NETTA Christmas Tree Lights 200 LED 10m Fairy String Lights with Timer & Memory (Multi-coloured)

What these lights are for

NETTA’s Christmas Tree Lights are a plug-in set of fairy string lights designed to give your home or garden that “festive glow” without needing batteries or complicated set-up. As the name suggests, they’re aimed at Christmas-style decoration, but they’re also the sort of lights people use for weddings, birthday parties and general event backdrops.

On paper, what stands out is the combination of 200 LEDs, a fairly long run (10m), and a timer plus memory. That matters when you want the lights to look consistent each evening and you don’t want to keep switching modes back on manually.

The essentials: modes, spacing and control

You get 200 multi-coloured bulbs arranged so that they sit 5cm apart. That spacing is pretty key for a “full” look on a tree or along a display, because it reduces the chances of obvious gaps.

There are 8 lighting functions to choose from, controlled using a button on the plug adapter. The modes listed include: - Combination - Steady On - Slow Fade - In Waves - Slow Glow - Chasing/Flash - Sequential - Twinkle/Flash

The practical point here is not just variety, but convenience. You can switch effects with the plug-adapter button rather than reaching for the string itself each time.

Also included is a memory function, which should help if you tend to keep a favourite mode once you’ve found it. It’s not perfect for everyone—if you regularly want a different pattern on different nights, you’ll still be using the button—but for day-to-day festive use it’s more convenient than plain, single-mode sets.

Timer setting that turns itself on (and off)

This set includes a timer function intended to help with routine evening lighting. The instructions describe an 8-hour on / 16-hour off behaviour once the timer is enabled.

To activate the timer, you hold the power button for 3 seconds until the indicator turns green, then select your preferred lighting mode. To switch the timer off, you hold the power button for 3 seconds again until the indicator turns white.

Worth noting: timers like this are great for predictable “lights on at night” habits, but they rely on the way you set them up in your space (and whether your lighting setup is close enough to a power point). If you’re aiming for very specific schedules beyond the provided on/off cycle, you may find it a bit limiting.

Indoor and outdoor use, and what to check

NETTA states these lights are safe for indoor and outdoor use thanks to a low-voltage adapter and an IP44 rating (with the 31V low voltage adapter). There’s also a 5m lead wire to help with positioning.

If you’re planning outdoor displays—like wrapping around a garden feature or placing them where weather could reach—IP44 is a sensible starting point. Still, it’s wise to think about exposure: IP44 doesn’t mean “no worries in any conditions”, so if you’re dealing with heavy rain or harsh weather, you’ll want to position them thoughtfully and avoid unnecessary direct water contact.

What you’ll notice day to day

If you’ve ever bought fairy lights that are fiddly, these have a more straightforward approach: plug in, pick a mode from the adapter button, and use the timer if you want lights to come on automatically.

A simple micro-scenario: you set them on a porch rail or a Christmas tree, choose “Steady On” for a clean look during dinner, then later switch to an effect like “Twinkle/Flash” for the evening mood. The memory function should help you avoid re-selecting the mode every time you turn them back on.

Where they can feel a bit “average” rather than standout is in the broad multi-colour style. If you’re after a minimalist warm-white scheme, multi-coloured effects can look busy—so it may not match your interior aesthetic.

Who it suits (and who should be cautious)

It’s a good fit if you want Christmas tree fairy lights with a reliable plug-in setup, multiple effects, and a timer that runs for 8 hours before switching off. It suits people decorating for the festive season in a practical way—ready for indoor evenings, and also intended for outdoor decoration.

It might not be the best choice if you prefer a single colour temperature (like warm white only) or if you’re looking for a more premium, subtle look where multi-colour patterns won’t dominate. Also, if your power access is limited, check the lead wire distance (5m) before committing.

Buying verdict

For many households, these NETTA Christmas Tree Lights make sense because they combine 200 LED bulbs, 8 effect modes, and a timer with memory in a plug-in format that’s meant to be used both indoors and outdoors. The control-by-plug-adapter approach is the kind of small convenience that adds up over the season.

You should still think about your display plan—where the lead wire reaches, how exposed the area is, and whether multi-colour lighting fits your style. If those points line up, it’s an easy-to-live-with set for festive decorating and events.
