The Halo 16C Bi-Color Tunable RGBWW 16" LED Ring Light from NanLite features has a distinctive form factor and a color temperature that's variable from 2700 to 6500K to match other fixtures, ambient light conditions, or just for creative expression. It's also dimmable from 0 to 100%. These adjustments can be made by a clever touchpad, accessible from the front and rear. The Halo 16C also has another trick up its sleeve: RGBWW that gives the user a choice of 360 colors to add a personal touch to your work. Ideal for selfies, the ring light has a central opening of 12" allowing you to use the provided smartphone bracket to shoot through it for a smooth near-shadowless effect that is flattering to your talent's (or your) complexion. Another bonus is the unique circular catchlights that are reflected in your subject's eyes. The Halo 16C runs on AC power via its included adapter, and it also has a USB port to keep smartphones and other devices charged during live streams, extended video shoots, time-lapses and more. A carry case is included.
