I bought these lights to go around the inside of a homemade poker table. The lights came as expected. When I plugged the lights in the first time I thought they were very bright and great for what I need them for. However, the second time I plugged them in half of the lights are a different shade of white. The poker table looks great other than the messed up shades of lights...

I intended to use these to light the exterior stairs leading to my porch. They are mounted under the stairs (front of the steps are open) with the idea of the units recognizing motion coming towards them and under-lighting said stairs. It seems their ability to recognize motion in that axis (approaching directly, instead of side to side) is somewhat limited, as they don't light up until I am literally on the first step.

That said, these things are indeed very bright! I am not disappointed at all with the light output or the concept (only turning on when motion is sensed, and then only at night) as it conserves battery power.

I have since installed ambient lighting for the area in question that I can control with my phone, so I will find another use for these.

These little lights are very bright. I purchased two of them. The rotation portion is tight enough to hold and feels that it will remain that way for a long time. The clip has no issues with holding the light either. I plugged them into a iPhone 1.0 USB and an iPad 2.1 USB and there was no noticeable difference in light output. I am presently building a bed that I will put these on for nighttime reading and it will probably be a couple months before it is finished. So to test these lights, I have plugged them hanging upside down into a USB wall port (2.4amp) and will leave them on until the bed is done. I will try to keep this updated. Amazon should notify me if you ask questions and I'll do my best to answer them.

I was disappointed when I first got it it was what it's advertised but smaller than I imagined but when I opened it didn't realize it was USB I read the product description but didn't comprehend it totally I just thought it looked cool so I plugged it in turned on and wow it was bright it has three dim to bright and and it is perfect for my night stand or shelf above my head you can take it with you in the middle of the night but most off all I got for my nightstand to replace my big huge 60's lamp and this is very cool. I'm defenitly get a few more for my kids and I oh and my kids are begging for mine already and they can even play with make a fort and have lighting take it outside use light for working underneath you car when you need the perfect light to twist and get right where you need this thing is well worth it and the price in my opinion.
  After having it only for less than a month the charger in the lamp gave out and quit working I threw it away and bought something different. The charging plug in the lamp is very brittle and weak. I have only unplugged it a couple time and it broke. Not very satisfied with it after my first awesome review and a month of having it.

Had a section of the light go dim the second time I used it.  Since I needed the thing and it is crazy bright even with that section out i never bothered to return it.  When I get time I will pull it apart, probably a loose connection inside.  For the money I would still buy again if needed.

LEDs are very bright and sticky backing stays attached (for the two weeks I've had them) You need to have some wiring tools and knowledge because the LEDs have only a positive and negative wire on them. I wired them straight into my cigarette lighter with a switch on the dash (in case I get pulled over I can turn them off)

Overall if your a handy DIY kinda person these are cheap and very bright

Wasn't sure at first if these lights would work for my application but once I had them installed they worked great. I have just as much light as previously with the traditional fluorescents.

Hi I have these lights most people here don't realize  these are dual filament  bulbs if you ONLY use 1 power wire they will be kinda dim but put both power wires together and they are very bright

I put these lights under cabinents.  Once you figure out which side to plug in they work just great.  I thought I would use a few of the colors, but I usually just stick with the white.  You will have to invest in a roll of double side tape, because some of those do not stick well for long.  But no complaints besides that.

These actually might be too good. I had to put in a dimmer switch, because they were so bright. So far they are working out great, and I've had them for a few months now.

We replaced our garage lights with these. They are nice and bright and I hope they last a long time. One of them didn't work initially but with some fiddling with the socket it now works. Not sure if the fault is with the bulb or the socket.

I didn't get to hook it up yet and check its durability.  But I did turn it on right from the box and I was impressed it is pretty bright.  I will know more when I install and fully charge it.

I will admit I had my doubts about how bright these would be but they are quite bright.  I installed them to fill in areas in the garage that were dark and these more than do the job.  The light fixtures do seem a little flimsy and cheapish and were bent and tweaked but once installed they straighten up about 95%.  Even with that I'm thinking I may purchase another pair to replace the other two flourescent fixtures.  But, I would go with a 4000k for those as I believe having all 6500k temp lights in the garage would be almost too sterile.

I am very pleased with how bright the lights are But I am disappointed in 1 box I ordered new lights and they slipped in a used one in my order

We have a bunch of lights go out in our storage area at work. I thought that I would use a few of these to help illuminate the room while we were removing items.

These seemed a little more focused than I would like, but they are certainly bright. With multiple units, I was able to cover the whole area.

I first rated these a 1 because when i put a battery in one of the lights it got really hot and smelled like burning electronics.. The company contacted me and sent me a new set and both of those work just fine so it must have just been a bad individual light.

Happy with them now.
