The Kraken Hydra 2500 WRU (White, Red, UV) Macro Edition is an all-in-one solution for divers wanting to shoot both video and photos. In flood mode, the Hydra output is 2500 lumens, sufficient for underwater video. When synced to a camera via a fiber optic cable (not included), the Macro Edition will fire in a burst/strobe mode of 4000 lumens, sufficient light for a macro photo.

Dual push button controls at the top of the light provide on/off, mode switching and intensity adjustment. A lighted battery level indicator surrounds the two buttons. The Hydra light has four color modes: White, Red, Blue and Blue/Red. The White mode provides a natural, wide-angle, 5500K color lighting, Red can be used as a focusing light, and Blue can be used at night for viewing fluorescence. The Blue/Red mode is achieved by combining the red and blue beams for a sort of pinkish purple color that can be used for artistic back or side lighting. In flood mode, White can be set to 100, 75, 50 and 25 percent intensity, and the Red, Blue and Blue/Red modes can be set to 100, 50 and 25 percent intensity. The White, Red and Blue modes are also available in the burst/strobe mode. To trigger the strobe mode, the Hydra must be connected to a camera via a fiber optic cable. The fiber optic port is on the underside of of the light body. When the camera's flash is triggered, the Hydra will act like a slave strobe and fire a 4000 lumens burst.

The battery compartment is protected with a double o-ring seal, so flooding is unlikely. However, the head of the Hydra 2500 is sealed so that in the event of an accidental flooding, while the battery will likely be inoperable, the head will still function and the entire light will not need to be replaced. This also allows for easy battery switching between dives. The battery consists of three 18650 Li-Ion cells wrapped to a single cell, which is rechargeable with the included charger. The battery level indicator will be blue at 100-80%, green at 80-30%, red at 30-10% and flashing red at 10-0% charge.

The complete kit from Kraken includes the Hydra 2500, battery, charger, spare o-rings, YS mount, 1-inch ball mount, lanyard and padded carry case. Watch our short video to see the lights operation with the dual push button controls.
