How do these lights work in very cold temps?

Yes. I live in Colorado and the temps here will get well below zero and the lights continue to work. The shorter days will mean that they may not last through the night but even on the shortest days here I still get at least 8 hours.

I purchased these lights for my mother who lives in Baltimore, MD. The temperature has gotten down into the teens over the last two winters that she used them. When I've visited her in January when it was around 30-40 degrees, they were working great. I didn't see any degradation in the light being emitted. I can't vouch for colder temps as you'd find in more northern states. Overall, she's been very happy with them.

I use them as porch lights where it gets down well below zero in the winter. They always come on (they're on a timer), so I expect they will be fine in the icebox. These are brighter than I expected them to be, so I'm quite happy with them.

These lights have held up excellently for me in my garage with temperatures dropping down to around zero.

LED bulbs work just fine outside, and are not impacted by cold like CFL bulbs are. I have several outside and they have suffered no ill effects.

I guess so. No matter how cold, they come on as fast as the cord is pulled and at full brightness.

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.

The LED Lights Are A Bright Light. Warm Or Cold I Do Not Know Because We Have 1 In Our Bathroom Pointing At The Ceiling Above A Painting That Is On One Wall. It Puts Out Enough Light To Use The Facilities At Night. There Is No Hint Of Any Blue Hue, And The Only Hue I Can See Is A Yellow/Greenish Around The LED Themselves. That Is Caused By The Thin Ring Of Plastic That Surrounds Each LED Itself. ( 13 LED's Total)

Sorry, I can't answer since I did not order my bulbs until sometime in mid April 2014. they have worked GREAT since then, but no really cold weather.

I'm also having the same issue with 2 888LM's keeping the lights on constantly. They didn't seem to do it when first installed but nowall the time. I'm wondering if they get more sensitive during colder temperatures.I've turned the motion detection off for now unfortunately.

I live in Minnesota, I had installed the l.e.d bulbs and about a week later I think the cold weather affected them. I returned them for credit back to my account. hopefully this helps you.

I live in Colorado. The lights have been subjected to rain and snow. No problems. Be advised, however, if the solar panel is covered with snow, light can't reach the solar panel so the lights will not go on at night. Keep the solar panel cleared of snow.

They are not bad. I have had some 13 watts bulbs come on faster.. but it is not like it takes a minute before you see bright light.I do not know on cold weather. I have not tried these outside. I usually leave my outside cfl on 24/7 in cold weather, because they die out more quickly if you turn them off and on all the time in the cold.

I don't know if they will work in the dead of winter. I still have mine turned on and so far it has been down to 19 F. They tell you not to leave the batteries in during real cold weather so when it get down a little more I will take the batteries out until early spring.

The lights turn on by pressing with your thumb on the back. I squeeze it between my thumb on the back (label side) and my index finger on the front side. The translucent plastic material is harder to compress when it's cold. Also, the pressure needed seems to vary from sample to sample (I have 3). The batteries are changed by peeling off the plastic dome from the label side, removing the inner unit and sliding the 2 batteries out the side.

I purchased two of these and use them to control outside lighting. The did well down to about 20 degrees, it doesn't get much colder here.
