They require more ambient light to shut completely off, but they are great in the dark.

I would love to  comment on the light but I haven't used them yet.  They are quite bright in a dark room.  I have one complaint , one of the lights didn't work so I replaced the batteries and that fixed the problem.

they aren't as bright as i would have liked, but i have no qualms.  they're really light the night, just not so much in the daylight.

They work great for the cost of them. I ordered the beige ones. While they are not the best at stopping all the light at midday, for night time they are absolutely perfect.

These are not very bright at all, but they're wonderful for Halloween!

So dark! They also insulate pretty well, for how thin they are. I'm typing this at 8am Sun has risen 2 hours ago and it's still pitch black in my room.

These are extremely handy for those dark, out of the way spaces like the back of a closet or under the stairs.  Comes on with any movement, shines brightly, goes off after a minute or so.

People really like these.  Not super bright, but they do look cool without having to worry about plugging them in anywhere.  Best for dark corners of the yard where you want to add some pizazz.  Only issue is that the settings seem to have a mind of their own.  I like to keep them on constant, but they tend to like to automatically turn on in flash mode, and not in any particular flash.  Sometimes they are in rapid strobe, sometimes in slow transition and sometimes just flashing.  It's a mystery as to what it will be each night!

The product came super fast. They're great for night time all over the house. Great for people afraid of the dark but don't want to admit it. Love them

Doesn't really see in the dark but I knew that before ordering. They are very nice and work well in lower light situations. Only drawback was the flimsy carrying case. NP since I order a harness for it and have a case on hand that works

I used these on my 6 foot fence in the back yard so I can see my dog. The light when in dim mode is pretty weak but once the motion sensor is activated the light is impressive.

It has been consistently gloomy here for the last couple of weeks and these lights are still lit up in the morning .

These are fun and work really well even in low light.  We hung them in the trees at our Lake house for evenings and there is a lot of shade so I wasn't sure if they would work.  Just enough light gets through to charge them and they stay lit for quite a while.

Great for running in the dark.
The brightness and the strobe effect - make drivers see you.

These are pretty bright with a yellow hue, only bad thing is that you need to be around little to no lighting areas to even notice these. Other than that, it helps in dark places to get out from.

I love the way they loo, especially in a dark room. I do with they were a bit brighter because the light doesn't travel all the way through the plastic.
