Motion-Sensing Under-Cabinet LED Light, retail $12.99*
Manufactured by Mr. Beams™ (www.mrbeams.com)
Last updated 07-23-12

This is a motion-sensing undercabinet LED light, designed to be mounted underneath kitchen cabinets; this light automatically turns on when it senses somebody's hands near the countertop anywhere even reasonably close to the light and then automatically turns itself back off approx. 30 or 60 seconds later. It is completely self-contained (battery powered); no need to have costly hard-wiring done.

It is advertised to produce, "40 lumens of bright white LED light", however I am not equipped to verify this value -- you need a rather expen$ive (~$20,000.00) instrument called an integrating sphere to measure light in lumens, and I neither own nor have any type of access to one.
It is designed to illuminate 10 ft² {ten square feet} of counter space -- the beam is very wide and quite bright, and I have no doubts at all about this claim.

In fact, when I first installed batteries in it and then turned it over, my first thought was, "OWWWWW! MY EYES!! MY EYES!!!"
Yes, this little guy really is that bright!!!

The Motion-Sensing Under-Cabinet LED Light come in a sturdy UV-resistant ABS plastic body in two colors (off-white and brown); its high-powered SMD neutral white LED is protected by a thin, transparent, water-clear domed plastic lens, and it operates from four AA cells.

SIZE

Feed the Motion-Sensing Under-Cabinet LED Light four AA cells first, and THEN you can avoid breaking dishes when you try to take them off the counter at night.

After first removing the paper backing from one side of the furnished piece of double-sided foam tape, stick it to the bottom of the mounting bracket, peel off the paper on the other side of the tape, and firmly stick the mounting bracket to the underside of a cabinet or to the side or underside of a bookshelf that could use more light when you want to grab a book from it. Although its best if you orient the mounting bracket so that it's open end faces the rear wall (this enables the motion detector to sense you reaching into that area from farther away), you can affix it the other way if you wish as well.

If you're averse to the permanent nature of the tape, you may affix the mounting bracket to the surface of your choosing using the pair of included screws.

Slide the unit into the open-end of the mounting bracket, and "snap" it closed.

There are no switches to fuss with or forget; once batteries are loaded, operation of the Motion-Sensing Under-Cabinet LED Light is ***TOTALLY*** automatic.
To borrow a phrase from a popular infomercial, you just "set it and forget it" - it's easier than that though, as you don't have to actually "SET" anything. It comes on when motion is detected (and stays on for ~30 to ~60 seconds if motion is not detected thereafter), then automatically turns off.

To feed the hungry, hungry (or "not-so-hungry" as it is pretty miserly with its batteries!) Motion-Sensing Under-Cabinet LED Light, remove it from its mounting bracket by placing the thumbs of one hand in the circular depression where the LED is located and placing your fingers of the other hand on the sides of the bracket, and gently (or more firmly if necessary) pull the two halves apart longitudinally; e.g., don't attempt to pull the light off the bracket by pulling down on it because that won't work -- pull the halves apart from front to back!

Remove the four used AA cells from the battery compartment, and dispose of or recycle them as you see fit.

Insert four new AA cells into the compartment, orienting them so that their flat ends (-) negatives face the springs for them in each chamber.

Place the unit back into the mounting bracket, and slide it in gently (or a little more firmly if necessary) until it "snaps" back into place.

When the batteries are crapping out and need to be changed, the unit lets you know by simply refusing to turn itself off after 30 or 60 seconds of inactivity.

Current usage measures 0.09mA (quiescent) and 110.0mA (light on) on my DMM's 40mA (quiescent) and 400mA (light on) scales.

The Motion-Sensing Under-Cabinet LED Light was meant to be hung up somewhere and not {vulgar term for having had intercourse} with, not a flashlight meant to be thrashed, trashed, and abused. So I won't throw it against the wall, stomp on it, try to drown it in the {vulgar term for feces}bowl or the cistern, run over it, swing it against the concrete floor of a patio, use a medium- to heavy-weight ball peen hammer to bash it open in order to check it for candiosity, fire it from the cannoñata (I guess I've been watching the TV program "Viva Piñata" too much again

- candiosity is usually checked with a laser-type device on a platform with a large readout (located at Piñata Central), a handheld wand that Langston Lickatoad uses, or a pack-of-cards-sized instrument that Fergy Fudgehog uses; and the cannoñata is only used to shoot piñatas to piñata parties away from picturesque Piñata Island), send it to the Daystrom Institute for additional analysis, or inflict upon it punishments that a flashlight may have inflicted upon it.

So this section of the Motion-Sensing Under-Cabinet LED Light's web page may appear more bare than this section of the web page on a web page about a flashlight that was born to be a flashlight and nothing but a flashlight.

When triggered by motion, the Motion-Sensing Under-Cabinet LED Light turns on for ~30 or ~60 seconds (depending on how you set the "on-time" switch on its underside); then automatically extinguishes if no additional motion is detected -- otherwise it will stay on longer.

The beam is wide and exceptionally smooth; there are absolutely no artifacts (blotches, rings, or other nasties) whatsoever that I can detect!

Measures 21,900mcd on an Amprobe LM631A light meter.

This is a very wide-angle lamp, and if I've told you once, I've told you 31,054,500 times:
Wider viewing angles always, always, ALWAYS equal lower mcd values!!!

This video shows little more than a silly light turning on & off.

It shows the Mr. Beams™ Motion-Sensing Under-Cabinet LED Light being actuated by my placing my hand within close proximity to it (you can hear me say, "the light came on when I reach for the counter"), rearranging a couple of items on a shelf, and then the light automatically neutralising itself (turning off) ~30 seconds after motion is last detected, with me then saying, " and there, it automatically turns off."
