When it comes to lighting, one of the most overlooked—but most important—factors is colour temperature. Whether you're designing a cozy living room, lighting up a workspace, or shopping for bulbs online, knowing the difference between warm and cool light can make all the difference.
What Is Colour Temperature?
Colour temperature is measured in "Kelvin (K)" and describes the appearance of the light produced by a bulb. The higher the number, the cooler and bluer the light. The lower the number, the warmer and more yellow or orange it appears.
- 2700K–3000K – Warm White (great for living rooms, bedrooms, restaurants)
- 3500K–4100K – Neutral or Cool White (perfect for kitchens, bathrooms, and workspaces)
- 5000K–6500K – Daylight (ideal for garages, basements, offices, or any task-oriented environment)
Why Does It Matter?
The right colour temperature can:
- Influence mood and comfort
- Improve focus and productivity
- Make your space feel warmer, cleaner, or more vibrant
For example, a 2700K bulb in a reading nook feels inviting and soft, while a 5000K bulb over your workbench keeps everything crisp and clear.
Choosing the Right Colour Temperature
- For relaxing spaces like living rooms and bedrooms: stick with warm white (2700K–3000K)
- For kitchens, laundry rooms, and bathrooms: neutral white (3500K–4100K) adds clarity without feeling too harsh
- For garages, offices, and task lighting: daylight (5000K+) improves visibility and alertness
Adjustable or Tunable Options
Many newer LED fixtures and bulbs now come with 'adjustable colour temperatures', meaning you can choose or switch between several Kelvin values using a dial or remote.
This is a great choice if you're unsure what you prefer—or if you want one fixture to serve multiple moods or functions.
Final Thoughts
Lighting isn't just about brightness. It's about feeling, function, and focus. Choosing the right colour temperature helps your space do what it's meant to do—and helps you feel better in it.
