The Dedolight 200W Daylight Tungsten Soft Light System with 3ft Octodome (SYS-200S-OCT3) is a single function light head exclusively for use with four different types of soft boxes. Since the actual light source is placed in the focal centre of the soft box, the light output is approximately two times the light output in comparison to a soft box mounted on the front of a Fresnel light. A hot spot is normally encountered when using a soft box on a Fresnel light. The light distribution of the DLH400S with all the mentioned soft boxes is perfectly even and homogenous. The DEB200DU; utilising the latest technology, electronic flicker free ballasts are designed to power the Dedolight 200D and the 200S daylight / tungsten light heads. Light weight yet rugged, small yet powerful with every conceivable feature you would want. Four different versions allow powering the light from mains or from battery. • Dimmable from 200 W to 100 W • Over-voltage, overload, overheat and short circuit protection. The kit is rainproof according to IP 23 when in horizontal position.
