Combined with a built-in USB charging port, this makes it one of the most portable ring lights on the market. The max-height 7 ft tripod can be adjusted to accommodate sitting or standing, while the smartphone clamp, swivel ball, and Bluetooth remote make the device fully compatible with your iOS or Android device.
