ring LED recommendation
Posted: Thu Sep 24, 2015 11:53 pm
While optimizing my camera setup I ordered about six different LED ring lights (usually sold for people to put around their car headlights, for "bling").
Pretty much all of them were the same, except these, which absolutely knocked my socks off:

YOW they are crazy bright! And they have a built-in diffuser too made of some sort of gelatin-like material. The wires take ordinary GND/+12V, although there's an inline inverter that seems to be a buck/boost of some sort, producing a stable+constant +9.08V across the LED terminals.
I previously built this big hideous contraption out of several layers of clear plastic, the diffuser sheets, and three different LED rings. As soon as I got the COB rings I threw that in the trash and just used them instead, with much better results. In particular, the downcam image in my other thread is illuminated directly using one of these and the other two head-mounted cameras just use the incidental illumination it produces! The ring is large enough (80mm) that you don't need a diffuser when the camera is less than 40mm from the subject.
