The Kraken Sports Hydra 2500 V2 Underwater Light utilizes a single-cell 26800 battery, making it significantly smaller than the first model, and the battery has a charging port for the included USB Type-C cable, so there's no need for a charging cradle. Output levels include a 2500-lumen flood beam and a 1500-lumen spot, with an auto-flash-off feature for focus lighting. Ball and YS mounts make it easy to mount the light on most trays, and the Hydra 2500 V2 is compatible with Kraken's GL01 Goodman Glove.
