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 sa

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 a
reas to promote relaxation, while a cooler (higher color temperature) light is used to enhance concentratio
n 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
