Find out everything you need to know when choosing a light source for your new designer lamps. We have created a simple guide to help you achieve the perfect light for your home.
Choosing the right light source can be challenging in a world of unfamiliar terms and technical jargon. This guide will help you make the right choice for your lamp, including what to consider when selecting a light source and what to look for in lamps with integrated LEDs.
Colour Temperature (Kelvin)
Kelvin describes whether the light feels warm or cool.
2200K = Extra warm, soft glow
Best for bedrooms and cosy spaces
2700K = Warm white light
Best for living rooms, dining areas and kitchens
3000K = Clearer white light

Which Bulb Should You Choose?
Many lamps use replaceable bulbs such as E14, E27 or GU10, while others include integrated LED.
We recommend LED bulbs for most homes thanks to their:
Low energy use
Long lifespan
Warm light options
Dimmable versions available
