We use Manfrotto gear throughout our studio, so I was very excited to get several boxes of new light panels, the 1x1F model. The lights are very lightweight, which will make them great for travel. The panels emit light with a beam angle of 50°, with a brightness of 1400lux at 5600K. Intensity can be varied from 0-100% with no color shift or flickering. They're GREAT lights and we can't wait to put them to use in our studio.
