Both used QM's with dedicated colour channels and being experienced guys would've set the palettes up, probably hundreds of times in one case, he's quite insane when it comes to colours, and alignment

    That said you can't beat multi-line laser and a Machida grating for ooooooh effect IMHO
    I am using a qm and have 400mW of 473 with 1.2w of 445 and let me tell you, it does make a pretty big difference... maybe if you have 1w of 445 and 50mW of 473 it wouldn't matter, but if you have a lot of 473 it makes some amazing colors

    additionally all the people complaining about the beam specs of 445, the 445 beam, even if uncorrected, is still going to be worlds better than the 650nm flashlights the OP is talking about

    I was also thinking about that too. I am also using a QM and I remember seeing the ILDA cable specs for alternate colors. I was thinking of trying this. For beam combination though, what would be the best choice for combining the 2 blues? Even if I lose a lot of 445, it won't matter, I have 1W+ available.
    If you're the smartest person in the room, then you're in the wrong room.

ID:	25379That depends on the diodes from which factory, CNI532nm is very bright, 500mw CNI532nm real output can reach 600-700mw.

    R650nm is dark and the divergency is big, R635 is brighter than R650nm and R640nm.

    I can send you the picture showing the visiblefunction and light wavelength if you wanna.

    I think many people would do well to get a firm background in how the human eye registers color. I know that before I researched the topic I had a lot of misconceptions about it.

    Once one understands how the eye-brain mechanism works it's much easier to make decisions about color mixing.

    And BTW, the color of a 445nm laser can be simulated (almost) perfectly by mixing a 473nm with a 660nm. It is not possible to simulate 473nm by mixing anything with 445nm.

    The reason being 445nm tickles the red receptor in the eye, and there's no way to remove that red influence.
