TANSOOL+ 40cm Under-Cabinet Kitchen Lights (Motion Sensor) – USB-C Rechargeable LED, 2 Pack
Product description
The essentials
If you want some extra light under kitchen cabinets, in a hallway, or along the stairs without running cables, the TANSOOL+ under cabinet lights are built around that exact idea. They’re rechargeable, designed to stick or magnet on depending on your surface, and they can turn on automatically when they detect motion.
On paper, this is the kind of lighting that makes everyday movement feel safer and more convenient—especially at night, when fumbling for switches is annoying rather than “romantic”. The dimming is also handy if you don’t want full brightness every time.
That said, like most rechargeable LED solutions, it’s worth thinking about how often you’ll use the motion mode versus leaving the lights on constantly. If your usage pattern is very heavy, battery runtime becomes the main thing to check.
Key features you’ll actually notice
The big selling points here are the dimming, the built-in motion sensor behaviour, and the no-wiring installation approach.
Dimmable natural white
The lights use a natural white tone at 4000K. Brightness can be adjusted in steps (10%, 25%, 50%, 75% and up to 100%) using a short press. This is useful because under-cabinet lighting often gets used in different settings: food prep might need higher brightness, while walking through a dark hallway usually doesn’t.
A frosted cover is included to reduce glare, which matters more than you’d think if the light source faces towards your eyes.
Four operating modes for daytime and night-time
Beyond “always on” and “always off”, there are two sensor modes: - All Day Sensing: lights up when motion is detected. - Night Sensing: lights up only when motion is detected in dim environments.
In real life, the Night Sensing mode can be a nice way to avoid lighting up every time there’s movement in a room that’s already bright.
Motion sensor coverage
In motion sensor mode, they activate when motion is detected within 3m (10ft) at a 120° angle. Once motion stops, they switch off after 20 seconds.
That 20-second delay is a sensible compromise: it gives you time to walk past, without leaving the lights on for ages.
What to know about installation and placement
These are designed to be installed quickly.
The lights include powerful built-in magnets for mounting on any metal surface without damaging it. If you’re working with a non-metal surface, you’re meant to use the included adhesive metal plate, and then attach the lights to that.
There’s also a practical benefit: when you need to recharge or move them, you can take the cabinet lights off. So you’re not stuck in place once they’re mounted.
One limitation to keep in mind: if you don’t have suitable metal surfaces and you’re not confident with adhesive mounting, you may want to think through where the adhesive plate will go and how clean the surface needs to be for reliable sticking.
Battery life and charging—where the trade-offs show
Charging is via USB-C, with a built-in 2200mAh battery. The lights are described as fully charging in 3 hours.
The runtime is estimated as: - Up to 5 hours on “on mode” - Up to 3 months in sensor mode, based on 10 activations per day
Those numbers are useful for planning, but they also highlight what matters: motion mode is typically the efficient setting, while always-on will drain the battery faster. If your main goal is continuous illumination (for example, keeping under-cabinet lighting on for long periods), these may feel more like a “top-up lighting” solution than a permanent wired replacement.
Where they fit best (and where they might fall short)
It makes sense if
It’s a good fit if you want portable under-cabinet style lighting that you can install without wiring, and you prefer motion-activated convenience in areas like:
- kitchens where you want light while cooking
- bedrooms and wardrobes where you don’t want to reach for a switch
- hallways and stairs where hands are often full
You’ll also like the dimming if you’re trying to avoid harsh lighting at night.
It may not suit you if
It might not be a great match if you’re expecting this to behave like hardwired lighting that you can forget about. Since it’s rechargeable, your routine will matter—especially if you mostly use “always on”.
It also may not be ideal if your installation surface plan relies heavily on adhesive and you’re not sure you’ll be happy with that placement long term.
Practical example: evening use
Imagine you come downstairs at night. You’d set the lights to motion sensor mode, ideally using Night Sensing for dim environments. As you walk beneath or near the cabinet line, the light detects your movement and turns on instantly. When you’ve passed and there’s no motion for 20 seconds, it switches off again, helping prevent wasted battery and reducing glare while you move through the space.
That’s the kind of everyday workflow this set is designed for.

Buying verdict
Is it worth it?
Worth considering if you want under-cabinet lighting with motion activation, dimming control, and a no-wiring install using magnets or an adhesive plate. It’s particularly compelling for wardrobes, hallways, and stairs where the motion sensor behaviour and the glare-reducing frosted cover can make daily movement feel easier.
Better avoided if you need long periods of constant light and can’t manage recharge timing, because “on mode” runtime is limited compared with sensor use. You may also want to think twice if you don’t have metal mounting options and you’re unsure about adhesive placement.
Mini FAQ
How do the motion sensing modes differ?
All Day Sensing triggers on motion, while Night Sensing is intended to trigger motion only in dim environments.
How long do the lights stay on after motion stops?
They automatically turn off if no movement is detected for 20 seconds.
Can these be installed without drilling?
Yes. They use built-in magnets on metal surfaces, and for non-metal surfaces there’s an included adhesive metal plate.
What charging method is used?
Charging is via USB-C, with a full charge described as taking about 3 hours.
What colour temperature are they?
They’re listed as 4000K natural white.
