Yongnuo YN808 Bi-Color Overview The 21.7" YN808 Bi-Color LED Video Ring Light from Yongnuo is a distinctive-shaped source with a signature quality of light. While the light can be used off-axis for a lighting ratio on your subject, it's when you shoot through that you get a silky smooth near-shadowless effect that is especially kind to the complexion. A bonus is the unique circular catchlights reflected in the eyes of your subject. Instead of using daylight or tungsten LEDs, the YN808 uses both. With color temperature variable from 3200 to 5500K, you can match other fixtures or ambient light conditions or just use the custom color creatively. The YN808 can run on AC via an optional adapter, but it can also be powered by two separately-purchased NP-F750 lithium-ion batteries in locations where mains power is unavailable. Double LED Digital Display The front and back of the product are equipped with an LED digital display, which is more convenient to view power output and adjust brightness. Thanks to its double USB output, the light can charge two mobile phones or smart devices at the same time. Touch Button Function The YN808 is equipped with brightness control, whitening mode, and creative fill light mode. Four-In-One Fixed Seat Equipped with three standby hot shoe holders, provides convenient attachment of the devices such as mobile phones and microphones. Multi-Point Light Source Design The fixture is composed of 800 large LEDs with high display indexes. The light source features low energy consumption and high brightness presenting a shadowless effect. Yongnuo LED Wireless Control System The YN808 is equipped with a built-in receiver, which can adjust the required color temperature and brightness with separate purchase of a wireless transmitter. Two Power Supply Modes The YN808 runs on AC power via an optional adapter but it will also run on two separately-purchased NP-F750 batteries when AC power is unavailable.
