    True.
    I recently setup 30 PL450B's and while I didn't have time to run them into the spectrometer, I ran them all side by side and two of them were *clearly* a longer wavelength. It was as clear as putting a 473nm next to a 457nm.
    These diodes were all from the same tray out of the factory.

    ah, you found two useless "aquamarine" diodes
    this should make some awfull yellow

    No worries I'll take them off your hands

    I would really like to get a 470, but it's like the luck of the draw. My luck, I'd just get another 445-450

    Seems to me that NDB7675 is the result of sorting from our chinese friends, as for example NDB7775 in fact is NDB7875 but with "lower power" imperfection. And in the future we will see are many more NDB7XX5 different diodes

    Received my sample today. It is a much nicer blue. No need to measure the wavelength to see the difference between 445nm and 462nm. My sample lases at 461.5nm @ 1400mA putting out 1.482W

    Yep seems to match up with what RHD got with his.
    0.3A - 456 nm
    1.0A - 459 nm
    1.5A - 461 nm
    1.7A - 462 nm
    1.9A - 463 nm
    2.0A - 464 nm
    2.1A - 465 nm

    My sample starts to lase at 457nm and goes up to 461nm. So it is far away from 445nm and I think is worth the money when when real blue matters.

    Well this is great news!! I'll be putting in my order next payday (about 2 weeks away) Can U hold one for me Jordan? I'll be getting one in the copper module . What collimating lens are you guys using for these?

    I did my tests using this one http://www.photonlexicon.com/forums/...een-Red-Lasers
