The required High Bay light models and quantities for different sizes and purposes of spaces.
Your lighting needs depend on the size and purpose of your space. First, let's determine the purpose of your space because it dictates the required illuminance (lux) per square meter. Different purposes need different amounts of light. Illuminance (lux) is the amount of light received per square meter, measured in lux (lx). Specifically, it indicates how many lumens (units of light) hit each square meter. For example, 1 lux means 1 lumen per square meter. This concept helps describe brightness levels to ensure the light source meets the specific needs of a space.
Different spaces require varying levels of illuminance depending on their use and the activities conducted within them. Here are some common locations and their recommended illuminance levels, measured in foot-candles (FC) and lux (1 FC is approximately equal to 10.76 lux):
Residential and Office Spaces
Bedroom: 10-20 FC (100-200 lux)
Living Room: 10-20 FC (100-200 lux)
Kitchen: 30-50 FC (300-500 lux)
Study or Desk Area: 50-75 FC (500-750 lux)
Bathroom: 30-50 FC (300-500 lux)
Commercial Spaces
Office Work Area: 30-50 FC (300-500 lux)
Conference Room: 30-50 FC (300-500 lux)
Reception Area: 20-30 FC (200-300 lux)
Retail Stores: 50-100 FC (500-1000 lux)
Restaurants: 5-10 FC (50-100 lux)
Warehouse and Storage Areas: 10-30 FC (100-300 lux)
Industrial and Manufacturing
General Manufacturing Areas: 30-50 FC (300-500 lux)
Fine Work or Inspection Areas: 50-100 FC (500-1000 lux)
Assembly Line: 50-75 FC (500-750 lux)
Educational and Healthcare
Classrooms: 30-50 FC (300-500 lux)
Laboratories: 50-100 FC (500-1000 lux)
Hospital Wards: 20-30 FC (200-300 lux)
Operating Rooms: 100-200 FC (1000-2000 lux)
Outdoor
Parking Lots: 5-10 FC (50-100 lux)
Sidewalks and Walkways: 10-20 FC (100-200 lux)
Sports Fields: 30-100 FC (300-1000 lux)
These values are based on general standards and recommendations and can be adjusted according to specific requirements and regulations.
After understanding the required illuminance for different spaces, you can calculate the total illuminance needed for your space to match its purpose.
