TANSOOL+ 20cm Under-Cabinet Kitchen Lights (2-pack) with Motion Sensor, USB-C Rechargeable LED

The essentials

If you want tidy lighting under a cabinet without running cables, TANSOOL+’s 20cm under-cabinet lights are built around that exact idea. They’re rechargeable, wireless, and designed to be mounted quickly—so you can get useful illumination in places like a kitchen work area, a hallway, a wardrobe, or the stairs. On paper, they hit a practical sweet spot: adjust the brightness, choose how the sensor behaves (always on/off, or sensing day/night), and let the lights handle the moment someone walks past.

That said, they’re not trying to replace a ceiling solution. Think of them as task-and-navigation lighting for short distances and specific spots. If your goal is bright whole-room coverage, you may end up disappointed.

What stands out in everyday use

The biggest day-to-day win is the combination of motion sensing and rechargeable power. In motion sensor mode, the light automatically activates when it detects human movement within a claimed range of 3m (10ft) at a 120° angle, then switches off after 20 seconds with no movement. In real-life terms, that means you can avoid fumbling for a switch when you’re carrying something—particularly useful on stairs or when you’re moving around the house late.

There’s also a brightness system that’s genuinely easy to live with: a short press lets you cycle brightness levels from 10%, 25%, 50%, 75% up to 100%. Plus, the frosted cover is intended to provide glare-free, eye-friendly light while still keeping brightness at a usable level.

If you’re the kind of person who hates leaving lights on “just in case”, the modes are built for that. One mode can keep the lights on, another can keep them off, and the sensing modes aim to behave differently depending on whether it’s day or dim conditions.

Where you’ll notice the design choice most is installation. There are built-in magnets for instant mounting on any metal surface, and for non-metal surfaces you use an included adhesive metal plate. The light units can also be taken off anytime—handy when it’s time to recharge or if you ever need to reposition them.

Key takeaways on the sensor modes

This 2-pack comes with 4 adjustable modes, which is where the lights feel more flexible than many basic motion LEDs.

In “all day sensing”, they light up when they detect movement. In “night sensing”, they only respond when movement is detected in dim environments. On top of that, you get “always on” and “always off”.

One limitation to keep in mind: motion sensors are always a bit dependent on the environment—layout, height, and how the sensor “sees” movement will affect how smoothly they trigger. If the lights are installed in a corner with awkward angles, you might find they don’t activate exactly when you expect.

Battery life and charging: the practical bit

These are USB-C rechargeable lights with a built-in 1100mAh battery. The manufacturer claims a full charge takes 2 hours. Once charged, it’s rated for 4–5 hours in on mode, or 2–3 months in sensor mode (based on 10 activations per day).

Whether that matters depends on how you plan to use them. If you’re mainly using them as motion-triggered under-cabinet or corridor lighting, you’ll likely see the longer sensor-based runtime. If you intend to keep them on frequently at higher brightness, you may cycle through charges more often.

Also worth noting: the runtime figures are presented as estimates. So, if you’re charging frequently and using them more than 10 times a day, your actual battery life may shift.

Installation reality check

The installation approach is straightforward: magnets for metal surfaces, adhesive metal plate for non-metal surfaces, then click the lights in place. That means there’s minimal fuss and no wiring.

One small “watch-out” is surface compatibility. Magnets will only help on metal. For everything else, you’ll rely on the adhesive metal plate—so it’s worth making sure the wall/cabinet lining area is suitable for sticking and won’t be exposed to conditions that would undermine the adhesive over time.

On the plus side, you can remove the units to recharge or relocate. That’s a nice touch for anyone who likes to change the setup seasonally or who doesn’t want fixed installations.

Pros and where it may fall short

Strengths

• Adjustable brightness from 10% up to 100% with a simple short-press cycle.
• Motion sensing with a defined detection range and a 20-second auto-off.
• Day/night sensing modes that aim to behave differently in light vs dim conditions.
• Rechargeable USB-C battery, avoiding battery swaps and wiring.
• Flexible mounting: magnets on metal surfaces, or adhesive metal plate on non-metal surfaces.

What to be cautious about

• Best suited to localised task/navigation lighting, not full-room illumination.
• Motion sensing performance depends on where and how you mount them.
• Battery runtime depends on whether you use “on mode” often or mostly rely on sensor mode.

Who it suits (and who might skip it)

It makes sense if you’re trying to solve a specific “dark spot” problem—under kitchen cabinets, a wardrobe that’s hard to light up, a hallway where you want lights without switching, or stairs where motion activation can reduce risk. The rechargeable setup is also a good fit if you don’t want to plan for wiring routes.

You may want to skip it if you need very powerful, room-wide brightness, or if your installation surfaces don’t work well with magnets and adhesive mounting. If you’re expecting sensor lights that behave perfectly regardless of room layout, you might find they need a bit of positioning fine-tuning.

Is it worth it?

Worth considering if your priority is wireless, USB-C rechargeable under-cabinet or indoor motion lighting with adjustable brightness and multiple sensor modes. It’s a practical 2-pack for typical UK household use where you want light that comes on when needed and turns off when it’s not.

Skip it if you’re after strong, wide-area illumination, or if you can’t guarantee a suitable mounting surface. For most people looking for convenient under-cabinet or hallway/wardrobe lighting, it should cover the basics well—just remember it’s more “spotlight on areas” than “lighting the whole house”.

Mini FAQ

How do the brightness settings work?

You can cycle through multiple brightness levels (10%, 25%, 50%, 75% and up to 100%) using a short press.

Do they need batteries or charging?

They’re USB-C rechargeable with a built-in battery, so there’s no battery replacement involved.

What triggers the motion lights?

In motion sensor mode, they activate when human movement is detected within the stated range and angle, then turn off after 20 seconds without movement.

Can I use them without a metal surface?

Yes—on non-metal surfaces you use the included adhesive metal plate so the magnetic mounting can still work.

Are there different sensor modes?

Yes. You get always on, always off, plus two sensing options: all day sensing and night sensing.
