The color-rendering index (CRI) is a quantitative measure of the ability of a light source to reproduce the colors of various objects faithfully in comparison with an ideal or natural light source. The stunning revolution in HR672C with CRI95+ ensures that its light is natural and lifelike. It is perfect for color-critical applications such as fashion, documentary and short films. HR 672C is the most advanced Amaran light built to date. It emits 4636.8 lumens of light, about equal to traditional 400W incandescent light. Also, no matter the shutter speed or FPS, it never flickers. The HR672C is only 32mm in thickness and about the same size as an iPad. It s lightweight and compact, but includes 672 LED beads.At 33 percent thinner than common LED video lights, its geometric shape makes these lights easy to carry in groups. The portability and power allows you to create and set the atmosphere in any environment. Using 2.4G FSK technologies, the HR672C can be adjusted in brightness and color temperature wirelessly using a remote. The multiple channels and groups also ensure that several different lights can be controlled without interference or confusion. Control with precision, even 100m away. Designed for maximum heat dissipation, the HR672C uses ventilation holes and unique technology to cool itself. Instead of using a cooling fan, we utilize natural heat dissipation, which is energy-saving and safe. Most importantly, the HR672C is completely silent in operation.
