I have been playing around w these lp's since I lost my wife 6 years ago to diabetes. This certainly doesn't make me any kind of expert. Only an expert at burning out a few diodes to static or the wrong drivers. But a lot of the blogs on meters on here are several years old. Your advice on a good watt meter reasonably priced would help me, and I am sure other newcomers on here. I posted a blog for this earlier this morning.How are you telling this, do you have a laser power meter?
It's practically impossible to tell the strength of a laser visually, even side by side there's way more to it (beam diameter, air quality, wavelength etc). If you're burning things to test the power - there's also far too many things that will change your perception of the optical power.
