yes. Mine had a dark pin hole (not donut hole) right in the middle of the beam which was noticable at any distance. Frankly, the LD20 was one of the worst lights I've ever owned. I don't know what makes everyone gravitate to this light. The tint is horrible, the beam is horrible, it loses low mode on Alkaline cells, only high mode works on Energizer ultimate AA cells, it lacks a forward clicky, it has a funny shape that makes it not very comfortable to hold (compared to other lights), and the output is nothing to write home about.
