Question: How dark does it have to be for the motion sensor to work.  Can I mount under kitchen cabinets and have them turn on even with overhead light on?
Document: These are a great alternative to running wired lights under cabinets. The use as a motion detector only seems to work when the ambient light level is low, One can cover the light sensor to get the lights to come on when it is not dark. I, would love this if it had a switch to set the light to turn on without the light sensor involved.
I started with these under cabinets in a dark kitchen, then bought more for various closets and pantrys, where they really shine. They are perfect in closets - no need to turn a light on and off, if you are so lucky as to have one, and closing the door stops unwanted turn-ons and prolongs battery life. They are much- appreciated and I have to get some more. Easy to install, and doing so would be a nice gift to others.
So many manufacturers make portable LED lights but this is the first well made design unit with photo sensor and adjustable motion sensor. Sure you can install a $7 unit but you will need to turn the lights on and off. There's something that causes extreme satisfaction with automatic lights in closets/dark places (for me)... maybe I'm just lazy... Anyway you're not wasting money because the lights shut off automatically. The unit will only turn on when there is movement and when it's dark. Even the mounting brackets are adjustable so you can have that perfect angle.
These are awesome. My kitchen is very dark and there were areas of the counter that I wouldn't use because I couldn't SEE! At first I didn't think I would like the motion sensor, but now that I'm used to it I love it. Hands free lighting when you need it!
Love the motion sensor feature. We live off grid during the summer in a cabin on an island and it's great light before we have to turn on the generator (saving gas). The motion sensor is also wonderful for going to the bathroom in the middle of the night. We've tried other led lights but these work the best, are more powerful, and can adjust easily. We'll buy more.
I have installed these into and under my trailer cabinets,  they are so bright! I love that I was able to angle the sensor so that the light goes on when I open the door or for under the cabinet when I reach into the dark areas, but not when I rest a glass on the counter! very very bright!
Hard to install and the motion sensor feature on the lghts in intermittent at best. Sometimes they turn on, and sometimes they turn off, but they really don't work as they are supposed to.
I put these little giants to work in the under-cabinet messes of my kitchen, where there are goblins just waiting. It dispels the goblins and helps me find the exact tool I was looking for. The secret I will share is that they are not installed; I leave them loose so that if necessary I can pick up and use in the &#34;way back&#34;. Meanwhile, they turn on as soon as I open the door. Quite useful!
When there is no great solution these are good. I have closet where there is no light and no way to reasonably put a light fixture in it. I put tape over the light sensor on the lights and attached them to the door and door facing, when I open the door they turn on. They turn off with the timer when the door is closed. My impression is that they respond to infrared motion from the way they react. I occasionally have to swing my leg in front of one of the four lights to get it to turn on.
Good lighting in the dark. Lights are so sensitive they come on EVEN during the day. Thereby the batteries are used up so fast in less than 2 months. NOT battery efficient. I am changing out the batteries too soon, for my liking. I put them under the kitchen cabinets for lighting at night. The velcro didn't stick to cabinets and need to be re-fastened. These lights are too tedious. But good lighting.
Answer: yes
