Common misconceptions about lighting design
Many facility managers incorrectly assume brighter lighting improves productivity, whereas studies demonstrate that lighting quality, spectrum, and glare control prove more critical than brightness alone. Excessive brightness creates discomfort, increases eye strain, and wastes energy without performance benefits. Proper lighting design focuses on delivering appropriate illumination levels for specific tasks whilst minimising glare, shadows, and visual discomfort.
The misconception that any bright lighting suffices ignores substantial evidence showing poor lighting design reduces customer dwell time and negatively impacts purchasing behaviour in retail environments. Harsh overhead lighting creates unflattering shadows and colour distortion, diminishing product appeal and store atmosphere. Strategic lighting design considers colour rendering, beam angles, and fixture placement to create inviting environments that support business objectives.
Colour temperature selection significantly impacts space perception and occupant comfort. Cool colour temperatures above 5000K suit task-oriented environments requiring alertness whilst warmer temperatures below 3500K create relaxed, comfortable atmospheres. Mismatched colour temperatures for space functions create discomfort and reduced satisfaction regardless of brightness levels. Understanding these nuances prevents costly mistakes during lighting system specification.
Common lighting design mistakes to avoid:
- Specifying excessive light levels that waste energy and create discomfort
- Ignoring colour rendering index (CRI) when selecting fixtures for colour-critical applications
- Overlooking glare control through proper fixture selection and placement
