will this even charge in low light states in the winter like wi. we dont see the sun for a few days in a row and will the cold make the lights dim.?

Cold weather does not impact LED lighting function like it does on older CFL technologies. That said however, cold weather DOES impact battery charge capacity; not quite the same as occurs in 12V lead acid batteries, but the output can be diminished some by extreme cold. Adjusting the angle of the solar panel to capture more of the lower sun trajectory in the winter has worked for us here in Western Washington where cloudy skies are the winter rule rather than the exception. That said however we do hit a wall right about this time of year where there just isn't enough daylight hours for charging to happen. That is more about the current location than hours of sun. placement of the solar panel is key. Cold weather does not impact LED lighting function like it does on older CFL technologies.

with the new technologoy in these lamps they charge even when it is cloudy. don't know how the cold will effect them. i live in florida so i don't know.

I am not sure. I was not happy with it at all. The lights are not bright enough to see more that 2 feet in front of you. Sometimes it would not even come on with the highest setting.

It seems the lights aren't working on the evenings of overcast days. Really cold weather isn't a problem here on the Mississippi Gulf Coast.

I've never had any trouble charging irrespective of the light (or lack of); & the lights have maintained the same intensity.

We have had several cloudy/rainy days lately here in the deep south and I noticed this crazy light still coming on when I walk by, but like I said before, It comes on during the day time but seldom at night :(

Its the same in the Midwest, if the solar panel gets a full day or two of bright sun it has a chance to store energy. Read manufacturer instructions: "...Your solar panel needs to be placed outside in a sunny area and needs to face the southern sky. If it is in the shade it will still charge, but not as well as in the sun. If it is behind glass, it may not charge properly." Motion detector activates the light for a few minutes or so. Hopes this helps...

Allow it to charge with the switch off for a few good sunny days, then try it. If that does not work I would return for a refund. I noticed that ours these not work on nights when the weather had been overcast during the day.

I've had one mounted on a deck railing in Alaska fully exposed for a couple of years to light our dog's yard. I've never had any issues with weather, water, snow, or ice. For the price and convenience, this is a great little unit that produces a surprising amount of light. We just moved to a new house that is secluded and I'm going to purchase several more.

Jana, Thank you for your purchasing. The light also use the solar panel as a light sensor. if you put the panel indoor in daytime, the lux indoor still can make the panel works(very small current), and the circuit will think it still in day time and the led light is off. But if you cover the panel by sth. , the panel will no output, and the circuit will think it is at night and will let the light on. And since it is in winter, the sunshine is not so powerful to full charge the battery inside in many area. In summer, the working time will be longer.

I don't think cold weather can hurt this, as it's mostly just plastic (have to keep the socket dry, of course). As others have mentioned it's not very bright (makes a good desk lamp). Out of the 3 I bought, one went dim almost immediately. I kept it plugged in and used it behind an LCD monitor for wall backlighting, and it eventually brightened up to normal again. So if you get a dim one keep using it, it might recover.

Im not 100% sure but when I put it on my room floor by accident it charged from the light. It also works on really cloudy days even when there is hardly any light at all. Also, it's a little bit bigger than it looks like in the pics and stuff so make sure you have a could way to carry it.

Yes. Charges in the sunlight for a couple days under direct sunlight. You will see a red sensor light @night when motion is detected.

Not really. Sometimes I have to move/shake the charger pack (were the light that turns green is) so the light actually shows it's charging. Note that the manual says you should charge the battery periodically during the winter and allow it to be completely empty - it can damage it. Think of it like a car's battery - it charges when you run the car and if it goes completely empty you may need a new one

I really don't know but the manufacturer may be able to help. The other problem is the batteries are charged by sunlight and while I have never had a problem you might during the winter. I really like mine it has worked flawlessly since I installed it.

it doesn't matter; just leave it in the sun to charge it! IF your unit won't charge from the sun, then there are 2 possibilities:1. your circuit board is faulty and you need to replace the whole unit.2. you live in a place with latitude above 41 degrees or so, so solar power DOES NOT WORK in the winter because the sun is too weak.Seriously though, it uses a pair of AA Nickel-metal hydride (NiMH) batteries but THE UNIT IS SEALED so you can't really get to them.

Once the unit is fully charged it will work for days on that charge. It also depends on how much the unit is on. If the unit is triggered often the more it needs sunlight to re-charged. This light has worked great for me.

There is a key you insert into the on\off hole near the light. But it will need sunlight to charge.

The lights are not solar, so they dont need sun light to operate/charge. They can operate using a switch, but they wont come on during day light because it has a photo cell to detect the sun light.

I was hoping that this would help me save some money but it seemed to cost me the same and I was colder because of it. I stopped using it and my light bill isn't that much higher but I'm warmer now. Hope that helps.

I'm sure you can let the sun charge it but I charged mine overnight because it gave it a full charge to start. It won't charge at night or cloudy days so best to start with a full charge.

Eventually yes.The light alone pulls very little power. I haven't had a problem yet. However, I drive every day so it keeps the charged.

the Bulb is not weather resistant however I don't believe the cold will affect it is very dim though
