This is a motion-activated ceiling light, designed to be mounted on the ceiling (of course!) -- it automatically comes on when it senses somebody entering the room. It is completely self-contained (battery powered); no need to have costly hard-wiring done.

It is also photoelectric - that is, it automatically turns itself off and will not trigger during the day, and turns itself on/arms itself (for the motion sensitive portion) at night.

The Motion Sensing Weatherproof Ceiling Light comes in a sturdy UV-resistant ABS plastic body; its SMD white LED is protected by a transparent, water-clear plastic window (or "lens" if you prefer, even though it does not focus, defocus, or otherwise modify the light in any manner), and it operates from four C cells. It is the same shape and approximately the same size as a household fire alarm.

Unlike other "cordless" ceiling lights, this one can also be used outdoors and in humid indoor environments like above the shower in the bathroom, thanks in large part to a rather beefy O-ring that helps keep the insides nice & dry.


SIZE



Feed the Motion Sensing Weatherproof Ceiling Light three C cells first (see directly below), and then you can confidentally cross that room at night.

If the ceiling or wall (high on the wall is preferable to lower on the wall) you intend to affix the Motion Sensing Weatherproof Ceiling Light to is wood, start by drilling "pilot" holes with a 1/8" drill bit, positioned exactly 2.85" (7.15cm) apart. You may use the ceiling plate itself as a template; simply position it where you want the Ceiling Light mounted, use a pencil to mark off right where you want the screw holes, and drill them. Once you have the holes drilled, place the ceiling plate up there so that the screw holes match up with the ones you just drilled, and drive the included screws into these holes. Tighten them firmly, but not so tight as to cause the ceiling plate to become cracked or even busted.

Please be certain that the word "TOP" embossed on this plate faces you -- do not mount the plate so that this embossing faces the wall.

If the area on the ceiling or wall that you're hanging the light from does not have a stud, you can safely assume that the ceiling or wall itself is made from drywall (gypsum board). In this case, drill the "pilot" holes with a 3/16" drill bit first, insert the included drywall anchors into the holes, then proceed as described above.


There are no switches to fuss with or forget; once batteries are loaded, operation of the Motion Sensing Weatherproof Ceiling 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 "arms" itself when it becomes dark, comes on when motion is detected, stays on for 30 seconds (advertised; actually measured at 75 seconds), then automatically turns off. And when it starts to get light, the unit will not "trigger" when motion is detected.



To feed the hungry, hungry Motion Sensing Weatherproof Ceiling Light, carefully unscrew it approximately 1/30th of a turn from its ceiling plate, bring it to a desk, table, bed, etc. and turn it upside-down.

Unscrew the screw with a medium or large standard screwdriver, or a coin like a quarter. Remove it, and set it aside.

Unscrew the battery cover approx. 1/30th of a turn, remove it, gently place it on the floor, and kick it down the stairs so that termites will think it's something yummy for their insect tummies, drag it to their nest, then find it unpalatable so they just squat over it and pee on it...O WAIT!!! YOU'LL NEED THAT!!! So just set it aside instead.

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

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

Place the back plate back on, insert & tighten that screw you removed earlier, place it back on the ceiling plate, and give it a little clockwise twist.
Aren't you glad you didn't kick that battery cover down the stairs with all those termites with full bladders now?



The Motion Sensing Weatherproof Ceiling 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 poo-poo}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 aka. Party Central), a handheld wand that Langston Lickatoad uses, or a pack-of-cards-sized instrument that Fergy Fudgehog uses; and the cannoñata (also located at Piñata Central aka. Party Central) 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 Weatherproof Ceiling 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 Weatherproof Ceiling Light turns on for exactly 75 seconds, measured on a clock with a second hand on it.

The LED color temperature is advertised as 3,500K (a warm white color); however I do not have access to an instrument for measuring color temperature so I cannot verify this exact color temperature firsthand.

I do not have a place to affix this light to (the rental house lease states that nothing can be inserted into walls {or ceilings} any larger than picture-hanging nails), so I cannot show you (with pictures) how it might be used like this.

This is a very wide-angle lamp, and if I've told you once, I've told you 2,458,770 times:
Wider viewing angles always, always, ALWAYS equal lower mcd values!!!

Photograph deliberately left uncropped to show beam edge.



Beam photograph on a wall at ~10 feet.
Product was intentionally aimed slightly to the left so that the beam perimeter is visible.

Those colored graphics toward the left are my "Viva Piñata" posters, and that clock on the right that looks like a gigantic wristwatch is my Infinity Optics Clock.

You may also be able to see two of my SpongeBob SquarePants plush (Squidward Tentacles and Patrick Star) and a Digimon plush (Greymon).



This photograph shows that the O-ring apears a bit too large in diameter; I don't know if this is just a fluke or if it is a fairly common occurance.

TEST NOTES:
Test units of the RF Remote Control Motion-Sensing Spotlight and Ceiling Light, were sent by D.L. of Mr. Beams™ on 03-08-10, and were received at 12:21pm PDT on 03-22-10.

Product was made in China.
A product's country of origin really does matter to some people, which is why I published it on this web page.




UPDATE: 00-00-00






PROS:
Has reasonable intensity considering that it is fully self-contained
Motion switch really does the job
Batteries it needs are extremely common and relatively inexpen$ive


CONS:
The O-ring (encountered during battery changing) can be a bit fiddly -- this is what nocked that last ½ star off
