red LEDs to auto flash/strobe mode as well.
