Camera LED Ring light

This is a 24 LED ring light for film/photography that I needed for a single shot where my squared light didn't the deliver the look.

It is powered by 4 AA batteries, the LEDs are 3mm low power (2mA) LEDs attached with a drop of hot glue on the back of the ring.
All 24 LEDs are put in parallel but you could arrange them in any way you want.

It has a 1/4 inch hole that you can screw on to a ball head - PLA is soft so there's no need to tap thread just twist it on the 1/4 ball head.
