Function: Ring lights are circular-shaped LED lights used to provide soft, even, and shadowless illumination on a subject.
Purpose: They are popular among content creators, including YouTubers, makeup artists, and social media influencers, for video recording, live streaming, makeup tutorials, portrait photography, and selfies.
Design: The camera or smartphone is typically placed in the center of the ring to ensure light is evenly distributed around the subject and to create a distinctive catchlight (halo effect) in the eyes.
Features: The one in the image appears to be a larger size, possibly 12 inches or more, and likely features adjustable brightness and color temperature settings, which are common in such products. It also comes with an extendable tripod stand for height and angle adjustment.
