Q: Do LED lights really have a 50,000-hour lifespan?
A: A 50,000-hour or longer lifespan is theoretical based on lab tests. Actual lifespan in varied working environments is typically around 30,000 hours, though it can reach 50,000 hours with high-quality materials.
Q: Why do different suppliers offer different brightness for the same power?
A: Brightness varies due to different chip brands or different brightness versions of the same chip. It is also important to distinguish between the brightness of individual LEDs and the total output of the lamp fixture.
Q: What is color temperature?
A: Color temperature is measured in Kelvin (K). Lower temperatures (warmer light) are often used in public areas for relaxation, while higher temperatures (cooler light) enhance concentration in office or sports environments.
Q: What is CRI?
A: CRI (Color Rendering Index) represents how accurately a light source reveals the true colors of objects. A higher CRI generally involves higher production costs but provides better visual quality.
Q: What is PF and efficiency?
A: PF (Power Factor) and efficiency indicate the electrical performance of the LED driver. Higher PF and efficiency values signify better energy utilization and higher quality components.
Q: How does the working environment affect the light?
A: The operating environment (temperature and humidity) significantly impacts the actual lifespan and performance. Our lights are designed to operate between -40ºC and +80ºC.
