The Yongnuo YN508SW Daylight 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 clamp, 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 brightness remotely via Yongnuo's free smartphone app or by an optional wireless remote control. The YN508SW is ready for worldwide use. It can run on 2 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. Two fully-charged NP-F750 batteries will give you approximately 150 minutes of run time.
