Bought 100 pieces of LEDs. 50 degrees. All LEDs have a hole in the beam, I'm not sure if this is normal, maybe it's some kind of defective batch. When I insert them into a Streamlight with 7 5 mm diodes, it does not matter, it turns out a beautiful flood beam. I'm wondering, if somehow grind the lens part of the LED, is it possible to get rid of this hole? I want to insert these diodes into 1 diode flashlights that go for gifts. Although those to whom I give them do not pay attention to the presence of holes at all and even to the color of the diode (if it were pure blue they would not have noticed), but my OCD does not give me peace.
