Whether the LED lights really have 50,000 hours lifespan?
50,000 or longer lifespan is only theory from lab tests. Due to different working environments, the actual lifespan is typically <=30,000 hours. However, it can reach 50,000 hours if high-quality materials are adopted.
For the same power, why do different suppliers have different brightness?
Brightness varies due to different chips or brightness versions of the same chip. Please distinguish between the brightness of individual LEDs and the overall lamp fixture.
What is colour temperature?
Measured in Kelvin (K), it categorizes the color of light emitted. Lower temperatures (warmer) promote relaxation in public areas, while higher temperatures (cooler) enhance concentration in offices.
What is CRI?
CRI (Color Rendering Index) represents how accurately a light source reveals object colors. A higher CRI typically results in a higher cost.
What is PF and efficiency?
PF (Power Factor) and efficiency reflect the electrical performance of the driver. Higher PF and efficiency ratings generally indicate better quality and higher cost.
How do I choose the right projection distance?
The projection distance is determined by the beam angle (10° to 90°). Narrower angles are ideal for long-distance focus in large stadiums, while wider angles suit broader lighting applications.
