All other considerations being equal, the light whose reflector has the greatest orange peel will have the most additional reflected light contributed to the direct (non reflected) light coming from the LED and comprising the spill portion.
Spill is both the light you would get from the LED sans reflector as well as that additional light sent far enough out of collumn that it lands in the spill region. IMHO, the most effective flood lights are those that choke down on the lambertian distribution from the LED and take light that is well off axis and spread it within the light coming directly from the LED. A light with a tight and intense beam used at close range will provide a high level of contrast in intensities and the spill can be overwhelmed by the intensity of the beam. A spill portion of the beam may appear to be dimmer than it is due to the presence of the spot. Conversely, the spill may appear brighter than it really is in the presence of a larger and less intense spot beam.
To answer your question, I think the PM6 can be very effective for close range flood work provided you can keep the spot beam out of the target area. Use a portion of the spill or use the beam bounced with indirect lighting of the target area.
It is relatively easy to get flood out of a collimated beam but not the case when trying to concentrate the light from a flood source. A simple lamp shade or diffusing reflector can be quickly placed in front of a concentrated light like the PM6 beam. Take a white business card and hold it with your thumb extended over the bezel of a light and the card at about 45 degrees to the axis. With the card horizontal, look at your flood beam on the ground below you. This works outside or in areas where you can't bounce the light off the ceiling or walls. With a piece of tape and a white piece of paper, you can quickly fashion a difussing lamp shade for your light. Bounce those photons around some! Go for a bank shot! /ubbthreads/images/graemlins/grinser2.gif A true photon knight can get a good flood of light from any light source. For a "warm" flood, hold the bezel in the circle of your thumb and forefinger with the beam hitting the palm of your hand and then reflecting down into the target area.
