?Frequently Asked Questions
Do LED lights really have a 50,000-hour lifespan?
A 50,000-hour lifespan is the theoretical value from laboratory testing. Actual lifespan in varied working environments is typically around 30,000 hours, though it can reach 50,000 hours if high-quality materials are used.
Why do different suppliers have different brightness for the same power?
Brightness depends on the LED chips used or different brightness versions of the same chip. While the same chip version will have minimal differences, the overall fixture design also impacts the final lumen output.
What is Color Temperature (CCT)?
Kelvin (K) measures the "temperature" or color of the light. Lower color temperatures (warm) are used in public areas for relaxation, while higher color temperatures (cool) enhance concentration in industrial and office settings.
What does CRI stand for?
CRI (Color Rendering Index) is a figure that indicates how accurately a light source reveals the true colors of objects. A higher CRI typically results in higher quality light and costs.
What are PF and efficiency in LED drivers?
PF (Power Factor) and efficiency reflect the electrical performance of the driver. Higher PF and efficiency indicate better energy conversion and higher-quality electrical components.
Where can these UFO LED high bay lights be applied?
These lights are ideal for industrial and large-scale commercial applications including mines, gymnasiums, shipyards, exhibition halls, warehouses, shopping malls, factories, and tunnels.
