Both of these burn way batter than my green But, I am not sure about the scatter I am getting. I have attached picts of the 3. I can focus the pocket mini kits to any distance but there always seem to be a lot of irregularity in the beam. The center is tight and focused but there seems to be a ring or ellipse around them. Do these look typical? It is possible I didn't press the diodes in far enough? They are flush with the mount. Oh, I am running the lass lens on the 405nm and the acrylic on the 650nm. I have already cleaned them with a q-tip and rubbing alcohol but it didn't seem to help.
Thanks
