Brightness settings are also important. A ring light that can adjust between 0 and 100% brightness offers you the most control, but lights with low, medium, and high settings are often enough to get the job done.

The slider ranges from "1" or the dimmest setting to "10" for the brightest setting. For best battery life, select the lowest brightness that works for you.

Brightness is pre-set to 50% to start, but you can go down to 10% or up to 100% (500 lumens).

With some ring lights, you can adjust the brightness from 0 to 100% in 10% increments (10% brightness, 20% brightness, and so on), but we prefer models that let you fine-tune the brightness to the nth degree.
