If I recall correct this is very near the same as OPSL blue.

Just as I plan any upgrade the parts for said upgrade always become yesterdays technology.
I got two Osram 450nm 1.4W diodes waiting to be fitted by Rob (Stanwax).

Great! Thanks Jordan
Carl- sorry to hear that .. seems tomorrow's technology is always yesterday's technology today .. 'tis the nature of the beast I suppose ..

Posting to keep track. Really looking forward to this.

^ yeh, me too
Oh, and I need to mention that the original post / finder of this new diode was not me, but a new member Crazy who posted this over on the "interesting ebay finds" thread.

this was just posted over on LPF, thought i would share it with those of you who havent seen it. Finally a brighter blue direct diode. I am assuming Nichias goal was/is to make a diode replacement for DPSS 457, but who knows. Of course, they are multimode, and divergence is nearly on par with the newer 3.5W 445's. I imagine we will see these in higher powers soon, and hopefully with less crapworthy divergence (or a multiwatt single mode- we can wish, I guess )

Welcome to PL Crazy !!

Soooo I know some one here can tell us how much visibly brighter 462 is than 445.....

[steve-o]

Wellll .. crunched a few numbers earlier and it looks like roughly 2.5X. 445=.030 and 465=.074, using a standard 555=1.000 table.
--and credit goes to you too Stiffler for the re-post on another thread which brought this new find to everyone's attention
Cheers !!

So that basically means this should appear as bright as the brightest 445 available...I wonder what the beam quality will be:-)

[steve-o]

There's some smart people on this forum. I'm sure that the beam quality will get sorted out
