How high should lamps and lampholders over lanes in commercial garages be located above the floor?

The correct answer indicates that lamps and lampholders in commercial garages should be installed at least 12 feet above the floor. This height is crucial for several reasons related to safety and functionality in a commercial garage environment.

First, placing lighting fixtures at this height helps to minimize the risk of damage from vehicles and equipment. In areas where heavy machinery or cars frequently operate, installing lamps too low could lead to them being struck and damaged, which would not only necessitate replacements but could also create unsafe conditions if the fixtures were to fall.

Moreover, a height of 12 feet helps ensure that the light distribution effectively illuminates the working areas without posing a head hazard to individuals walking through the lanes. It promotes better visibility, which is essential in preventing accidents in busy garages.

Additionally, such requirements align with safety standards and building codes that mandates minimum heights for fixtures to mitigate hazards while ensuring effective lighting. This consideration is particularly important in commercial settings, where both safety and efficient operation are paramount.

Overall, choosing 12 feet as the mounting height for lamps and lampholders in commercial garages strikes a proper balance between illumination, safety, and protection for the fixtures themselves.
