It would also be a good idea to buy spares – as LED technology (as with other technologies such as mobile phones) is always improving and changing.Tunable-white lighting is a popular trend in both commercial and residential lighting. " 3000K".ĭue to variations in the manufacturing process and different measurement methods you should consider buying the same model of LED lamp for all the fittings in an area or room. In addition, each lamp will have the colour temperature printed on the base e.g. How do I know which one I am buying?Īll Integral retail packs have a clear icon and colour temperature indicated on the packaging. You can see this in action with our Colour Switching Fire Rated Downlight. New LED technology from Integral LED allows you to switch between 3000K (Warm), 4000K (Cool White ) and 5000K (Daylight). Have the best of all worlds with Colour Switching downlights! For example, warm white for the main room lighting and cool white for task lighting over work areas. There is no reason why you could not have a mixture in the same setting. Daylight - Commercial, retail, art studiosĪllow some time to get used to any change especially if changing from warm to cool white.White to Cool white – kitchen, study, bathroom, cupboard, office, retail.Warm to Warm white – living room, bedroom, hallway.Where can I use them?īelow are some common areas where the different colours can be used: 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. 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.
It also seems people from sunnier countries tend to prefer white light compared to people from cooler countries who prefer more warm light. 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). If you want a modern, clean look, you may prefer the cleaner, brighter feel of a cool white lamp (4000K+). 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. There are no rules - the choice is about personal preference and use. The colour of light from an LED lamp is approximated or “correlated” to this scale. This range of colours at different temperatures has become useful for describing the colour tint of white light. You can then determine the temperature of a heated metal by its colour. Put simply, colour temperature is based on how the colour of heated metal changes as its temperature is increased - turning from red to yellow then blue. KelvinsĬonventional Halogen and LED Lamp - Yellow The higher up the scale you go, the closer the light resembles blue daylight.Ĭonfusingly, 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. Imagine a scale from 1000K (very red) to 10,000K (very blue) (actual scale is wider). With some LED products, there is a choice of colours, and choosing a colour will set the mood of your space.Ĭorrelated Colour temperature (CCT) in lighting describes how the colour of the light appears from a lamp, measured in kelvins (K). With conventional lamps, choosing the “colour of light” emitted by a lamp was not a choice that was generally made. This article will help you understand what is meant when LED lamps are referred to as being either "warm" or "cool".
