A:

These are WS2812B 5050 RGB LEDs, sum 61pcs, on 5 rings. Sizes of the rings I have received: 24pcs LED: outer diameter is 86mm, inner diameter is 72mm. 16pcs LED: outer diameter is 68mm, inner diameter is 54mm. 12pcs LED: outer diameter is 50mm, inner diameter is 35mm. 8pcs LED: outer diameter is 32mm, inner diameter is 18mm. 1pcs LED: outer diameter is 14mm. Works well.
