Client requirement:The illumination brightness of the chain supermarket needed to be increased by 10% and the illumination needed to be uniform without any dark zones. The average illumination should be 300lux. The evenness should be more than 0.5 and the energy saving rate should be above 50%.
Solution:According to the customer’s requirements and the actual situation, we suggested replacing the 28x3=84W fluorescent lamp with the 30W LED panel light with a high luminous efficacy. The project needed a total of 6800 sets of LED panel lights.
Results:The energy saving rate achieved more than 65%. The illuminance was 350lux and the evenness was 0.6. Our client’s return on investment was compressed from 3 years to 1.3 years.
