    For the record, I am still interested in two of the 6385's

    If the beam on the 638/632 or whatever diodes doing 170mw is as good as the beam on the 642nm diodes I'd like 2 to start and maybe 4 depending if I can live with the color.

    Thinking to blend 2 642's with 2 of these shorter wavelenght diodes. That should help me out quite a bit to balance off my 1 watt blue and 500mw green. Bet I'd need double even that to actuall match the other lasers.

    I just checked the spec sheet and the 638nm and 642nm beams are identical per the sheets. Seems a no brainer to go with the new 638nm diodes regardless of the cost.

    Thats what i thought. 637 is brighter to the eye and from what i understand you can get 200mw out of these. When my red module is finished i can swap the circuitboards with the open cans for 637nm ones. Would be a great mix 4 diodes 637 and 4 diodes 650nm

    Count one HL6385DG for me. Thanks.

    How do you guys think I would go with 2xLOC 660's and 2xHL6385DG in my quad?

    I am measuring just under 1W from the 4x660's and I need more power to balance out my green/blue.

    Do it! it would boost the red up a lot.. I think the pair of 6385's would be more visible than the whole quad LOC.
    If you have a spare colour channel you can also make use of the lower wavelength and find new corners of the palette as well

    Yes, one 640nm equals 2x 660nm

    Agreed - we have a pair of 1w's with 300mw of 642 in them and they are that much more punchy than the 660nm lasers we have.

    Hmmmmm. I do have a spare colour channel... I realigned the quad today, I got the stacking a lot tighter thanks to Andy's help. Now at 900mW (lost 60mW). It looks great, but when I fire up the CNI green it looks very dim!

    Dave, put me down for 2 x 6385's please.

    Got any pics Dave? Beam shots too would be nice.
