Ring lights have LED bulbs. A larger ring holds more LEDs, which increases the output of the light. A larger diameter also distributes light across a wider space, this goes to say the bigger or wider the ring light the brighter the light. With a small ring light, the LEDs are close together. Causing the ray of light to be concentrated, making the LED less likely to illuminate an object which is far from the camera. However, the concentrated light provides greater illumination for a close-up subject. However, it is important to note that size is not the only factor to consider when choosing a ring light. Two 8-inch ring lights from different companies may produce two completely different results.
