Understanding Correlated Colour Temperature (CCT)
Correlated Colour Temperature (CCT) describes how the colour of light appears from a lamp, measured in Kelvin (K). It is widely used in LED lighting, LED panels, and commercial lighting to guide design choices for homes, offices, and retail spaces.

CCT is based on the principle of how heated metal changes colour with temperature — from red to yellow to blue — and has become a standard reference for describing the colour tint of white light from LED lamps.

Warm or Cool?
The choice depends on personal preference, application, and mood.
- Warm White (2700–3000K): Ideal for living rooms, bedrooms, and hallways. Popular in residential settings for its cozy, inviting glow.
- Cool White (4000K+): Modern and bright, perfect for kitchens, offices, retail, and task lighting. Higher lumen output makes spaces feel cleaner and well-lit.

In commercial applications, selecting the right CCT affects product presentation and customer experience. For instance, warm white lighting can enhance the appeal of baked goods, while cool white may be more suitable for offices or display areas.

Where to Use:
- Warm to Warm White: Living room, bedroom, hallway
- White to Cool White: Kitchen, study, bathroom, office, retail

- Daylight: Commercial spaces, retail, art studios

Mix and Match:
Combining warm white for ambient lighting with cool white for task lighting is common in offices and commercial spaces.

Choosing the Right LED Lamp:
Check the packaging and lamp base for CCT information, e.g., "3000K". Use the same LED model across a room for consistency, and consider buying spares, as LED technology evolves rapidly.
