What is the difference between warm and cool light and when they should be used?

Warm and cool lights differ in their color temperature, which is measured in Kelvins (K). Warm light has a lower color temperature, generally around or below 3000K, and gives off a cozy, calm, inviting light similar to a sunset. It’s ideal for bedrooms, living rooms, or any space where relaxation and comfort are the goals.

Cool light has a higher color temperature, usually above 4000K. It casts a more energizing, crisp light similar to daylight, making it great for task-oriented spaces like offices, classrooms, garages, or any area where detail-oriented work is performed.
