Best outdoor lights

We put 11 outdoor garden lights, including icicle lights and fairy lights, through our tough durability tests to find out which are the most robust
Matthew Knight

Over the course of a couple of months we put 11 outdoor lights through an assault of durability tests to find the ones you'll be able to rely on all year round for many years to come.

The lights we tested range in price from £10 up to more than £60 (depending on how many metres you buy). We've tested mains-powered lights, battery-powered lights, icicle lights and fairy lights so that we can recommend the most durable sets, whatever your requirements. 

Surprisingly, fewer than half of the outdoor lights completely survived our durability tests. Clear signs of corrosion and poor soldering were the most frequent causes of early failure. Find out which lights suffered this fate.

How to pack up your lights after use

To keep long-lasting lights it's essential to store them correctly in any months when you might not be using them, making sure they aren't kept in a big tangled heap. 

  • Use a coat hanger: A spare coat hanger can be used to wrap your lights around. Not only does this stop them getting tangled up, but it minimises the space you need to store them as well. 
  • Wrapping paper tubes: You can recycle wrapping paper tubes and use them to wrap your lights around. Cut a slit in one end of the tube to grip one end of the lights, and then simply wrap them around the tube. 
  • Old cardboard box: If you don't have a wrapping paper tube, or a coat hanger, a similar method can be followed with a sheet of cardboard. Simply cut a notch at one end to attach the lights, and then wrap around the board. 
  • Light reels: If these homemade options don't appeal, you can buy light storage reels to help keep the lights tidy and stored correctly. We've seen them at a number of retailers, including Amazon, and retailers such as UKChristmasWorld or Festive-Lights, which will help keep the lights tidy and stored correctly. 

How we tested outdoor lights

We know from our research that outdoor lights have an issue with longevity. They simply don't last long enough, and many end up in landfill far too quickly. 

We set out to find out if there are outdoor lights that will survive tough British winters, and how much you need to pay for them. 

Of course we couldn't test these products over three or four years like we might like to - by the time we could publish the results you wouldn't be able to buy the lights anymore. 

So we designed a really tough set of tests to simulate the type of conditions these types of lights might endure over a harsh British winter. 


Each set of lights was subjected to a sustained shower with a hose, and then also fully submerged in a bucket of water for an hour. 

Subzero temperatures

Dripping wet, the lights were put into a freezer for 24 hours at -16 degrees. 


Before we even started the durability tests the lights were all left outside in all weathers for three weeks. This was enough of a test for many of the lights to already show signs of corrosion.

Rough treatment

We set up the lights, bashed them against fence posts and sharply tugged the wires repeatedly where they entered the plug socket and all along the cable. 

This tests simulated the type of rough treatment the lights might receive if they're being untangled, or put up without much care.
