What is Colour Temperature?

Colour temperature refers to the hue of the light emitted by a bulb, measured in Kelvins (K). It ranges from warm (yellowish) to cool (bluish) tones. Here’s a quick guide:

Warm White (< 3,300K): This light has a cozy, yellowish glow, perfect for living rooms, bedrooms, and dining areas. It creates a relaxing and inviting atmosphere.

Neutral White (3,300K - 5,300K): This is a brighter, more neutral white light, ideal for kitchens, bathrooms, and workspaces where you need good visibility and focus.

Daylight (> 5,300K): This light mimics natural daylight with a bluish tint. It’s great for basements, garages, and areas where you need bright, clear light for tasks.

Why Does Colour Temperature Matter?

Choosing the right colour temperature can significantly impact the mood and functionality of a room. For example:

Warm White: Best for creating a cosy and comfortable environment. Ideal for relaxing and unwinding.

Neutral White: Helps with concentration and productivity. Perfect for areas where you need to stay alert and focused.

Daylight: Energizing and stimulating. Great for detailed tasks and areas that need bright illumination.

How to Choose the Right Colour Temperature

When selecting light bulbs, consider the purpose of the room:

Living Room & Bedroom: Opt for warm white to create a soothing and inviting space.

Kitchen & Bathroom: Neutral white works well here, providing clear and bright light for tasks.

Home Office & Study: Neutral white or daylight can help maintain focus and productivity.

Garage & Workshop: Daylight is ideal for these areas, offering bright and clear light for detailed work.
