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 street light 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.
