The Nanlite 600-CSA Bi-colour LED Panel with V-Mount has four barn doors for protection of the panel and control of spill, this 600 panel will adjust from 3200 Kelvin to 5600 Kelvin. Useable in both the studio or on location, this unit produces over 3300 Lumens of variable colour output, daylight to tungsten balanced light. The Nanlite 600CSA can be powered by mains power (110-240V) or utilise the V-Mount battery buckle built into the rear of the panel for location shooting. The included modifiers (standard diffuser, super soft diffuser) are used to adjust output to suit many standard lighting situations. At just 1.9kg, this light is a great panel for mobile T.V. camera operators as well as event videographers or corporate video shooters. The mounting bracket features large, easily adjusted fasteners and is angled slightly forward of centre to offset the weight of a V-Lock battery if used. Seamlessly adjust the light from 0-100% and never worry about flickering thanks to Nanlite's high quality diodes and boards.
