Question: is there an off and on button, my light stays on all the time until the batteries die
Document: Looks great. Was easy to install. Installed on stucko with no problem. Use quality batteries and they last a long time. But the light will get dimmer as the batteries go down.
It is very nice. Gives great light! I hope that it will last a long time. Very pleased. Easy to put up.
This is a handy light since it works off of batteries there is now wiring required. Just mount it on the wall and your good to go. Thinking about buying another one.
installed this on my back deck and it puts off just enough light. like how it turns off quickly once its been motion activated. really saves the batteries. Ive had this for several months and still havent changed the batteries.
Built very cheap, glass pieces do not sit flush. Looks good from about 20 feet away. Installed the batteries and the light would not turn off, read the instructions and mounted it in a dark place. Now it is just an ornament instead of being a functional light.
My house is over 120 years old, so it doesn't have some of the standard conveniences you'd expect like a light on the front porch. After investigating options to hard wire a new sconce on the front porch (which wasn't practical and very expensive), I decided to try this option. I like that it shuts off during the day time and it's sensitivity seems to be just right (e.g. no leaves in the wind activating it at all hours), but I do wish the light was brighter.
The LED lights run by batteries are bright when activated. The lamp was also very easy to install. I'm happy with this purchase.
Out of the 4 I purchased: 1 has a defective battery compartment that only works if you have the top of the fixture off. I have had 2 of the other lights come on and will not turn off until the batteries wore out. Very disappointed. They need an on/off switch at a minimum. On a good note. When they do work and come on they look nice for 30 seconds.
I would love this light if it were more powerful.
This was a gift but he like it. he was very pleased with light but it on his front porch.
