Light Distribution on Task Plane (Uniformity): Design luminaire layout to
uniformly distribute light over the work-plane to avoid dark areas in the
Shadows: Select and locate luminaires to avoid shadows on the repair
areas of the hangar. Portable task lighting can also increase the
illuminance on the task as well eliminate shadows.
Target Horizontal Illuminance ( 10%): 500 lux (50 fc)
By introducing daylight high in the space, much of electric lighting can be turned off
during the day. Although light level is important to achieve in a hangar, uniformity and
the prevention of glare and shadowing also must be achieved to provide a comfortable
and functional workspace. Portable task lighting allows for higher light levels at the task
location without increasing the overall ambient level.
