This guide will give you the simple steps for choosing your perfect LED light bulb:

Bulb Shape

One of the biggest factors in choosing a bulb shape is personal preference, however some work better than others in certain situations. For example, chandeliers suit candle bulbs more than other types.

Lumens (Brightness)

LED Light bulb brightness is often stated in lumens (often shortened to lm). This information is available in the ‘Technical’ tab of all of our light bulb product pages.

With traditional inefficient incandescent bulbs of the past, brightness was predominantly gauged in watts. Modern efficient LED light bulbs also give a watt measurement, however because they are so efficient and the energy consumption (measured in watts) is very small, it can be difficult to relate incandescent watts brightness to LED watts brightness. Lumens are viewed as a more reliable measure for brightness of an LED bulb and the higher the number of lumens, the brighter the light.

What are lumens?

Consider where the light is situated and how bright the light needs to be.

Cap Size

Lightbulb fittings, also known as caps or bases, come in various shapes and sizes. The first step in any bulb purchase is to therefore identify the fitting type you need.

Colour Temperature

If you've been looking for LED light bulbs, you may have noticed that they often come with a colour temperature rating. This is in the format of a number, followed by a K, and occasionally with a description like Warm White. Like many people, you may be wondering what it means and which colour temperature you should go for.

The colour temperature of a bulb describes the appearance of its light. White is the common colour of light that most bulbs emit, but that white light can range from warm (a more orangey colour) to cool (a bluey white colour).

What is colour temperature?

Colour temperature is measured in degrees Kelvin on a scale from 1000 to 10000. So when you see the number 3000K or 4100K for example, the K stands for Kelvins.
