Heyo. Nobody made a thread reviewing these yet so here one is.
I have a total of 6 diodes - 4 of them are between 425-426nm @800mA
One is between 422-423nm @800mA
And lastly one is 420nm @800mA
This is in a part of the spectrum where color shift is dramatic over a couple nm, similar to 488-495nm. 420-422nm is a sweet spot for being dead center between blue and violet. My 417nm looks just like 405nm to me, and 425nm is still bluer than it is anything else. Seems like these will unfortunately be a bit of a gamble trying to get the low wl bins unless you feed them a smaller current. I found that at threshold, they run around 3nm lower than at the 800mA in the spec sheet, which is about right for GaN based diodes.
420nm being the sweet spot it is for being a distinct enough color to me, I got that into a custom host which I'll be showing for the remainder of this post. 420nm is such a nice color, I'm so happy to also have the funny number laser.
