Frequently Asked Questions
Do LED stadium lights really have a 50,000-hour lifespan?
A 50,000-hour lifespan is the theoretical result of laboratory testing. In actual working environments, lifespan typically averages around 30,000 hours, though it can reach full theoretical limits if high-quality materials and optimal conditions are maintained.
Why do different suppliers offer different brightness for the same power?
Brightness varies based on the LED chips used or different brightness versions of the same chip. Performance is also determined by the difference between individual LEDs and the final lamp fixture efficiency.
What is Color Temperature (CCT)?
Color temperature is measured in Kelvin (K). Lower color temperatures (warmer light) are often used for relaxation in public areas, while higher color temperatures (cooler light) enhance concentration in offices or sports venues.
What is the significance of CRI?
The Color Rendering Index (CRI) represents how accurately a light source reveals the true colors of objects. A higher CRI provides more vivid and natural color representation.
What are Power Factor (PF) and efficiency?
PF and efficiency indicate the electrical performance of the LED driver. Higher PF and efficiency ratings result in better energy savings and overall product quality.
Can these lights be used in heavy rain?
Yes, with an IP65/IP67 rating and specialized waterproof housing, these lights are designed to function reliably in outdoor environments and wet weather conditions.
