Frequently Asked Questions
Do the LED lights really have a 50,000-hour lifespan?
A 50,000-hour or longer lifespan is a theoretical value from lab tests. Due to different real-world working environments, the actual lifespan is typically >=30,000 hours. However, it can reach 50,000 hours if high-quality materials are adopted.
Why do different suppliers provide different brightness for the same power?
This is due to different LED chips or different brightness versions of the same chip. Even with the same chip, slight differences exist. It is important to distinguish between the brightness of individual LEDs and the overall fixture.
What is color temperature?
Color temperature is measured in Kelvin (K). Lower color temperatures (warmer light) are used in public areas for relaxation, while higher color temperatures (cooler light) enhance concentration in offices or sports venues.
What is CRI?
CRI (Color Rendering Index) represents how accurately the light reflects an object's real colors. A higher CRI provides better color accuracy but often comes at a higher cost.
What are PF and efficiency?
PF (Power Factor) and efficiency represent the electrical performance of the driver. Higher PF and efficiency values indicate better quality and energy usage, usually resulting in a higher cost.
Is this light suitable for extreme outdoor conditions?
Yes, with an IP66 rating and a working temperature range of -30ºC to +50ºC, these lights are specifically designed for harsh outdoor environments like sports stadiums and industrial sites.
