New evaluation: S3 Krypton Green DPSS Portable Laser (300mW vers.)

[yobresal]

He may have meant that the new one has several modes that the original did not have and by additional he could have very well meant additional besides off and on. That is how I read it but that might be because I know about which models have what modes.

Disregard the average readings from those meters. They means nothing. It calculates into the average the 20 seconds or so of readings that the meter is showing while it is still climbing to what the laser is actually putting out.

Thanks, but that brings me to a few more questions about the Graphs (not the laser). In his first graph for low power, the numbers shown sort of look OK and match the power graph line, However in low mode the Krypton is only putting out 10% of power; so after reviewing that graph again it would appear that is not correct either. It's stated to be 371mW for full power (peak/max?) so it should show low power around 37mW.

The graph for the high power is even worse with the numbers displayed vs what the power line shows, can you explain a little more about the 20secs thing?

This is why I prefer professional equipment WYSIWG, but I do understand the need for a cheaper hobby solution.

Update:
I clicked on the link in this thread for the review on the Arctic, and I see the Graphs in that review look just fine (power line & average numbers displayed at the top) yet the ones here don't match-up too good, I wonder why? Wouldn't the 20sec thing that is talked about apply here too?

Your power measurements you did for your reviews don't seem to be like these ones though :thinking: and seem correct, yes/no?

What you're probably seeing (the "average" power indicator being significantly lower) is probably due to how I conducted the tests...first I took the reading at "low" power, performed a screen dump (yes, that's really what its called!), then 150 or so seconds into the test, switched the Krypton to "high" power and allowed the same test to continue for another ~100 seconds before dumping that screen and then shutting the LPM down.

Once the Krypton is finished with the battery discharge analyses of "beacon" mode that I was asked to perform (it's been nearly 24 hours and it's still plugging along!), I'll pop a new battery in and re-take that high power test, k?

Sounds good, just trying to understand what is being presented in the Graphs. Good luck on waiting for the Beacon mode to deplete the battery.......that may take some time :beer:

I just took another power measurement of the Krypton in "high" mode...this time, it registered at 412mW!!!

I simply suspended the "Beacon" mode test in progress, changed out the battery, measured, changed the battery back, and resumed the runtime analysis.

Great review! I have been hovering on this site for a long time, thanks for the pictures and stats :gj:

The Krypton is a fine Laser for sure.

Sorry but I think Steve Liu is pulling the wool over your eyes
about that Laser being a 300mW version...
I still think he sent you a 500mW version now seeing the old
and new graphs since he claims 250mW - 500mW for it.

I can't possibly see WL sending out an OVERSPEC Krypton...

This is why I prefer professional equipment WYSIWG, but I do understand the need for a cheaper hobby solution.

Everyone would prefer to have Professional Equipment but we are
all not as fortunate or as rich as you to be able to afford a $4,000.00
LPM that you so proudly show in your Sig...
