All Mr Beams LED lights install easily--no wiring, no electricians--so you can be assured of quality LED lighting anywhere.

Mr Beams offers simple installation with no wiring and no electrician needed.
Ceiling Light Features
Motion Activated and Auto Shut Off
The Ceiling Light instantly turns on when it detects motion, and can detect motion from as far as 20 feet away with a of field of motion detection optimized for ceiling mount application. The light turns off automatically after 30 seconds of no motion, conserving battery life.
Bright, Durable LED
The bright power LED provides 100 lumens of bright white light. A custom optical design is used to intensify the light by focusing it where it is needed. The LED never needs replacing--it's so efficient that you will get more than 3,200 activations on one set of batteries.
These are fantastic bright indoor and outdoor lights for closets, stairways, attics, basements, utility rooms, porches, sheds, garages or showers. The Ceiling Light is weatherproof for year-round illumination. Attach these ceiling lights anywhere in minutes without an electrician.
Tips on Operation
The motion sensor LED Ceiling Light has a photocell inside that activates the LED when it is somewhat dark to conserve battery life (aka, a “dusk-to-dawn” sensor). It does not have to be installed somewhere in complete darkness as the light sensor will enable the light if the detected light level is low (with a light intensity below about 3.5 lux at the light).
Key Features and Testing Your Light
Testing Your Light
Test the Ceiling Light any time by putting in fresh batteries and placing in a dark room. Leave the room to avoid activating it. The light should shut off after a minute or two and should turn on when you re-enter the room (the motion sensor may need time to settle after putting the batteries in.)

I solved this problem by modifying the unit's photocell which is located beneath the semi-transparent dome. Invert the unit on a soft cloth so as not to scratch the lens. Remove the "guts" of the unit by carefully releasing each of the four snap clips, adjacent to the batteries. This in effect removes the exterior case from the batteries and circuit board.
If you examine the circuit board, you will notice two components that sit below the milky dome. One is the circular motion detector and it has a small square window. The other adjacent component is the photocell which detects the ambient light level. It sits closer to the circuit board with a back and forth grid like element on its top.
This photocell must be completely isolated from receiving any light. Using black vinyl electrical tape, I cut small pieces of tape and placed them around the bottom of the photocell to cut off any light passing up through the circuit board and reaching the sensor. I even slid a small piece below the photocell, between its two leads just to be sure. Next I fashioned a small cylinder of tape just large enough to fit around the photocell. After closing off one end, I slid it over the photocell, kind of like a little hat and secured it into place.
Technically the photocell will now present only a small resistance to the circuit even in bright light. Assemble the unit taking care to position the milky dome back over the motion sensor and the photocell.
Mine now triggers on perfectly regardless of the ambient light in the bathroom when I stand in the bathtub to take a shower.
Installation is very easy. Be aware that this light takes 4 C cell batteries. Thankfully I had some on hand. The batteries make the unit too heavy for mounting tape...velcro might be okay. However I opted for the supplied screws and anchors. This makes me confident the light won't come crashing down on my head.
Now for the bad. Because the light uses a fish-eye type of lens to distribute the light it causes a strange prism effect. The light itself is white but at the edges the lens causes it to be yellow. I uploaded a picture to show what I'm talking about. It's not the end of the world but it's not something I expected.
Beyond this small hiccup the light works great. It comes on when the door is opened turning off about 30 seconds later. Given the choice between this and a wired light alternative I'll take this one all day. It only took 10 minutes to install. That's much nicer than cutting drywall, running wire, mounting a new light, patching, mudding, sanding and painting.
*** UPDATE ***
Soon after installing the light it seemed to be constantly on. A few test revealed it would come on as soon as it turned off. This was due to some older batteries I used. Replacing the batteries with new ones returned it to normal operation. It also made me realize just how bright the light actually is.Read more ›
It just stayed on all the time. Tried fresh batteries, still didnt work.
It was a great light while it lasted. Plenty bright enough to light up my
dark hallway, and the light would stay on long enough for me to navigate around.
There are no adjustments or switches at all on this model.
When you put the batteries in, it's on, when you take them out, it's off!!
My other motion sensor lights (different brand) at least have controls to switch
from allways on, or automatic sensor mode, or power off.
This unit has none of that, just bare bones and basic.
I am sure, after reading all the good reviews for this unit, that I just
got a lemmon (it happens sometimes).
I am giving this model a second chance, ordered a new one. I really like this
design, and the bracket is already attached to my ceiling.
So I would rather replace it and hope for the best, then remove the bracket and
have to fill in the holes and repaint.
Since these units appear to be fairly well made, I am sure the second one will be
a good one, but if not, I will buy a different model and hopefully it will cover up
the holes left by the Mr Beam unit.
UPDATE Feb, 2012:
I did buy another one and the exact same thing happened.
I have removed a star in this update due to 2 bad units.
