When planning your lighting installation, it's always challenging to determine how many lighting fixtures to ensure adequate illumination. The Singapore's Safety and Health Standards (SS 531) - Code of practice for lighting of work places provides a guideline on recommended lighting levels for various indoor activities.
SS 531 Recommendations:
Filing, Copying: 300 lux
Writing, Reading, Data Processing: 500 lux
Technical Drawings: 750 lux
CAD Workstations: 500 lux
Conference and Meeting Rooms: 500 lux
Reception Desk: 300 lux
Archive Room: 200 lux
Basic Calculation for Lighting Fixture Levels
Once you've determined the recommended illuminance level for your space, you can calculate the number of fixtures needed using the following formula:
Number of Fixtures = (Recommended Lux Level x m2) / lumens per light fixture |
Example: Archive Room Square Metres (m2): 20 m2
Recommended Lux Level: 200 lux
Lumens per light fixture: 1000lm Number of Fixtures = (200 x 20)/1000 = 4
