Which of these statements is FALSE with respect to lighting stairways?

The statement regarding MR16 downlights with NSP (Narrow Spot) lamps is considered false in the context of lighting stairways. Staircases often require lighting that provides uniform illumination to promote safety and visibility as individuals navigate the steps. While MR16 downlights can indeed be effective in certain applications, the use of narrow spot lamps may create concentrated beams of light that result in uneven lighting patterns. This can lead to areas of shadow or excessive brightness, increasing the risk of accidents as users move up and down the stairs.

In contrast, broader beam angles or diffused lighting sources tend to be more effective for stairway illumination, as they help minimize glare and improve overall visibility. The other statements highlight best practices for stair lighting, emphasizing the importance of control placements for accessibility, the critical nature of illuminating landings, and the potential glare issues from certain fixtures, all of which support effective and safe stairway navigation.
