We compared two battery fairy lights: the Kolpop 4 Pack 5m 50 LED Fairy Lights and the Ollny 10m 100 LED Fairy Lights.
What we looked at
Number of strings, total length, modes, timer, weatherproofing, and price.
The verdict
If you want four separate 5m strings with a 6 hours on, 18 hours off timer, the Kolpop 4 pack is the pick at £9.98. If you would rather have one 10m string of 100 LEDs with 8 modes and an IP44 rating, the Ollny is the alternative, at £9.99, a penny more.

A £9.98 pack of four 5m strings, 50 warm white LEDs each, with a timer.

A £9.99 single 10m string of 100 LEDs with 8 modes and timer.
