Any soft source by nature has weak throw. Put a big diffusion panel in front
of a hard directional light and you'll have a softlight with fast drop off.
Kinos are great. A 4x4 (four bulbs that are each four feet long) uses 160
watts and puts out a considerable amount of light. The output of Kino bulbs is
essentially the same as any household or industrial fluorescent unit; the big
difference is an electronic ballast for no flicker and color-corrected bulbs.
Very useful and versatitle lights, but they can be large and unweidly in tight
spaces (that was a four foot long unit I was mentioning).
