It's a video light that works like a strobe: the Sola X Video Hybrid 10,000 Lumen Underwater Video Light from Light & Motion emits a bright, sustained beam for capturing video content, but it can also issue bursts as fast as 1/200th second for photos. The beam angle ranges from 115° to 12° with dry-swappable optics. This 328' depth-rated light emits up to 10,000 lumens continuous and 20,000 lumens peak burst with no distracting hot spots or harsh edges, regulated for consistent performance throughout the charge, and it can even stay in continuous video mode while triggering bursts for photos. You'll need a fiber optic cable from your camera or housing to use the flash-style bursts.
The Sola X Video Hybrid can provide 15,000 full-power bursts on a single charge. Charge status indicator lights show how much power you have left. Continuous light runtime ranges from 40 minutes to 12 hours depending on output level. There's a lockout mode to prevent accidental activation while in transit and an SOS mode in case you run into trouble.
