We get winter temps well below zero, does this light work in these conditions?

Have not had in winter months, it falls a little short on the dusk to dawn, but overall a good light.

temps don't mater, but it needs some sunlight to charge battery--BTW- It works great, I shine it from ground onto a 25 foot flag pole.

from wikipedia:Consumer-grade lithium-ion batteries should not be charged at temperatures below 0 °C (32 °F). Although a battery pack may appear to be charging normally, electroplating of metallic lithium can occur at the negative electrode during a subfreezing charge, and may not be removable even by repeated cycling. Most devices equipped with Li-ion batteries do not allow charging outside of 0-45 °C for safety reasons, except for mobile phones that may allow some degree of charging when they detect an emergency call in progress.

This has more to do with your batteies than the LED light. Alkaline batteries perform very poorly when they are below freezing. If you use rechargeable NiMH batteries then the light can operate down to -20C or even lower. I know this becasue I have this light powered byTenergy Centura rechargeable C cells in my (unheated) garage. During last winter the outdoor temperature can drop to 0F (-18C) at night, and the light still works.

Where I live it hasn't dropped below 28 degrees but the light works just fine -- mine is under a covered doorway so I'm not sure how it would work out in the elements. I bought Command strips based on other reviews and they worked well -- the Command strips are removable without leaving damage -- I've used them inside my home.

This will be my 1st winter so not sure. but so far it works great, brighter than what I expected.

I live in the Midwest and my lights are attached to an arbor on my patio. We had temperatures that reached 20 below zero this winter. My lights survived the temps and snow we had and are shining brightly as the day I put them out. You'll love them!

I have mine outdoors in Minnesota winter weather. The light tubes are sealed. I did put weatherproof protection on the power plug to keep it dry.

It's negative 20 degrees outside, here in Montana-- and it has been this cold for about a week. Both of my lights are doing great!

It seems to be about that. I use mine for my porch light and it has been working in temps as low as 40 below. I have a 60w equivalent also and it seem about right too. This has the soft white color so it has the incandescent color.

I found the light works well, however, the light spectrum was too cold (blue) for my tast.

Hi, last winter it got down to 10 below zero and it worked just fine no problems.

I live in Jefferson New Hampshire. About 50 Miles from the Canadian border. I installed one of these outside over my front door for light when I come home and have to find the key hole. It has been below 0 here and most of the winter below freezing. The light works fine out there exposed to the biter cold.

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.

I monitored the light during our recent very cold snap in Boston (~5 deg) and the light, mounted outside above our entrance, started and operated normally. The cold did not seem to have any effect on operation.

We purchased one of these lights last year for a vacation home in central wisconsin.When we went back to the house this year it was working just fine and i know they had some very cold weather this past winter.no battery problems at all.we havent changed them yet

Yes, it will flash slower as it begins to reach the target temperature and then finally stop flashing when it actually gets to temp. I'm using mine under a small water pond in a mini orchid greenhouse. I have it fairly well insulated, but it rarely stops flashing completely in the cold spell we've been having. In warm weather, it rarely turns on so it shows a solid light most of the time. Good luck with your application. The Fair Haired Finn

i live in Pittsburgh PA. the winters are long and cold. the lights held up well. heading into the second winter with no problems.

It is listed as an indoor light so you wouldn't want it exposed I don't think, but if you used an incandescent bulb before, like in an enclosed porch ceiling fixture, it would probably be ok. You don't have to worry about the bulb producing heat. Not sure how the cold May affect it.
