Note #1:Size NOT as advertised/ contradicting dimensions given. I bought 2 black and 5 white of these for various purposes/ variety of situations, inside & outside. I would have given this 4-5 stars IF there wasn't EXTREMELY misleading dimension information on the size of these lights! (And, wish they were available in a brighter model for other uses). The FIRST paragraph line under "more product details" says: "Product Dimensions: 9 x 7 x 11 inches ; 4 ounces". I JUST DIRECTLY cut/ pasted this now. I was SO excited about this (Larger) size! However, these lights (black & white) are only 3 x 3 x 1.5 Inches. HUGE DIFF! Later-as in just now-I did scroll down & over (on my small laptop screen w/the slider bars) & in the BOTTOM RIGHT is a SECOND product dimention box, which gives the actual small size-totally contradicting the FIRST line. Why would anyone look for that once the very first line gives those large dimentions? Never occured to me. Note #2: Functional Quality: Great motion sensor! These motion sensors work every time, immediately-better than any I have on my hardwired outdoor lighting, etc...Lighting is a bit dim, which I prefer in some places, yet wish was brighter in others, but my needs are met. (Put one in a room w/ 2 entrances, 1 wall light & no switch for it @ 2nd entry. This lets me get into the room & get to either of the 2 main lights w/ ease). I had prevoiusly bought another plug-in motion sensor for a main lamp in the room (from Amazon), but the sensor was so poor that it took too long to pick up my movement & turn light on, and against advertising, could not keep monitoring my presence in the room, so I had to get 1 inch away & do the wavy dance every 15-20mins-uhg!!! so I switched to this & it works much better. NOT bright enough for a work light, but lets me see where they are. Note #3: Slight inaccurate color description: The "black" verson is more of a very dark grey, which is OK w/ me, but very different from what I expected. Depending on your intended use, this may or may not matter. Note #4: I was so impressed w/ the advertised pic showing the light used to illuminate an entire outdoor breaker box, that I want to do exact same thing (after a recent bad experience flipping back on a breaker in pitch black, pouring cold rain). This is an exact application which I need & hoped to use, BUT... there is more than a little cheating going on in the photo! After now having mounted 2 of these & being happy enough w/ the results, I can tell you that this particular photo has the light & bracket just dangling dangerously over the edge in order to get the LED's out far enough to light the panel (maybe even a little photoshop on the range/scope of broadcast light pattern & brightness, not sure but I suspect) & I have no idea what's actually holding it in place, if anything, because the pictured/ included mounting bracket is designed to be screwed (or otherwise secured) to the back of the wall, which sits back too far from any service panel to illuminate if mounted as per instructions/ intended manner. But, this application can be done w/ just a bit of ingenuity. I also bought some WATERPROOF "Command" brand large dual-sided damage-free removable tape strips, just in case (great price on Amazon Prime too), and I believe that I can first tape a small metal "L" bracket to the top front of the svc panel, then use one more adhesive strip on the back of the supplied plastic L bracket, put them back-to-back, and voila. It's set it up in a similar manner as in the photo. Then the LED's should (hopefully) stick out far enough to work & be reasonably safe & secure (for SoCal weather anyway). A number of other similar but heartier rig systems can be easily designed, I'm sure (2x4 scrap cut to size to screw bracket into, make a little housing/roof cover if in bad weather area, etc...) Just know it won't come out of the box w/ what you need to do what they advertise as pictured. Also of note, being fulfilled by Amazon, there's no easy way I can see to leave "seller feedback", informing them of the misleading info, but I'll keep trying. I just hope this information is helpful to others. These are not as big or bright as I'd like, but they are so reliable (trip easily) & multi-functional (stick anywhere in seconds) that I've found great uses for all of them. I'm even thinking of mounting 2 to the outside of both my van sliding doors & adding an RV type awning for beach/camping night use or just plain extra cool factor & security.
