    If this pans out it'll be a hellova lot better than 445. Just saw that on the interesting ebay finds thread too. Nice find. Does anybody have one yet? They must have just suddenly popped up on the market? 1.4W of 462? $197?? Dammmm ..

    Yeah, I saw them on the ebay thread too, thought it deserved a re-post. It sure will be interesting to see what these things can do:-)

    Interesting! I wonder if this is worth it I love 473nm so this would be excellent.

    Myself and another member over on LPF with a spectrometer have samples coming to do testing on. 462nm should be an interesting bump from the 445nm diodes we are seeing now. Wish they were the 472nm 1.2W diodes but this will be interesting as well. Here is the datasheet.

    462nm should be just about "right" for blue IMO. 457 DPSS has got to be the best match for blue I have seen. 462... I think we'll be in the ballpark!
    If you're the smartest person in the room, then you're in the wrong room.

    This might need a new thread rather than posting under the "0.9W 475" titled thread ..
    Looking at some quick numbers 462nm should appear ~2.5X brighter than 445.

    Ah-HAH! I knew 445 was purple-ish. And some people were insisting that it was "royal blue"

    Ok, if nobody is going to start a new thread for this new diode I will ..

    Different people see these wavelengths differently. It is all in the eye of the beholder. To me it is deep blue but to some it is more violet.

    Got samples coming in already DTR? Nice!
