Colour Temperature

Colour temperature is measured in Kelvin (K) – the lower the number, the warmer the white light appears, while a higher Kelvin will appear cooler. Colour temperature generally ranges from 2700-3300K (warm) to 3300-5300 (cool) – and 6500K is daylight.

There is equivalent wattage between different light bulbs. To stop making confuse, you need to know what wattage equivalent to each other. See the table attached as below.

The 6500K Daylight version produces a crisp, bright white light ideal for task lighting, retail displays, kitchens, and commercial applications where maximum visibility and clarity are required. The 3000K Warm White version produces a softer, warmer light better suited to living areas, hospitality settings, and accent lighting where a relaxed, inviting atmosphere is desired.
