The illuminance standards for commercial lighting vary depending on different commercial spaces and purposes. For example:
The lighting requirements for supermarkets vary in different areas. The illumination requirements for the entrance area are usually between 150-300 lux (Lux), for the shelf area between 500-1000 lux, for the cashier area between 300-500 lux, and for the aisle area between 150-300 lux. ‌1
The average illuminance of general lighting in department stores is 500 lux for high-end department stores and 300 lux for general department stores. ‌2
The lighting standards for shopping malls are more detailed, including general lighting, key lighting, and decorative lighting. The illuminance for general lighting is between 100-200 lux, for key lighting it is between 500-800 lux, and for decorative lighting it is between 800-1500 lux. ‌3
These standards aim to ensure that the lighting in commercial spaces meets both visual needs and enhances the shopping experience and product display for customers.
