FAQ

Q: Whether the  LED lights really have 50,000 hours lifespan?

A: 50,000 or longer lifespan is only theory from lab test.But due to working environment are different from 

in lab,actual lifespan is only  <=30,000hours. Meanwhile it can also be 50,000 hours lifespan if it adopt very good material.

Q: For same power,why different suppliers with different brightness?

A: Different chips,or same chip but different brightness version.The brightness will be different.But for same chip 

and same brightness version,the brightness will be slight difference.But please make clear the brightness difference 

between LEDs and lamp fixture.

Q:What is colour temperature?A: Kelvin is a way to measure "temperature", the light from LED lights emit a certain color, which we have catagorized 

in CTT(kelvin).For example, a warmer (lower color temperature) light is often used in public areas to promote relaxation, 

while a cooler (higher color temperature) light is used to enhance concentration in offices.

Q: What is CRI?

A: CRI is a figure which feedback the real objects colors.Higher CRI with higher cost.

Q: What is PF and efficiency?

A: PF and efficiency is to feedback the driver electrical performance.Higher PF and efficiency with higher coste other questions, please feel free to contact us, you will get reply at the first time
