2 years 2 months roughly to go until 100,000 hours.

It's been nearly 10 years, what am I going to do, stop now?! I said that after the first year, then 3 years, then when it outlived styro's. I'm kind of committed to it now lol.Wow. 80,500+ hours! That’s seriously impressive. Both in the sense of the diode longevity and that fact you are also still recording it.
So March of 2025 ish? Maybe that will be the next update lol2 years 2 months roughly to go until 100,000 hours.

Actually it is the current you are running it at in mA. The voltage, or Vf is not meaningful.I'm running it at the 5V rating.
I guess I should clarify. These don't have driver circuits. Because they are so cheap, they only have a 92Ω resistor. The Vf of the diode is 1.834V and I'm running it from a 5V constant voltage source.Actually it is the current you are running it at in mA. The voltage, or Vf is not meaningful.

When I said the rated 5V, that's because that is how they advertised it. I don't have any real way to test the current draw without disconnecting the diode.
You can still figure out the current coming through the diode if you know the Vf of the diode. Subtract that from the 5 volts to get the voltage drop across your resistor and use Ohm's law to get the current.
I just did it for you. I=0.034 amps or 3hat is the measured Vf of the "other" diode of the same type, I'm not well versed in

I'm admittedly not well versed in the voltage characteristics of laser diodes, ohms law I've got down, but I thought they didn't obey ohms law as they aren't linear.
Do you think it could have LED'd?It was so little power to begin with that it's hard to really tell. In a daylight lit room, on a wall 15 feet away the dot is still easy to see.
My power meter didn't even register this thing years ago when I tried. Since quantifiable data aren't available, and given the 10 years that it's been, I would say it seems more dim,
Real time edit. I just checked it side by side with the last unused diode from this batch. Power output has reduced significantly.
