Nice little light- doesn't come with batteries

Nice little camping light; variable amounts of light; convenient hanging clip. If it came with batteries, I would've given it 5 stars.

I thought when I ordered this that it was more of a desk light, but it is just a little clip-on light.  It can stand on it's own, which is what I wanted but I wanted a bigger desk light.  I can see that now in the picture, and I would have sent it back but I got it pretty cheap and decided to keep it.  It does have a padded clip-on and looks nice.  The metal neck is adjustable.  The base is 2 1/2X 1 1/2.  It stands about 6" tall.  It uses 3 AAA batteries, not included and the lights are LED.  It is ideal for travel and puts out a little flood light that is nice and bright.  It holds it's position.

I'm happy with the light. It's well-made and the strobe feature is easy to toggle on. But the package incorrectly states thatONE CR123A battery is included. This item is not in the package anywhere. I re-ordered this item a second time because I thought it was a mistake. But again, the battery was missing.

This motion-activated, battery-powered LED light strip is handy to have in places where there is no electrical outlet. The motion sensor response seems adequate and the light - on new batteries - is decently bright. The down-side to this type of unit will be the continual cost of batteries: the "motion-sensor" part of this light will ALWAYS be using battery power, even in minute amounts - how else would it be able to sense random motion? I've tried the light in two different scenarios: 1)  on a dimly-lit stair landing and 2)  in a rarely accessed, dark space (e.g., safe, cabinet, etc.). In the stairwell application (where one might set the light off 5 to 10 times a day/night) I found the light to last for about three weeks or so, until the lights get too dim to be of much use. In the rarely-accessed scenario, I found that the unit would last about 3 months or so before needing new [alkaline, in this case] batteries. It would be great if this unit was more energy-efficient. In the meantime, I highly recommend getting and using some quality, high-capacity rechargeable AAA batteries to help keep the lifetime usage costs down.

Update: I am more impressed with the combination of this light and the EBL AAA 1100mAh Rechargeable Batteries. These 1100mAh AAA batteries appear to be about twice as bright (as in "wow") as the standard warehouse alkaline AAA batteries, plus lithium batteries tend have the same output before they need to be recharged, while the alkaline batteries tend to have a steady loss of output before they die. Plus, these will probably save some bucks if they keep doing well after 100s of recharges.

This is a good little light for under 5$. Bought it for my father-in law as a gift for him to throw in his four-wheeler. He may not use it, but I thought it would work nice in case he needed to. My one complaint is that it was turned on when I opened the package and it had no other packaging other than the light.

The biggest problem with these lights is that the batteries are not rechargeable. Even though it lasts a surprisingly long time on one set of batteries, I still felt like I was using up way too many batteries. Today, there is really no reason to be using disposable batteries for bike lights.

The light itself (when the battery isn't dying) is powerful and has a nice selection of blinking options, and the rubber attachment band is super convenient when you need to be constantly taking your light on and off if you are locking your bike up on city streets and don't want the light to get stolen. However, the rubber attachment band eventually breaks.

Good light.  Runs on 3 AAA batteries.  It does have memory, so if you keep it on "Less Bright" mode like I do, then when you turn it off and then turn the light back on again it will remember that you were in this case on "Less Bright" mode.  Doesn't seem to last a heck of a long time before the batteries need to be charged again, but that could be the batteries I use.

On that note I may want to get some Terergy AAA batteries.  The Tenergy AA batteries are really good.

I like this light because it clips tight on my Amazon reader.  I wish is would have only one AAA battery, but I guess you can't have it all.  The low light works great for me for night reading because it does not light up the room.  Some may feel the low light is to dull or low, but It works for me and I have not had to replace the two batteries yet and I've had it over a couple of months.

Nice light. Works as expected. Only problem is there wasn't a battery for the remote. Luckily I had one lying around.

This is a nice small light for decorating, although it isn't on a timer.  That is why I gave it four stars.

When I ordered this light I didn't read about the kind of batteries it used so when I got it I had to order batteries and a charger too.  The batteries ran about $15 for 2 batteries and a charger.  The light worked nicely and was very bright (not sure if it's 1000 lums but it's bright).  The only complaint is the batteries go into the light in what would seem backwards.  The plus side went in first toward the spring and led, while the negative side went towards the end cap.  This could have been the batteries I bought but I'm not sure.  Bottom line is that I have two batteries and one light so I will now order another one of the Ultrafire lights.

These are the batteries I ordered (TangsFire 18650 3600mah 3.7v Rechargeable Li-ion Battery)  There are cheaper ones out there but these rated high and work with this light, plus they included a charger that will charge two batteries at the same time even if the batteries are in different discharge states.

Good light, doesn't use much battery, motion sensor could be a bit better, but I would buy this again for sure (oh and quick delivery).

I have not needed to use it yet, but it seems like it puts out a decent amount of light for its size.  It is quite small and I will be buying a larger one for emergencies.  Others have said that the battery cover is difficult to put back on - and it's true.  Even though there are two arrows to match up, which is helpful, it's still kind of tricky.  I am in NYC and which just went through Hurricaine Sandy, so I will be buying a bigger one.

I like this light a lot. Only requires a single AA battery and lasts quite a long time.

The only thing that happened with mine is the piece inside the focusing housing came loose and unscrewed. I used super glue on the threads to lock it into place. Hasn't been a problem since.

Easy to install the batteries, nice light, seems sturdy, should last a long time and provide a small powerful light.

Purchased 5 of these little lights, 2 came with the batteries flat. Otherwise a great product, it isn't too bright that it would hurt your eyes, but definitely handy to have around.
