Q: What does the
- Color Rendering Index (CRI) refers to the ability of a light source to restore the visual perception of objects under sunlight. The higher the color rendering, the closer the CRI value is to 100, indicating a stronger ability to restore the color of objects, making it easier for the human eye to distinguish the colors of objects. CRI is a measure of color recognition of a light source compared to a standard light source (such as sunlight). CRI is a widely accepted indicator and is currently the only method for evaluating and reporting the color rendering ability of light sources. High color rendering (CRI290) luminaries emit a soft and comfortable light like morning sunlight, reducing visual fatigue and enhancing clarity of vision and three-dimensional images, providing users with a high color rendering outdoor lighting experience.【See More】

Q: What does LM90B50 mean for LED lighting fixtures
- The percentage of lumen maintenance over the initial lumen is defined, which means comparing the luminous flux of a luminaire that has been operating for a period of time with its initial luminous flux. L70 indicates a reduction in flux to 70% of the original, L80 to 80%, and L90 to 90%. The B value represents the failure data at point L. B10 indicates that 10% of the LEDs fail to meet the requirements. Therefore【See More】

What are the sterilizing, antibacterial, and purifying effects of air purification lamps?
- Air purification lamps, also known as disinfecting and sterilizing lighting fixtures, primarily function to decompose indoor polluted air and exchange it with fresh and healthy outdoor air, thereby ensuring indoor air quality and creating a healthy and comfortable living environment. They also serve as basic lighting fixtures, integrating air purification, sterilization, antibacterial capabilities, and lighting functions.【See More】
