Question: How sensitive is the motion detection? Would it detect a chihuahua mounted outside on a single story home overlooking a normal sized backyard?
Document: I have had this light for about 2 month at this point. It is so bright, it blinds you. The motion sensor is adjustable, but even the factory setting is very sensitive and never fails.You have to mount it where it's protected, it's not rain/weatherproof.I had mine mounted outside my house and after the a good rain, it quit working. I put it on my porch, about to return it, but it dried outand has been working fine (UNDER the carport) for the last month.I would give it 5 stars if the whole unit was weatherproof.
We have three of these mounted in our large backyard - I never have to worry about power outages because they are solar and I don't worry about the light failing from running all night as they are motion activated. They are sensitive enough that I always have a light when I need it!
It did take a few days of use to get the adjustments set how I wanted them, but it works great now! I did have one morning where the temperature was close to zero and it would not come on all the way, but it was just that one time. The motion sensor is very sensitive as there are times when I take the dog out to potty and do not want it to come on and try to stay out of the detection area and it will still pick us up...good feature for security!
I admit I was skeptical at first, but it was a Gold Box deal and the price was good. I followed the directions to the letter, and am very happy with the results. The motion detection is very sensitive, more than I thought it would be. The adjustments are easy to make and work great. I highly recommend this product, and will be buying another soon!This light has been in operation since October 2012, and I couldn't be happier. It works great and the price is awesome!
This light is very easy to set up and seems sturdy. The light housing itself is metal instead of plastic which I prefer. I replaced included rechargeable batteries with higher rated  AA mHA ones. I charged the light inside for a couple of days and mounted to the outside deck. The motion sensor is sensitive and accurate. The light is small but illuminates better than expected. It lights approximately 200-300 square foot area very well. I don't know how it will handle in the long run. Our Wyoming winters can reek havoc on outdoor products, but the product is performing very well right now.
I installed the unit in about 10 min after letting it sit in sun for a couple days per the instructions to fully charge the batteries. The bracket for the solar panel could have used a bit more engineering as the mounting screws get blocked by the panel but with the right tools it is not that big of a deal. I installed this right on the railing of my deck as the big motion flood light I have mounted on the back of the house would not detect our new Pug. This comes on every time she leaves the deck and we can now see her and she can see the bunnies and give chase.
Had I written this review last summer, I would have given it a 5. But during the winter, it has not worked much of the time. Last summer, it completely lit the area by our covered, north facing back porch. Very bright light, motion sensor is very sensitive and lights with any movement within about 10 feet. It's great that it is solar powered, as there is no electrical to this area of our home. We may purchase another for the lake side of our home to light the way for those after dark arrivals from the water.
I mounted it well outside the stated 30' detection range. But warm engines/hot exhaust of vehicles going by still turn it on, even with lowered sensitivity. Annoying, but not a problem. Solar cell is big enough to handle all the false illuminations throughout the night.
Overall I am very pleased with these lights, I've purchased a total of four of them and they work very well. The intial light I installed primarily for my wife for when she arrives home in the dark. This lights illuminates the path to the outside electrical light switch. The light has worked very well, through two Maine winters so far. I would recomend this light when a hardwire motion light isnt practical to install
A great light I mounted one outside and one inside the garden shed very sensitive sensor lighting very bright LEDs enough to find tools and light a large swath of the driveway. Simple install and plenty of cord for most any need
Answer: yes
