Do the LED lights really have a 50,000-hour lifespan?
A 50,000-hour or longer lifespan is typically a theoretical value from laboratory tests. Due to varying real-world working environments, the actual lifespan may differ, but adopting high-quality materials ensures the best performance and longevity.
Why do different suppliers offer different brightness levels for the same power?
Brightness depends on the type of LED chips used or different brightness versions of the same chip. It is important to distinguish between the raw brightness of the LEDs and the actual output of the lamp fixture.
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 to enhance concentration in work environments like offices and factories.
What is CRI and why does it matter?
CRI (Color Rendering Index) is a figure that indicates how accurately a light source reveals the true colors of objects. A higher CRI provides more natural and vivid color representation.
What do PF and efficiency indicate?
PF (Power Factor) and efficiency reflect the electrical performance of the driver. Higher PF and efficiency values indicate better energy utilization and high-quality internal components.
What is the IP rating of this high bay light?
This light features an IP65 rating, making it dust-tight and protected against water jets, which is ideal for industrial environments like warehouses and factories.
