This is the Zylight Z90 LED DV Kit. The Z90 head packs 230 Hi-leds (high-density light emitting diode) into 1 square inch panel which produces a remarkably soft 60° beam.
The 1-100% dimming head offers almost unheard of control of light quality via 3 output modes. White Mode allows selection of 3200K or 5600K white light, while Color Mode enables the user to tweak the red/green/blue hue and adjust the saturation of it. In Gel Mode the Z90 outputs white light with color temperature control from 2500K-9000K as well as +/- green color correction control.
Built-in ZyLink technology allows ganging multiple units together using simple communication and function control as if they were a single unit, from as much as 30' (9 m) away.
The Z90 has (2) 1/4"-20 sockets for mounting onto the camera or light supports using dedicated Zylight accessories. Included in the kit are:
Accessory Adapter: Allows the use of popular sized 3" (7.6 cm) light shaping tools like soft box speed rings and barn doors, to the front of the light.
Lithium-ion Battery: The battery features 14.8V high-performance Lithium-ion cells, a 4-stage LED power gauge, protection circuitry and D-Tap (Anton Bauer) connector. It provides over 3 hours of power to the Z90.

Long D-Tap Cable: Provides power via optional professional (12, 13.2, 14.4V) battery accepting Power Tap (Anton Bauer Style) cables. The 2-pin, 40" (102 cm) coiled cable extends to 80" (203 cm) and features a twist-lock DC plug.
