Knayis 50LED Solar Fairy Lights (7m/23ft) – Outdoor Waterproof String with 8 Lighting Modes
Product description
What these solar fairy lights are for
If you’re after garden lighting that looks decorative without the hassle of mains wiring, these Knayis 50LED solar fairy lights are built around that exact idea. The set uses a long string of LED crystal-style “bulbs” (50LED total) and is designed for outdoor spaces like patios, lawns, porches, terraces, and event setups.
On paper, the appeal is simple: you hang the lights, put the solar panel in direct sunlight, and let them do the rest. They’re also aimed at people who want a bit of mood control, thanks to 8 lighting modes (from steady light to twinkle-style effects). That makes them feel more flexible than basic solar strings that only do one look.
That said, solar lighting always depends on location and sunlight. If your garden is shaded most of the day, you may find performance varies.
Key features at a glance
The practical headline here is the length and control. The string light measures 7 metres in total, including a 2 metre lead wire, which helps when you’re trying to reach from the mounting spot to where the decorative effect is needed.
You also get 8 lighting modes: Combination, In Waves, Sequential, Slo-Glo, Chasing/Flash, Slow Fade, Twinkle/Flash, and Steady on. In real-world terms, that means you can adjust the vibe between “calm background glow” and “more noticeable party lighting”, depending on what you’re doing.
For power, the lights use upgraded solar panels and a built-in 800mAh high-capacity battery (as stated). The manufacturer also claims an efficiency improvement with the solar cell technology, and it includes an auto on/off behaviour: the set turns off after 8 hours of illumination, triggered by a light sensor.
What you’ll notice day to day
Charging and evening runtime
The lights are meant to charge during daylight. The guidance given is that a 3–5 hour charge in good conditions should provide 10–12 hours of nighttime lighting. There’s also a claim that even on cloudy days with insufficient sunlight, the lights can still deliver 8 hours of lighting the next day.
It’s worth noting that this is still “solar” at heart—your results will depend quite a lot on how much direct sun the solar panel actually receives.
Automatic on/off
Because the system is sensor-driven, you don’t need a timer or manual switching as such. Once placed in direct sunlight, it should automatically switch on at night. For many people, that convenience is the whole point of buying solar fairy lights in the first place.
Weather resistance (IP65)
The set is rated IP65 waterproof (with multiple waterproof tests claimed). In everyday use, that means you can leave them out for typical rain and damp outdoor conditions without treating them like something that must be stored away at the first drop.
Choice considerations before you buy
If you’re thinking about whether these Knayis solar fairy lights are worth it, here are the limitations to keep in mind.
- Solar dependence is real. Even with the claimed cloudy-day performance, solar strings can underperform in consistently shaded spots.
- Outdoor use is covered, but setup still matters. You’ll want to position the solar panel where it gets direct sun. Putting it behind walls, under trees, or in a shady corner usually defeats the purpose.
- Modes are fun, not everything. The 8 modes add variety, but if you mainly want a single steady light for ambience, you’ll still need to confirm the steady mode is the one you’ll actually use most.
Who they suit (and who might skip them)
It’s a good fit if you’re decorating an outdoor area for day-to-day ambience, such as a patio or porch, and you’d rather avoid extension leads or outdoor mains power.
It also makes sense for occasion lighting—weddings, garden parties, camping-style setups, or a temporary yard decoration—where the ability to change lighting modes can help you match the mood.
You may want to skip these if your outdoor space is heavily shaded, if you need reliable brightness for long winter evenings regardless of weather, or if you’re expecting the lights to behave like mains-powered strings (they won’t).
Getting the most from them (practical tips)
Before hanging, choose where the solar panel will live. Even if you love the look of the string, a poor panel position can lead to short runtimes.
A simple example: for a patio, mount or place the solar panel in direct sun at one end of the area, then drape the 7-metre string along the railing or around a pergola line. In the evening, start with Steady on or Slo-Glo for dinner, then switch to Twinkle/Flash for guests. That way the modes actually serve the event rather than becoming an afterthought.

Final verdict
Should you buy it? These Knayis solar fairy lights are a sensible choice if you want decorative outdoor lighting with 8 lighting modes, a 7-metre run that includes a lead wire, and IP65 waterproofing for typical rain and outdoor use. The auto on/off approach and the claimed charging-to-runtime guidance make them feel practical for most home garden setups.
But if your main priority is consistent brightness no matter the season or cloud cover, you may find solar lighting a bit too variable. In that case, it could be better to consider a mains-powered approach instead, where runtime doesn’t hinge on sunlight.
