HDB lighting design: Calculating optimal brightness levels – metrics

Common metrics include lux (illuminance), lumens (luminous flux), and correlated color temperature (CCT), which help determine the appropriate brightness and color of light for different areas in your HDB flat.

Consider the rooms function. Living rooms and bedrooms usually need softer, ambient lighting (around 150-300 lux), while kitchens and study areas require brighter, task-oriented lighting (300-500 lux) to facilitate activities.

Factors include ceiling height, room size, desired aesthetic (modern, minimalist, etc.), energy efficiency (LED vs. traditional bulbs), and the specific activities planned for each space.
