When you are looking to get a replacement bulb, the chances are that you are asked what colour you’d like. Well, the majority of bulbs are white, so most of the time you’ll choose a white one! But there’s more than one white on offer and it’s referred to as colour temperature…. So what does the colour temperature of bulbs mean?

Bulbs now come with a rating to indicate the colour of the light that your bulb emits. The white tones can be placed on a scale ranging from a candlelight to a cool white and we can measure it on a scale referred to as Kelvin.

Towards the lower end of the scale are the warmer, candlelight style tones which would be ideal for decorative lighting and adding warm ambience to a room.

The next stage up the scale is referred to as ‘warm white’ and this is what most of us will already be utilising in our living rooms, dining rooms and bedrooms. Whilst still offering a warm, atmospheric glow, you will find it better suited for reading and other relaxing tasks.

At the higher end of the scale we come to the cool whites and this is a crisp, invigorating light most suited to bathrooms and kitchens where a cooler, brighter light is required. They would also be ideal in areas with limited daylight, such as garages and cellars and are often used in home offices, display areas, security and task lighting.

In essence, the higher the kelvin rating of the bulb, the cooler and brighter your light will be and the lower the rating you’ll see the softer warmer tones. So, next time you choose a replacement bulb, make sure you choose the best colour temperature for your room as it really does makes a huge difference to the effect your lighting has.

If you are still unsure which you need, or if you have a room used for both work and relaxing, you could always opt for an LED smart bulb as this allows you to change the effect at a press of a button or even via an app! There’ll be more about this on another video.
