4000K Lights

4000K lights offer what many consider to be the ideal balance of cool and warm light. This makes them perfect for a variety of settings as they avoid the harshness of cooler lights (5000K-6500K) while providing better clarity and focus than warmer options (3000K). That means you can use 4000K lighting to create a bright, functional space without it feeling stark or clinical.
