Highly versatile in terms of color flexibility and power options, the NC660B Bi-Color LED Monolight from Geekoto suits studio, film, and TV productions. The NC660B stands out by offering a convenient 2700-6500K bi-color punch, 0-100% dimming, 16 film scene modes, and a noiseless cooling system. The light runs on AC power for indoor setups, but it will also run on a separately available V-mount battery for on location work.
