Do LED lights really have a 50,000-hour lifespan?
A 50,000-hour or longer lifespan is typically based on laboratory tests. In real-world environments, the actual lifespan may vary but can reach 50,000 hours if high-quality materials are used in the construction.
Why do different suppliers offer different brightness for the same power?
Brightness depends on the quality and version of the LED chips used. Even with the same chip, different brightness bins can result in variations. It is important to distinguish between the raw LED lumens and the actual light fixture output.
What is color temperature (CCT)?
Color temperature is measured in Kelvin (K). Lower color temperatures (warmer light) are often used in public areas to promote relaxation, while higher color temperatures (cooler light) are used in offices or factories to enhance concentration.
What is CRI and why does it matter?
CRI (Color Rendering Index) represents how accurately a light source reveals the true colors of objects. A higher CRI provides more natural and vibrant color representation, which is essential for detailed work environments.
What are PF and efficiency in LED drivers?
PF (Power Factor) and efficiency indicate the electrical performance of the LED driver. Higher PF and efficiency ratings signify better energy utilization and higher quality components.
Is this UFO High Bay light waterproof for outdoor use?
Yes, this model features an IP65 rating, which means it is protected against dust ingress and low-pressure water jets, making it suitable for damp environments and various industrial applications.
