    The Nikon SB800 has a wide angle adapter for.... wide angle. A diffuser is
    also in the pack to make light softer.
    BUT: what IF you want a strong, small beam for a larger distance?
    Iow: use the flash as a flashlight or torch to light only small part of a
    subject from a distance.
    Is there something like that or can you make it yourself?

    It zooms to 105mm. You could manually zoom it to that setting with a
    wider angle lens and light up only the middle part of the frame. If
    you need something more than that I suppose you could make some kind
    of lens or long parabolic reflector for it.

    I've seen those, but they're to clunky, big and the beam is to wide. I'm
    looking to make a small spotlight of 2-5 inch diameter.

    Try googling "snoot" for something home made.

    Sounds like what you want is something like one of those large
    portable spotlights you can buy at places like home depot, walmart,
    west marine, etc. Take out the bulb and put in a flash tube at the
    flocal point. Maybe even another reflector in front of the tube to
    reflect the forward part of the flash back into the reflector.

    Looks like a "snoot" just blocks the light going to the side. It's
    not making the central beam any more powerful for longer range. For
    that, you need to reflect the light, like the parabolic reflector of a
    flashlight.

    I have one of these and it works: Better Beamer.

    Go knock yourself out and let us know what you came up with, as you'll
    invariably end up with something that's even bigger and more clunky,
    particularly if your goal is something with a really small spot at a
    fairly long distance. You'll be needing an optics catalog and some
    work:

    "Focus" will not accept your Better Beamer. He will make up any excuse
    in order to justify his impossible requirements. If he considers the
    Better Beamer "too clunky" and he also wants the feature of a small
    circular spot. In short he is wasting everyone's time.
