    Sorry for the confusion, the new A140 and from what I can tell all of the A150's have the modified diode spacing.

    If that is true that could account for the change in luminosity.

    Someone needs to test this with a wavelength meter as they could be using the 460nm diodes.

    Which would be even more interesting for us as laserists.

    460nm would be the best of both worlds in blue (between 445nm and 473nm) just as 642nm is the best of both worlds in red.

    If the wavelength is slightly longer, i.e. nearing the 460nm range; I'd be happy to do another GB on the 150V's.

    If it happens to be 460nm, count me in as well.

    Imagine the brightness from a beast like that at 1 Watt. 460nm is the peak of circadian vision...

    I'll make another thread later on. It will only run if someone can confirm the wavelength with a spectrometer, or the diodes are exceptionally high slope efficiency...

    Could we work together to establish this?

    Thinking back a bit...

    I know a couple guys with spectrometers, daguin, vidal wolf, eidetic.. hmmm.

    I am set up to measure the wavelength of arrays, if someone is willing to part with an A150 array I would be happy to test it and compare to the A140 arrays I have tested.

    I can say right now though that even a whole array of 24 diodes will not say a whole lot, I have found arrays out of A140 projectors that have 435 and 460nm diodes in them-the wavelength spread is very wide.

    I have an A150 diode I will gladly send to anybody who has the capability and time to thoroughly test it.
