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


Conclusion

By following these guidelines and using the provided formula, you can accurately calculate the number of lights needed to ensure adequate illumination in your commercial space. If you need any further recommendations, Brite is a trusted partner in providing LED lighting solutions for your residential and commercial spaces.
