Limitations
Light shelves may not be suitable for all climates. They are generally used in mild climates and not in tropical or desert climates due to the intense solar heat gain. These hot climates, compared to mild climates, require very small window openings to reduce the amount of heat infiltration.
The fact that light shelves extend a fair distance into a room may result in interference with sprinkler systems. In Canada, they cannot exceed 1200 mm (4 ft.) in width if sprinklers are present or the design will require integration with sprinkler system to cover the floor area under the light shelf. They also require a higher than average floor-to-ceiling heights in order for them to be effective, or daylight may be inadvertently redirected into occupants' eyes.
The distance into a space that light is cast is variable depending on both the time of day and the time of year.
Light Shelves also increase maintenance requirements and window coverings must be coordinated with light shelf design.

Famous quotes containing the word limitations:
“The only rules comedy can tolerate are those of taste, and the only limitations those of libel.”
—James Thurber (1894–1961)
“Much of what contrives to create critical moments in parenting stems from a fundamental misunderstanding as to what the child is capable of at any given age. If a parent misjudges a child’s limitations as well as his own abilities, the potential exists for unreasonable expectations, frustration, disappointment and an unrealistic belief that what the child really needs is to be punished.”
—Lawrence Balter (20th century)
“The limitations of pleasure cannot be overcome by more pleasure.”
—Mason Cooley (b. 1927)
