Photocell Activates LED Only in Low Ambient Light

The slim light has a photocell inside that activates the LED when it is somewhat dark to conserve battery life. When installed the slim light should be installed in a space that is fairly dark. It does not have to be complete darkness as the light sensor will enable the light if the detected light level is low (with a light intensity below about 10 lux at the light).

It is perfect for lighting kitchen counters and cupboards. Perfect to light inside cabinets, closets and armoires.

Tips on Operation

For indoor use only. A kit is included for use as an under cabinet light. This kit includes a sticker that can be attached to the unit to limit the motion detection range and reduce activations from foot traffic.

Installation under a cabinet or shelf can be done by first installing the mounting plate with the provided screws or double sided tape. The double sided tape is strong enough for permanent installation or you can also use the provided screws. After your light is installed in its permanent location, the motion sensor will trigger the light as soon as movement is detected. The Mr. Beams Slim LED Light will automatically shut off when after a period of time of no motion.

To optimize battery life, set the auto shutoff to 20 seconds. The motion sensor should always be oriented so that the sensor is closest to the walkway / front of cabinet / front of shelf where motion is to be detected. The best mounting location for the unit is as far away from the walkway / front of cabinet / front of shelf as possible while still illuminating the target surface. If the light is activating by motion too often, reposition the light further away from traffic. Excessive activation by motion will result in faster battery drain.

Color Name: WhiteSize Name: 2-Pack Verified Purchase
I was tired of tapping my hardwired under-cabinet lights with wet or messy hands while cooking, baking, or preparing any kind of food over my counters. Even more annoying the under cabinet lights built with my kitchen have three settings. The first tap is very dim - I cant see anything so I have to tap the lights again for the bright setting, but if I accidentally tapped to fast they lights would go to off (setting #3). They were nice at first but the appeal quickly wore off because I was unhappy with the functionality. Plus I think they are halogen, not LED.

The options in the wireless under cabinet lighting arena are fairly limited. Most of the lights you have to tap, click, or wave your hands right under the light to again be disappointed with the light output. I tried a few including the hockey puck Dragon Light by Sylvania, They weren't for me so they were returned to Stop and Shop.

I have a few Mr Beams lights for the backyard so naturally I was curious as to how these would perform, WOW. I can see and I have light exactly when I need it without having to touch anything, make a mess, or shake hands with the invisible man under my cabinets. When you approach the counter or even the middle of your kitchen the lights will turn on after sensing your motion. I can walk up to the sink to wash my hands or do the dishes and I don't have to turn any lights on. I can use the cutting board and have enough light to prepare food. These lights are small but they pack a serious punch in the light department.

The other part I thoroughly enjoy are their sleek look. I had visitors over last night and they asked "Where did you get those!?!" - extra cool points for me. They have a nice wow factor.

Color Name: WhiteSize Name: 2-Pack Vine Customer Review of Free Product ( What's this? )
What a good idea. These lights work on batteries - 4 AA each. They can be mounted with screws (included) or double sided tape (also included). You can set them for a short time on by an internal switch and also by placing the sensor in front or back - how sensitive it is for motion. They are easy to install, with the exception of sliding the cover off and on, but it gets easier, each time it is done.

The obvious place to use them is under kitchen cabinets for more light. We have used one for a dark corner where the coffee maker is - a great help early in the morning; but there are so many other possibilities - under a bathroom cabinet over a sink might be one and then the place we used ours. We have a media cabinet where I literally have put a flashlight in order to see what the settings for recording programs and working with the various gizmos down there are. Well with this under the shelf... voila as soon as my hands go under to put in a DVD or try to set recording time there is light - wonderful!

I put one on under each cabinet on the sides of he sink area. Those areas were shaded from the light over the sink, and if you were standing there working beside the sink, your body shaded the light from the kitchen lights. Now even in the dark, when I approach the sink, two nice lights come on and flood the counter tops. I just ordered 2 more for the shop and humm,,,.

I used these for my Ikea Pax wardrobe and it is perfect. When I slide open the door, they come on and illuminate the contents; then I just slide the door shut and in 20 seconds they turn off. Motion sensing has worked flawlessly. Don't let the single LED fool you light output is extremely bright. I'm no engineer but let's just say not all LED's are the same and this is one of those big expensive ones; it puts out more light than a 9-LED flashlight that I have. Buy these lights.

Color Name: WhiteSize Name: 2-Pack Vine Customer Review of Free Product ( What's this? )
Originally I gave this item 4 stars, but both lights have stopped working after a few weeks.

It will start saying on for a long time, when it is supposed to only stay on about 20 or 30 seconds. And when it does go off, it will stay off for 2 or 3 seconds then come back on again for another long time. The result is that it is on most of the time and will use up your batteries.

P.S. Even the replacement products that were sent to me quit working. I DO NOT recommend this product. You will be sorry if you spend money on this product.

Color Name: WhiteSize Name: 2-Pack
I live in an area where we have pretty regular power outages in the winter time due to weather and so we've become accustomed to doing all kinds of things in the dark or by candlelight. I actually ordered these to go under my kitchen cabinets to shed some light on our cooking activities and for that they work AWESOME!
However I really wish these just had a simple switch to turn them off to save batteries when our power is on because every time we walk into the kitchen they turn on. We've had these less than three weeks and they are already going dim, it's a hassle to put batteries in them when the power goes out so I really with they had an on/off button on them for that. Make sure you keep batteries on hand if you're putting them in a spot where they'll be going on and off regularly, like a kitchen or hallway.

Color Name: WhiteSize Name: 2-Pack Vine Customer Review of Free Product ( What's this? )
PROS: These lights are BRIGHT and have a good spread to the beam. The motion sensor acts reliably, and installation is fairly simple.

CONS: Your only options are to have the light come on for 20 seconds or 60 seconds. So this is great for a dark area where you're going to do something quickly - like finding cleanser under a dark sink. Not so good if you have a longer task. Also, as others here have noted, battery life is surprisingly short for an LED product using so many batteries (4 AA). Don't be surprised if you need to change them in about two weeks.

Overall, very handy in the right spot if your task is a short one.
