The Yongnuo YN508SC Bi-Color LED Ring Light is literally two lights in one. The breakaway design lets you use both halves of the ring light to provide two lighting angles. Or, you can use them together for the classic, near-shadowless, halo-in-the-eyes portrait look. With the integrated smartphone holder, such portraits can be achieved with your mobile device, and a U-type yoke is included to make that easy. Besides making adjustments on the fixture, you can also control color temperature from 3200 to 5500K as well as the brightness level remotely, via Yongnuo's free smartphone app, or by an optional wireless remote control. The YN508SC is ready for worldwide use. It can run on two separately purchased, multi-voltage power adapters and thanks to its battery plates, it can also run on optional NP-F batteries when AC power is inaccessible.
