Here are some frequently asked questions by our customers

What is the benefit of 4000K light bulbs?

4000K light bulbs give off what’s known as a “cool white” light. They help you focus, which is why they are often chosen for workspaces, kitchens, garages and bathrooms. They’re ideal for task lighting and make colours appear more vibrant. They also tend to be more energy-efficient, which means lower running costs.

Are 4000K light bulbs suitable for every room?

While personal preference plays a big part, some people might find that 4000K light bulbs are too bright for living rooms, dining rooms, or bedrooms where a more relaxing ambience is usually preferred. If that sounds like you, you’ll be better off with 2700K-3000K bulbs.
