    RGB White Laser Module with TTL

    OK, thanks Paul, They are not out that much. As you say it is probably the different size dot diameter. I will leave it as is. John

    RGB White Laser Module with TTL

    I have just received the Laserland RGB 300 mW Module. It appears that the colors are not aligned correctly as it is not a white light when all colors are on and it appears one color is off to the side. Is there a special technique to aligning these lasers? John
