Here's a series of experiments showing different reflector layouts - best results were with the 10 degree center reflectors.
This image shows the 10 degree reflector with 3 perpendicular 3mm thick black blinds spaced evenly along the length of the fixture. The additional light shaping creates a projection with much less spill and a similar luminous intensity to the units mounted 7 inches lower.
