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.
