Question: Just installed mine 8 feet above ground but the sensor only activates within 4 feet. Is this normal?
Document: The unit is great. Love the hole guides on the top back of the unit. It has just the right amount of brightness when dim and the motion sensor works well. The brighter mode is just right, not blinding, but more than enough to find the keyhole.
This light is so great! Easy to install and I love that it is solar powered and motion sensor. I can put it outside my house so when I come home I have light and I'm not leaving my porch light on all day. Great product!
I am very impressed with the light! It is so easy to install and maintain and it looks very nice: both the fixture and the lightingThe motion sensor works really well. I love the idea of having a solar light for every day use. It's a great buy for the price.
I was pushing on the motion sensor that looks like a push button instead at first until I seen that.So now my lights work extremely well. They are bright (LED bright) which is different than an incandescent bulb but they create sufficient clarity at night to see where you're going.
I love every solar and this light didn't let me down. I have been looking for one and everything is twice the amount. With it being solar I can post them all around the property. very nice amount of light. The motion sensor works like a charm. Good customer service with fast shipping.Update:  We had a snow and then some rain and my light stopped working.
This is a great solar/security light that I have owned for a couple months now. The build is exceptionally solid and very respectable. The lighting is bright when the motion sensor is activated, but not harsh. When I first activated it I was a little worried because I wasn't sure if it was on or not. My experience is that when it's first clicked on the security lighting kicks in for the 30 second timer then it's good to go.
This light is fabulous. The brightness is gives is superb and worth the price.I use this on my patio and love the dimming feature, what a great idea!At first I couldn't get the thing to light up , after two days I wrote them and they answered within a few minutes with the solution. Great customer service besides a great product!
It's an awesome light . I have a pitch black backyard and I have things out there that I don't want growing legs and walking off.. It stays on dim and wen you get around 15 feet from it, it's like daylight.. I am very happy with the light and would recommend it to all.. Thank you very much.. I sleep better knowing my stuff is safe ..
I really like the smooth, stainless steel finish on this light. I was able to quickly and easily install this on my porch and i think it looks like it was professionally installed. The best part is that it only takes two screws to hook it up. There are nice guides on top that help with correctly positioning the screws. It seems to hold a good charge, and the light is nice and strong.
it is easy to install and very useful. I would like to thank the seller for this nice product which makes me feel much more convenient at the night time.
