Most people seem to want as narrow a beam as possible for burning etc, but what about making a wide beam? I would like to be able to adjust the beam from narrow to wide, eg something like 10cm @ 1m. I am thinking about getting a Sony diode preinstalled in an Aixiz module from Stonetek. Do these modules give you a wide range of adjustment? Is it easy to adjust using only your fingers? Thanks.
