Many customers will confuse what is the color temperature difference between LED T8 fluorescent tube lamp lighting with Traditional fluorescent lamp. In traditional fluorescent lamp, there are 3 colours, 3000K-Warm White,4100K-Cool White; 6500K-Daylight. But in Led T8 fluorescent tube lamp lighting, the definition is different. Because in one LED T8 fluorescent tube lamp lighting, it has many pieces LEDS, the color temperature cann't be all the same, so you need to offer a color temperature section in purchasing Led T8 fluorescent tube lamp lighting. Below is definition which accept by many Led T8 tube manfacturers
2700K-4000K warm white.
4000K-5000K middle , some factory may call it warm white or others may call pure white
5000K-6000K Pure white.
6000K-6500K middle , some factory may call it Pure white or others may call Cool white.
6500K+ Cool white.
Certainly it may a little difference between different factory, but above definition is accept by most factorys.
So when you purchase Led T8 fluorescent tube lamp lighting, it is not a correct way to tell supplier that you need warm white or Pure white. It would be better to tell supplier that the color temperature sections you need, orelse you have to accept factory standard.
