I'm really glad you asked about the diode. It's been a long year, and not just for the obvious reason...

In November 2020 we experienced a 13 day power outage. The diode was placed in my travel battery bank, the same one I have been using since starting this experiment. It allows me to swap in 18650 batteries without interrupting power. It was a hectic period right when I should have been posting the annual update. This was immediately followed by the birth of our newest laser enthusiast.

So with the passing of another year (or two) that brings the current run time to 66,105 hours!

To answer your questions sowee, I have seen no obvious change in any of the properties. The dot is still easily visible even with lights on or during the day with the windows open.
i might try an experiment similar to yours. ill be using a 650nm module (like yours), a 532nm dpss module and one of my spare 545nm lasence modules. thanks so much for giving me the idea to try this out.

That is actually incredible. 7.5 years non stop operation.
