We review 14 LED light bulbs (or lamps, as they're technically called) of the type used in most household light fittings. This test includes light bulbs with wattages from 8.6W (watts) to 14.2W and light output from 600lm (lumens) to 1055lm.

These light bulbs have been on test for nearly 14,000 hours. Because of the time it takes to test light bulbs, most of these are now superseded by newer versions. For that reason we haven't recommended any of these models, but their performance is a guide for what you can expect from similar models from the same brands.

You can also see our free articles giving an overview of what our long-term testing has found about LED light bulbs (are those long lifespan claims realistic?), our light bulbs buying guide and for the technically-minded, how we test light bulbs.

This batch of lights was tested for 13,800 hours – the equivalent of seven and a half years of use, assuming five hours' use per day.

In this review we'll tell you:

  • what to buy
  • which models meet their claimed light output
  • which models are still going strong after 13,800 hours.

Our interactive comparison tool helps you see at a glance good and bad points for each light bulb, along with features such as whether they're dimmable and their shape and size.
