Task lighting is not intended to light an entire room
Bedside task light can be wall or table lamps. Measure height of the seated user’s eye level, and place opaque shades just above shoulder, or place the center of a translucent shade at their eye level.
A single center-mounted ceiling light is often not a good task light. In this case, the user’s body blocks the light from shining on the task area.
Track lighting and down-lights also need to be placed where they will shine on the task and not on those performing the task.
Under-cabinet lighting mounted at the front of the cabinet bounces light off the backsplash and onto the countertop—the task area
Lighting a counter and backsplash made from glossy material takes extra care--to avoid glare and veiling reflections: mount adjustable recessed luminaires to give cross-illumination
Another example of a single source of light giving harsh shadows and no “fill” light
Linear task lights mounted near the back of the upper cabinet create a distracting glare for a seated diner—mount at front and use a fascia strip
