Light Bulb Colour Temperature Chart

You’ll no doubt be aware that within a range of different lights, there will be some differences in their colour, often ranging from yellow to white. Various light bulbs actually emit light at different temperatures, which in turn affects the colour of the light itself. At Dusk Lighting we’re interested in getting to know the different light bulb colour temperatures and what that means for our lighting choices, so read ahead for more information.

What does light bulb colour temperature mean?

The temperature of a light generally refers to the ‘warmth’ and ‘cool’ colour tones emitted by a light bulb. The warmth encompasses yellow and cool refers to a blue light, though this shouldn’t be confused with the measurement of brightness which is in determined by lumens. There is a light bulb temperature recording scale called the Kelvin Scale which allows the light bulb temperature to be measured in ‘Kelvins’ or K for short.

The Kelvin Scale – A light bulb colour temperature chart

As you can imagine, there’s a huge scale in which temperature colours are measured on the official Kelvin scale, but it is generally agreed that there are roughly three variations to determine light temperature by.

Warm white

You can expect this 2000-3000k warm white colour from standard incandescent light bulbs that are traditionally used in pendant lights and table lamps in the home. The warm white has a yellow hue to it, making it a good option for spaces of relaxation such as bedrooms and living rooms.

Cool white

This light bulb temperature at 3100-4500k is a great option for ‘task lights’ and where we require higher levels of illumination, or even accent lighting in and outside of the home. When it comes to installing cool white light bulbs in home light fittings, opt for these lights as your kitchen lighting and bathroom lighting.

Cool daylight

For those affected by Seasonal Affective Disorder (SAD), a lamp that replicates cool daylight has been said to work wonders during the darker months where natural daylight is limited. In those situations, it is recommended that a bedroom lamp which emits a temperature of 5000-6000K with a cool blue hue may work well. Daylight light bulbs are also ideal as security lighting for safety purposes.

Why does the temperature of a light bulb matter?

It’s important to be aware of the light bulb temperature so that you can have an enjoyable lighting setup in your home, and one that is consistent with the needs of each room. The warmth of your lights can have a profound effect on the look and feel of a room, so it makes sense to have one particular temperature for all of the lights in one room, such as the lounge.

The light bulb temperature is also an element to consider when buying replacement light bulbs for your lights, so it’s a good idea to note down the K measurement before ordering or purchasing new bulbs.

Which light bulb colour works best?

Not all light bulbs will work well in every room of the home, which is why it is helpful to get to know the various colour temperature options and make an informed decision on which light bulb to choose.

For lights in the bedroom and lounge, it makes sense to choose a light that will emit a warmer light for that welcoming ambience and relaxation effect. We recommend choosing a warm tone light for your bedroom lighting and lounge lighting, and this light will work really well with dimmable light fixtures.

When it comes to lighting a kitchen or bathroom, white lights may be the best option to give that bright illumination we seek for our kitchens and bathrooms. Energy saving lights often burn at a temperature of 3500k in a white colour, so it is worth looking into switching to energy efficient kitchen lighting as a way of reducing your energy bills and helping the environment.

With Dusk Lighting there are so many affordable lighting options to choose from, and with our range of light bulbs, you’re able to select the right colour temperature to suit your home lighting needs.
