    Wohooo finally managed to get some "decent" alignment by tweaking the mounts and a bit of luck, definitely not perfect but acceptable to me, for now...
    the reds remains "aligned" whether the projector is 3m or 12m from wall so it guess we're pretty good regarding parallelism of the beams. We're getting there thanks guys!!

    Good you had some success.
    Yes, with knife edging you have to make some sacrifices usually.
    The trick is to get the beam from the left red in your module pic as close to the tip of the prism as possible, and have a little bit of waste beam down the back of the prism.
    Then get the right hand beam as close to the tip of the left prism as possible where it comes across - again a little bit of waste beam is going to hit the back of the prism.
    So you sacrifice a bit of lost power (although its not where the most power is), for a beam that is more coherent and singular, and probably a bit more power density as a result.
    I think that GS play it a bit too safe in terms of the clipping, which leads to nice high power figures, but with that big gap in the middle.
    I may just put a PBS and waveplate in mine.

    You are using Bonetti's defense against me, ah?

    I thought it fitting, considering the rocky terrain.

    Hi bricenc,

    How have you been getting on with the 3w and 4w lasers since your last post?

    I have been considering both these and if you have a moment I would really be interested in finding out more about what you think of them.


    1. Now that the beam alignment has been fixed, in terms of colors and intensity how does the 3w compare to the 4w?
    2. You mentioned that you felt the scanners on the 3w where performing better than the 4w, is this still the case?
    3. On the 3w, do you find that the blue overpowers the Red and Green?
    4. On the 3w, do the beams mix well and medium distances, say 7.5 to 20 meters?
    5. Anything else you think about them?


    Thanks again for posting your thoughts on these, it's been really helpful.

    I am also considering the more expensive projectors from 8lightspace. But these are a good bit more money and for my purposes may not make sense.

    Sol B.

    Sol, I think I may have covered this in my PM on SP (assuming you're not some other Sol...), but GS can build projectors to your spec, so you can decide which scanners you want in there.
    Personally one of the most consistent bang for buck scanners I use is the PT-A40.
    So you can pretty much get the performance you want for your budget. I think they use the AL scanners because they're the most cost effective but a little more will get you the PT's, which is what you'd get in the Lightspace units I believe.

    Hi Norty,

    Yes thank you, I am very much now leaning towards the 3w, and probably the standard scanners will be sufficient for the shows I am looking at, it seems like very good value.
    I have very much taken your advice on board and reading this thread I now understand the difference between these two units a lot better.

    Since the bricenc has both units, I was just interested in getting a bit more of his feedback on them. In particular how he feels they compare to each other.

    Many Thanks
    Sol B

    Hi Sol, comparing the 3w and 4w, the 4w is really red, the 3w a bit blue but still more white than the 4w.
    They are both the same "visibility" and the 3w has slighlty better/ smother modulation.

    Overall i would the 3w unit because the case is smaller too. i am considering selling the 4w and getting a lightspace starbust 3w

    i recently got my hand on an Akai APC40 mk2, before realizing it doesnt work natively with quickshow as the mk1 does... do you guys have any tips to make it work?

    here's a video of the last party we did with the two lasers. (3w on the left)
