Kelvin (K) indicates the color of light emitted by an LED. Lower Kelvins (e.g., 2700K) produce warm, yellowish light, while higher Kelvins (e.g., 4000K+) result in cool, bluish light.

The color temperature you choose should reflect your personal preferences and the specific location where you'll be using the light.
Warm white creates a cozy atmosphere, while cool white is more energizing and better for tasks. Your choice depends on the mood and functionality you want.
