This is the Zylight Z90 LED Double 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 (2) Z90's and 2 each of the following accessories:
Worldwide AC Adapter: Accommodates voltages from 100-240VAC and features a 6' (1.8 m) DC power cord with twist-locking collar and a detachable 10' (1.8 m) AC cord. The 2-prong US plug requires an appropriate adapter when used outside North America.
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.
Tilting Stand Adapter: Threads onto the Z90 via its 1/4"-20 thumbwheel screw. The adapter tilts approximately 100° and mounts on a 5/8" (16 mm) stand stud.
Zylight 5/8" (16 mm) Stud Mount: The lightweight, brushed aluminum stud fits into any griphead, stand or accessory with a 5/8" female receiver. The 1/4"-20 screw threads into either of the Z90's mounts. A hole in the shaft facilitates tightening and loosening.
Barndoors: Compatible with the Z50 and Z90, barndoors help flag-off, direct and control the beam of light. They are fabricated from durable metal and painted matte black. Mounting the barndoors requires use of the (ZYAZ90) accessory adapter (sold separately).
