Drill a slightly smaller than LED-sized hole, and insert LED, us a little hot glue if needed.

Suffused glow, no hot-spots. Very pretty.

It must be the wrong season for ping-pong in England right now. Anyway, they work as LED diffusers, but the LEDs aren’t very bright.

I sanded the LEDs (two per ball) before inserting which helped diffuse the light.

Ping-pong balls are made of cellulose, which is not very stable, especially in exposed/outdoor environments. See this link for some details.
