How to choose the right color temperature?

4000-4500K——Classroom, library, laboratory , workshop, office and meeting room, etc.

3000-4000K——Studio, activity center, union room, stadium, etc.
When those who works on creative orientation or takes part in activities, the 3000-4000K color would not only inspire their creativity but also help them relaxed after busy working days.

2800-3500K——shopping mall, boutique, restaurant, hotel, home, etc.
On the one hand, easy and cozy environment with soft color would make customers enjoy their shopping. On the other hand, the warm white color with focus lighting would attract their eyes on goods and then stimulate customers’ consuming desire.
While in restaurant, hotel or at home, where we have a rest, 2800-3500K color definitely makes you forget fatigue.
