Higher frequency/ shorter wavelengnth=better material absorption due to greater molecular/electron excitation and less energy loss. 450ishnm is a very balanced wave true, but if higher power nearer uv get cheaper =better
Since joining this hobby 15 years ago, I have learned awe Sh*t the stupid way like many others. If you want something in particular then have a pro do it. It costs less in the long run.
I would like to pose/clearify a good question: by bridging the resisters on a set SXD V3 what output increase can I get? for example, can a 3.5A output be changed to 4.0A output ect.
