Ohhhh, a machine light. Video shot, caught my eye, thinking it was a 'desk lamp" of machine parts.
I've tried ring lights with disappointing result. maybe they've improved. The problem, parallel illumination "focuses" on area directly below, with little divergence. The large chuck shadows the drill point, unless a long bit.
Angling two Tensor-type individual lamps [incandescent or LED] at either side is more effective. The best arrangement seems to be one from the back, and left side, lessening interference to operator.
