How many fluorescent lamps should be placed below the steps of an escalator?

The correct answer regarding the placement of fluorescent lamps below the steps of an escalator is that two lamps should be installed, positioned 16 inches apart. This specification is based on industry standards that aim to ensure adequate illumination for safety and visibility in the escalator area. Proper lighting is crucial for preventing accidents and providing clear visibility for users as they approach and step onto the escalator.

Having two lamps allows for an even distribution of light, which minimizes shadows and enhances safety by making the steps and the escalator entrance more visible. The specified distance of 16 inches is optimal for achieving this balance between visibility and warmth without causing glare or discomfort to users.
