Sensor lights are nothing new, Clipsal cornered that market for light switches for two decades here in Australia. When Quntis offered to send a couple of their LED Human Body Sensing Light, I thought it would be interesting to test the human part.
First Impressions
The Quntis LED Human Body Sensing Light is a flattish LED light that is not dissimilar to plenty of competition from Temu, Aliexpress and the like.
It has a metal casing around the LED part which is 25cm long. The overall length of the unit is 30cm which includes the sensor module and light temperature control.
On the sensor end of the LED is a USB-C charging port and a physical button which is a toggle. There is also a touch button right next to the sensor that is depicted as a fingerprint.
The LED comes in a pack of two, and each light bar comes with two metal mounting clips backed with 3M tape so you can affix it somewhere. The magnets are on the LED side.
Quntis has also included two short USB-A to USB-C cables for charging.
In Use
When I was doing a little renovations before moving into my home a few years ago, one of the things that never crossed my mind was to put a light into the area where the wardrobes are.
To be fair, I wasn’t living here at the time and certainly wasn’t staying the night during the works, so I never caught onto the fact that I could do with some extra lights in that space.
By the time I figured I needed it, things were done and I didn’t feel like paying for an electrician to put one in. Especially when my light switches are mounted on the architraves so it will be painful to do and repaint it all when I only just finished that job.
It was just something I lived with, until Quntis mentioned their offering and I thought why not? It would be the perfect place to put it.
With the adhesive backed brackets, I just stuck the LED on the underside of my shelf in the wardrobe. No drilling required which is handy. Also for renters, no damage to anything that a landlord can ping you for.
Operation is simple. There are four modes to the single physical button on the side:
- one press to have the LED constantly on
- two presses to night sensor, will turn on when human presence is detected and ambient light is low
- three presses to all day sensor, will turn on when human presence is detected
- four presses turns the LED off
The LED will automatically turn off twenty seconds after it last detects human presence.
When the LED is on, the touch button next to the sensor – the fingerprint symbol, becomes active. Short presses will toggle the light temperature between 3000K, 4000K and 5000K. So depending if you like your light warmer or cooler, you have the option to set it.
Long pressing this touch button for three seconds will put you into stepless dimming (or brightening) mode. You can adjust the brightness from 10% to 100%
The all important question is, does the human body sensing part work?
Let’s be honest, it’s passive infrared (PIR) sensor. No AI, no special smarts added. The sensor has a range of between 3 to 5 meters and 120 degrees.
PIR sensors works on infrared light emitted by a warm object. It is superior to standard motion detection because it is not a simple motion detector. The change in infrared temperature puts the “human body” detection in.
I of course, had to put the human body claims to test. I stuck the sensor in a position during testing where only my cats would be detected and sure enough, the LED came on and stayed on for the duration when it could detect their presence. It then turned off 20 seconds after they left.
To be fair, Tapioca is probably half human with his level of stupidity and intelligence combined. It never ceases to amaze me for such a smart cat he can do the dumbest things. Just like a human (and very much loved).
When it comes to brightness, I have no complaints. I have the LED mounted under the shelf above where my clothes hang. It is about 190cm off the floor and it casts enough light for me to see what is in my bottom drawer just off the floor.
Battery Life
The LED comes with a 2200 mAh battery, which not all that long ago was enough to drive a premium mobile phone.
It takes about three hours to fully charge from empty with a claimed thirteen hours of continuous operation at 100% brightness. I gave this a test overnight, letting it run in a cupboard and it last a lot longer then the hours I sleep. Twelve hours in and it was definitely dimming but still going.
Quntis claims in motion sensor mode, it can last up to 50 days. Obviously that is highly dependent on the frequency of use but recharging once every five or six weeks is pretty convenient.
Gripes
Less of a gripe but more of a heads up. The LED has a 10mm thickness which makes it suitable in many places. However in order to offset the minimal thickness, the unit is 40mm wide which may be an issue.
Conclusions
The Quntis LED Human Body Sensing Light is certainly useful and handy for lighting spots where you don’t have anything to work with. My wardrobe area for example, in a cupboard, or even say, the door to your caravan or tent.
I particularly light that it has three colour temperature settings and also ability to change brightness between 10 and 100% to suit your space.
The Quntis LED Human Body Sensing Light has a RRP of $49.99 for a set of two and are available directly from Quntis and also from Amazon. I probably will get a couple more for myself soon.
DRN would like to thank Quntis for providing the review units.
