Question: how many hours lighting will 6 batteries last?  thanks much!
Document: This puts out as much light as an overcast day at midnight. Batteries last about 10 hours and fade into obscurity. Oh well...
Not as much light as I was hoping for.Easy to install, and replace batteries.Doesn't eat up batteries as fast as I thought it would.
These are very nice. They don't give off much light, but are sufficient for under the counter or back up lighting usage. They do need to be mounted with screws though, as the fixture is too heavy to stay put using the hook and loop fadteners.
These lights are cumbersome. They are easy to mount with the supplied Velcro but it does not stick for more than 24 hours. The lights are ok for overhead lighting where there is no ac power but for accent lighting it is not soft enough. I bought four of these so I will find some place to use them. I think they are ok but I was disappointed.
Very versatile.It is very well constructed and can operate on either 3 or 6 AAA batteries. Various mounting options are available. There is Velcro included with the light if you should choose that method or it can be attached to an included mounting plate that is screwed into the wall. All screws, etc. are included with the unit. I've subsequently purchased another to place in a rather dark kitchen cabinet.
This is a great little light, and relative to many lighting options you might entertain, it's relatively affordable. However, compared to modern LED options and prices, it's not the greatest in the world. It's not quite as bright as I expected. There's no real way to describe the lighting. It's also very &#34;spotted,&#34; so don't expect this to &#34;light&#34; an area.
I bought these to light closets that had no wired lighting. They work well for their intended use. I did try to use one as an under cabinet task light but it really didn't do much. The velcro mounting did not work for me so I had to mount them with the screws and bracket. they do not put out a ton of light but in a totally dark closet they are much better than nothing or having to hold a flashlight and try to locate what you were looking for.
I also like the two mounting options. You can &#34;stick it&#34; to the wall or screw it in. I opted to stick it since, again, this is a closet turn bookcase I don't want too many extra holes in my house. This is just what I needed.
I love these lights!! Great for closets and camping much much more.I have told my family and friends about your products! !
The sticking tape does not work very well. i had to screw the lightsin. Therefore i have to unscrew them to change the batteries.
