Warm White or Cool White? | Integral LED
Choosing warm white or cool white lamps & lightbulbs for your house or business comes down to personal preference and the atmosphere you want to create. Confusingly, colour temperature does not describe the actual temperature of the lamp itself but the colour it produces and counter-intuitively; the higher the colour temperature the “cooler” a lamp will look.If you like the traditional yellowish colour of a conventional lamp then warm white around (2700-3000K ) would be the ideal choice, this is the most popular choice for homes. If you want a modern, clean look, you may prefer the cleaner, brighter feel of a cool white lamp (4000K+).Cool white light contains more blue light and looks brighter to the eye (this is why cool white bulbs have a higher lumen output when compared to the equivalent warm white bulb). It also seems people from sunnier countries tend to prefer white light compared to people from cooler countries who prefer more warm light.In commercial applications choosing the right colour temperature is important and will depend on the mood you want to create and the products you are promoting - for example freshly baked cookies and bread may look better under a warm white light. A cool white light may not make the product look as appealing but it would be a good idea to do some trials to see what works best.
