Your guide to E27 LED bulbs

Let us help you choose the right LEDs for your home. Our handy guide to E27 bulbs will give you everything you need to know to make switching over even easier.

What is an E27 LED bulb?

OK, so lets start with the basics. E27 bulbs are the ones with the screw base and are commonly used in decorative fittings and lamps. The key is to not get confused with E14 bases which are screw fit as well, but are built for smaller fittings. You can see the difference below:


What wattage do I need?

When you buy traditional halogen lights, you’ll be used to thinking of brightness in terms of wattage (the higher the wattage, the higher the brightness). With E27 LED bulbs, and all LEDs for that matter, you need to look at lumens instead of wattage. This is because, unlike halogens, LEDs use the majority of the power (wattage) for light, rather than losing much of it to heat. At LEDHut, we specify the rough lumen-wattage equivalents to make your decision easier.

What colour of light is best for me?

One of the big benefits of LED bulbs is that you have a number of different light colours to choose from, ensuring you have control over the ambience. LED colours are measured in Kelvins. The lower the Kelvin rating the warmer the glow, the higher the Kelvin rating, the whiter the light. You can buy E27 bulbs in 3 different colours: Warm White Cool White Daylight You can learn more about colour options here, and see which colour will look best in your home.

Will I need an electrician to fit these bulbs?

Absolutely not. Installing LED E27 bulbs is the same as standard E27 bulbs - you just screw them into the fitting.

What beam angle do I need? Beam angle is measured in degrees. A wider beam angle covers more space with light. Your choice of beam angle, like colour variant, is completely down to you. As a guide, we’d advise using wider beam angles in living spaces where many people are gathered round. Narrow beam angles, on the other hand, are often used for decorative purposes or areas where you need focus.

How much will an E27 cost me?

At LEDHut, we always strive to find a balance between good quality and affordable prices. Our E27 bulbs are designed to give you 25,000 hours of use and priced between approximately £6 to £14 (or £30+ if you want a specialist PAR-38 bulb). This may, on the face of it, look like a lot more than the halogen/incandescent bulbs you’re used to buying. But the amount you save on your energy bills far outweighs the up-front cost. In fact, you can expect payback on your small investment in just 6 months.
