NETTA Christmas Tree Fairy Lights (200 LED, Cool White) – 8 Lighting Modes for Indoor/Outdoor Use
Product description
What it is and why people buy it
NETTA’s Christmas Tree Fairy Lights are a plug-in set of cool white LED fairy lights designed to give you a festive glow around the home or outside for gatherings. With 200 LEDs and a stated 20M lit length, they’re aimed at people who want that classic twinkly look without having to deal with batteries or complicated installation.
On paper, they’re built around two practical priorities: simple operation (plug in and choose a mode) and flexibility for common seasonal setups, from wrapping around décor to adding sparkle in a garden feature. They also include memory via the modes, so you don’t necessarily have to cycle through everything every time you turn them on.
A quick micro-scenario: imagine arriving at a Christmas party and wanting lights that instantly look “done”. You plug them in, press the mode button on the adapter until you get something like Twinkle/Flash or In Waves, then step back and adjust positioning—no fiddling with battery packs or remote app.

The essentials: modes, spacing and the overall look
These lights offer 8 different functions: Combination, Steady On, Slow Fade, In Waves, Slow Glow, Chasing/Flash, Sequential and Twinkle/Flash. The modes are controlled from a button on the plug adapter, which is a straightforward approach if you’re choosing effects during setup rather than constantly switching them.
The bulbs are spaced 10cm apart. That spacing matters because it affects how continuous the light coverage looks from typical viewing distances. If you want a noticeable decorative “line” of light, this spacing is generally the kind of detail that helps avoid big gaps—though, as always, results depend on how and where you hang or wrap them.
You’re also choosing cool white specifically. That tends to read as crisp and bright rather than warm and cosy, so it suits modern Christmas styling, certain outdoor scenes, and anyone who prefers a cleaner look.



What stands out for indoor/outdoor use
A big selling point here is that the lights are stated to be safe for indoor and outdoor use thanks to a low-voltage adapter (31V) and an IP44 rating. IP44 generally signals splash/dust resistance for outdoor use in typical conditions, which is the kind of reassurance you want if you’re putting lights near doors, garden décor, or outside along a pathway.
They’re mains-powered via a UK plug, with a 5M lead wire for installation. The lead length is worth thinking about: if you’re planning a longer run from your nearest socket, you may need careful placement to avoid over-stretching or relying on extension leads.
Quick practical considerations before you buy

It’s not a complicated product, but there are a couple of “keep expectations realistic” notes.
First, the stated 20M lit length is helpful, yet the final coverage will depend heavily on your decoration plan and how tightly you space or wrap the strand. If you’re picturing a dense blanket of light across a wide feature, you might find you need more than one strand or more planning time.
Second, cool white plus effect modes is a style choice. Some people love the motion effects, others prefer Steady On for calmer ambience. If your priority is a subtle, low-key glow, the more animated modes may feel a bit busy for everyday use.

Where it makes sense (and where it may not)
It’s a good fit if you want plug-and-play Christmas lights with multiple effects, a cool white look, and the option to use the same set indoors and outdoors without swapping to a battery system. The IP44 and low-voltage approach are particularly relevant if you’re setting up around the garden or near external areas.
It might not suit you if you’re after warm white ambience, or if you need extremely dense coverage with minimal spacing. Also, if your socket is far from where you want the display, the 5M lead wire may be a limiting factor—so it’s worth checking your layout before you commit.

Is it worth it?
If you’re looking for Christmas fairy lights that are easy to run (no batteries), offer 8 modes, and are specifically positioned for both indoor and outdoor decorating, these NETTA lights make practical sense. The cool white effect styles can look punchy outdoors, while Steady On and slow effects tend to work well indoors when you want something less hectic.
However, you’ll get the best results when your decoration plan matches the provided coverage (10cm bulb spacing across a 20M lit run) and when the 5M lead wire can reach comfortably from your power point.
