Light ‘Colour’
When you are buying a light bulb you may have noticed the box says things like “Warm White” or “Daylight White” but what does it mean? . . . . . . and which should you buy?
Colour Temperature
Light colour is measured using the ‘Colour Temperature’ and is quoted in Kelvins (K).
A higher Kelvin temperature means the colour is cool. while lower K temperatures are warmer colours. (No wonder it can be confusing!)
For domestic lighting you should be looking for lights in the range from 2700K to 5000K.
Light Colour Options
Within the range 2700K to 5000K there are three options of colour temperature to choose from:
- Warm White – 2700K to 3500K Has a slight yellowish tint which gives a relaxing and calming light. Good for bedrooms, living rooms, and dining rooms.
- Natural White – 3500K to 4500K Closest to sunlight, which makes it good compromise for any location, but particularly; walk in robes, pantries, garages and other areas that don’t have a lot of natural light.
- Daylight White Light – 5000K to 6000K A slight blueish tint provides a crisp and bright white light that helps you feel more alert. Good for the home office or workshop.
En Suite / Bathroom Light
I know there are a lot of ladies out there who want to be sure their appearance is just right. To help with this the light on the make up mirror should be appropriate for the lighting you will encounter over your day.
If you mainly work in an office or brightly lit factory Daylight White may be the best choice. . . . Otherwise Natural White is a good option.
