You may have heard of a term called Lumens, but what does this mean with regard to your lighting? Well, Lumens are simply a measurement of light! Historically, we became to rely on the ‘wattage’ of a bulb to indicate the brightness as we understood the variation of this measure, however, since light bulbs have become more efficient at giving out the same levels of light whilst using less energy and therefore less wattage, it is no longer a unit that is reliable in the measurement of light output. As a result, a new and uniformed measurement called Lumens was introduced.

The higher the lumens, the brighter the illumination from your bulb will be – a typical range would be from 400 lumens which is decorative, to around 1,000 lumens which is really bright – around the same as 100 watts in old money!

When LED’s first arrived, they were really quite dull, but now there is a huge variance of brightness on offer, some are really very bright indeed!

To help you understand a bit more we’ve put together a handy guide but in a nutshell, Wattage means how much energy your bulb uses and Lumens means the light you get. Each manufacturer will now show the lumens output on the packet – sometimes this can be abbreviated to just lm.

Along with getting the right brightness, there is other key information provided too, such as what colour of light it is, which is referred to as kelvins or colour temperature. You’ll also see the life expectancy of the light bulb, usually in hours and if it’s suitable for use with dimmer switches. It can all seem a little confusing at first, but once you understand these measures, you will reap the rewards from your lighting.

We have more videos on related subjects that are here to help you make confident decisions when choosing your bulbs and light fittings. We have energy labels on our website to inform you of their compatibility with different types of bulbs when you’re looking at buying a new light. The team and I are also available via chat on if you have a question about any of our lights.
