I've had a few diodes and most of them output like this. I was wondering if it was normal. I know it's not the lens because when I twist it the line stays stationary. The beam looks fine and they burn fine, but the dot makes this strange pattern. Ignore the bright dot below the main one, it was reflection in the camera.
The diodes are SLD123VL's the old Senkat one's that were the "good batch"
They are running about 220ma.
Anyone seen this before?
