The updated version of the popular "F" series. "G" heads have an improved clamping system for more reliable braking, and stability when using the head with larger, heavier accessories, such as softboxes. The included flashtube protection dome is now better-protected with a redesigned locking bayonet device. Voltage level is automatically sensed, modeling lights are changeable for 220V. This head will fit on almost any third party lightstand, eliminating the need for the Broncolor adapter. The familiar features of light angle focusing, 1600 w/s of consistent power, standard Broncolor Bayonet reflector mount and umbrella holder, and cooling fan are still built in.
