In the past, energy-saving light bulbs have been described as dim, slow to warm up and too cool in colour - but now they perform just as well as less efficient options. They’ll also save you a lot of money and hassle in the long run, so we’ve created a guide to the best ones on the market.


Types of energy-efficient light bulbs

These days, most people have replaced their old halogen bulbs for either CFLs (compact fluorescent lamps) or LEDs (light emitting diodes). In general, LEDs tend to be more practical than CFLs, as they’ll last roughly 2.5 times longer and don’t contain any toxic mercury, which can escape if smashed.

Here are some of the different types of energy-efficient light bulbs:

  • Dimmable/non-dimmable
  • Smart (control them via an app)
  • Fixing type: wide/narrow bayonet, wide/narrow screw
  • Shapes: traditional, globe, candle, downlight
  • Brightness: most bulbs have a rating between 450 and 1,600 lumens
  • Warmth: choose 2,700K for warm white or anything above 4,000K for daylight or cool white

The benefits of energy-efficient light bulbs

As energy-saving light bulbs use less power than inefficient alternatives, they can lower your household bills and reduce your carbon footprint. Plus, they can last for decades, so you won’t need to change them as often.

Let’s say you switch all the light bulbs in your home to energy-efficient ones. According to the Energy Saving Trust, you’d be decreasing your carbon emissions by up to 40kg per year - that’s 140 car miles. Your household bills could also reduce by up to £5 per bulb every year.

Philips Hue products are a solid choice if you’re upgrading your current bulbs, as the brand has released some of the most innovative lighting systems to reach the market. Its lightstrips can react to your Spotify music and even recreate the colours of your television as it plays.

This smart Edison-style bulb, on the other hand, is perfect for creating a warm, cosy ambience in your home. With its warm orange filament, it takes inspiration from vintage lighting.

Connect the bulb to the companion app to control it from any mobile or tablet, or use voice assistants. Just remember you may need a Philips Hue Bridge if you’re using certain Amazon Echo devices.

This may be the prettiest energy-efficient light bulb we’ve seen so far. A fluted amber glass globe serves the dual purpose of giving it a quirky vintage look and creating a pool of warm light.

You’ll get up to 15,000 hours of light from this non-dimmable bulb, which comes with an E27 connection. It gives out 120 lumens with a warmth of 1,800K, so it’s a cosy, low-level light, perfect for adding ambience, rather than lighting a whole room.

Sometimes, it pays to keep things simple, which is why we love this matt white globe. While bulbs with a visible filament hint at vintage style, opaque options like this are perfect for contemporary homes. Add them to rigid light fixtures like sputnik chandeliers for a clean, crisp look.

Another benefit of this globe-style bulb is its dimming function, which allows you to achieve the perfect level of lighting at any time.

With the bulb in place, you can set up colourful lighting landscapes and organise on/off schedules. Thanks to the bulb’s clever in-built technology, it can even fade up when your alarm clock goes off.

You’ll have the chance to get truly creative here, as Lifx’s dimmable bulbs can emit over a billion different colours, which you can select on the app’s colour wheel.

While some vintage-style bulbs come with straight filaments, these ones have a pretty spiral design inside. Mix and match the globe and teardrop designs above your dining table or breakfast bar to help create a relaxed atmosphere.
