When upgrading your home's lighting, it’s easy to focus on fixture design or brightness levels. But one often-overlooked factor that makes a huge difference is color temperature. At Genesis Lighting, we help homeowners across Middle Tennessee choose the right LED lighting solutions—and understanding Correlated Color Temperature (CCT) is key to getting the look and feel you want.

What Is CCT?

Correlated Color Temperature (CCT) measures the appearance of light emitted from a bulb, expressed in Kelvin (K). The higher the number, the cooler (bluer) the light. The lower the number, the warmer (yellower) the light.

Common LED Color Temperatures:

2700K–3000K (Warm White): Cozy, relaxing glow – ideal for bedrooms and living rooms.
3500K–4100K (Neutral White): Balanced, clean light – great for kitchens and bathrooms.
5000K–6500K (Cool/Daylight): Bright, energizing light – perfect for garages, offices, and laundry rooms.

Why Color Temperature Matters

CCT affects both the mood of a space and how functional it is. Choosing the right temperature enhances your home’s atmosphere and helps each room do its job better.

Warm White makes spaces feel inviting and comfortable.
Neutral White provides clarity and focus without feeling harsh.
Cool Daylight boosts visibility for tasks like cleaning, working, or organizing.
