This is a complete Novatron 63V6003C 3 Head Pro Kit. It provides a maximum of 600 watt/seconds of stored power. The flash heads have built in reflectors, umbrella mounts and tilt adjusters.
The Heart of the Novatron system is the power supply. It's function is to take AC line power and store it in a bank of capacitors. This stored energy can be discharged quickly and intensely through one or more flasheads. Novatron packs are extremely small for the amount of power they store.
The 2140C Lamphead contains the controls to operate at full power or to ratio the power and modeling light down to 2 f/stops from full power. The 2110C can be switched down 1 stop.
Completing the kit are white umbrellas, light stands to support the heads, and a soft padded nylon case for easy storage or transport.
