The YN6000 Bi-Color LED Panel is one of a series of dimmable LED lights from Yongnuo with color that's variable from 3200-5500K to meet any ambient light challenges, match other fixtures, or to spark creativity. The light's high CRI rating of 95 is an indicator of precise color rendition. A downloadable mobile phone app is available to control the light with separate purchase of a receiver. Designed for work in the studio or the field, the YN6000 runs on a separately purchased AC adapter or two NP-F batteries, when mains power is unavailable. A softbox and a storage bag are also included.
