Light bulb color temperatures typically fall between 2,500K and 6,500K.

Soft white is warm and, as the name implies, softer, while daylight is cool and bright.

Soft white bulbs also work in spaces withwooden floorsor cabinets.

They’re also good for bedside or table lamps since they allow for visibility without much brightness.

They may be too dim for active spaces or spots where limited visibility would be an issue.

And if you want to stay alert and focused, warm bulbs give the opposite effect, encouraging relaxation.

The bright light of cool white bulbs is also stimulating, providing a less cozy environment.
