The Yongnuo YN508 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 halo-in-the-eyes portrait look. With the integrated smartphone clamp, such portraits can be achieved with your mobile device. Additionally, your smartphone can control the light's brightness and temperature with the free mobile app. Each side requires its own power source, with each fixture having a Sony L-series battery plate and a barrel connector for a separately available power supply. When both halves are connected, the included yoke can be used to mount the light and tilt it to get the desired look.
