Low Ambient with Task Lighting,
including occupant control of ambient
lights
 Study looked at preferred cubicle lighting levels using a
dimmable overhead lighting, under cabinet lighting and
portable LED task lighting
 Hypothesis is that when occupants have control of the
overhead lighting levels and have access to efficient task
lighting, overall lighting levels will be reduced
 Key findings
– Overall lighting levels reduced by 5 to 19%
– Distribution of light is critical to satisfaction levels
 Further work required to focus on task lighting criteria that will
allow for lower ambient lighting levels and increased
satisfaction levels
