I haven't taken a thermometer to it so I really don't know. The description for this reads as "Operates Temperature: -30°C to 83°C".

Depends of the application The price is low, consider your expectations, then have fun exploring some 18 century tech

We got to +15 here once and thought we were going to freeze to death! Anyway, I have not tried them that cold, I suspect they'll work just fine since most electronic things like that are good down to -40. We used to live in Edmonton, AB, it hit -47 (without windchill) once, we decided to move.

You would need a rather large amount of amps to reach that temperature. I would recommend getting these from a different source for the temperature you want. These may be cheap but they aren't very good quality.

They are rated for -40c if you look at there specifications , most LED fixture like the cold better than excessive heat.

Anthony, I'm a bit slow on installing these, I bought 8 fixtures last year and another 2 recently. T8 fixtures are supposed to work well in low temperatures (20 F) so I'm trusting the liturature I read and what I've heard from coworkers enought to buy 10 of these fixtures. Sorry I don't yet have first hand experience.

For me, probably not. I'd wear them down to maybe 15F, but even then my hands got cold.

Haven't had any issues using these for heating or cooling and I have 3 of them on the main level of my house. You should be fine using these on your vents in the winter unless they get really hot. If your vents get hot enough to melt plastic, you have other problems. :)

I am only using them for dry storage, but don't know why you couldn't use it for cold items.

i havent had a chance to install them yet it has been way too coldbut according to the information that come with them yes they are. Hope this helps

Not much, they barely get warm. You can easily handle them bare handed even when on full for quite awhile.

Hi Katie,I don't think you're supposed to. Depends on your climate. I have two outside but one on a porch and one way under the eves on the house. Haven't had any problems. But..not winter here yet. At 20 below zero F, that's going to be tough. 90% is keeping them dry and out of direct sunlight. Keep them powered all the time in the winter (that's the plan) because they will generate a little heat. If the wind's not too bad they might survive.

I have about a dozen of these that I have stored in my truck. I live in upstate NY where temps can drop well below freezing and into the single digits(both positive and negative) and have had them in there for about 3 years now. They freeze solid every winter and thaw every spring. None have popped.

This may work but I do not know how warm and what out side temps are. try some fiberglass mat insulation

I am using 6 of them and we aim to have them at -20 C when they go on my head and usually leave them for 20 mins (they are between -13 and 0 when I take them off to be returned to the dry ice).

It all depends on how warm you want it. If you just need to chase away the chill, it'll do fine. If you want it 80/90 degrees, it might not. I only use them to prevent freezing in garden tunnels, they just barely do it but that's all I need.

I have not used as a cooler. However I doubt it would work too well for that unless you made modifications. The plastic isn't super thick so you would be lacking in insulation. However, if you lined it with styrofoam first possibly it may keep things cold for a while. But do you really want to do all that for something that is going to provide minimal results at best. They make all kinds of nice coolers these days.

They will melt, but using in a soft side cooler was pretty good going to the island in 90 degree weather, the upside, the only "wet" you get inside your soft cooler is from condensation. If you start with your drinks already chilled it works even better. I love that it is reuseable and cuts down on leakage, also, you can wrap this entirely around a wine bottle.
