Lower colour temperature implies warmer light while higher colour temperature implies a cooler light. Standard unit of colour temperature is Kelvin(K). For example, usually colour temperature of incandescent lamps is 2700-3000K; daylight fluorescent lamps are 5500-6500K.
WARM WHITE 3000K
A comfortable white color that is used in living areas and residential applications, where timber or darker floors are present. It is what we are used to in Australian households. Due to its Yellow / Orange output, it creates a relaxing atmosphere. This makes it suited for bedrooms and living rooms.
NATURAL WHITE 4000K
Artificially whiter light. It’s a suitable middle ground between daylight and warm white, this makes it suitable for most flooring such as wood, carpet and stone. It’s suited for bathrooms, pantries and work areas.
DAYLIGHT / COOL WHITE 5000K
Less commonly used in residential applications, it’s more designed for commercial applications, like retail and offices, due its intense light output, which is designed to assist in focus. This light is also used where there is a high prominence of the colour white, for example white tiles.
