So far it works just great. We'll see when the snow come. It works great right now. we love, the way it shows off the flag

So far I've had no problems with any weather. I've had rain, frozen rain and snow and it has had no effect on the performance of the light.

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.

It would be fine to keep it in a air tight bag, no reason to keep in cold. Probably should keep it out of light too.

A Zippo will light just fine in cold weather. Be sure to use Zippo lighter fluid.

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.

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.

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

Hi Mike I live in Eastern Canada and we get all kinds of nasty weather here ...I had my lights since the Spring ,and those temps shouldn't be a problem ..

I have been using this bulb out doors in zero degree weather in New England. I also use one indoors!

There is no warm or cold. I never heard of it. It just plain light with right spiral blubs. That's all. I swing it and pull forward to me for up reading, when done. I swing it and push backward. It was very cool.

Cold does not seem to affect performance, but our use is in Northern California and we don't get as much cold. In contrast to the compact fluorescent bulb (which is notably slow to warm up even when it is not that cold), the LED light seemed instant on and instant bright.

Theoretically yes it should be possible to use your 8.5 watt tecnolamp bulbs in a freezer .led light bulbs technically are not limited to cold temperature use like most compact fluorescents are the only issue is if the low voltage rectifier circuit in the base of the lamp it may not work well in sub freezing temperatures I have read some limited technical specs and customer reviews about certain styles types or brands of l.e.d. bulbs not lighting or flickering in cold temps below 32 degrees but I do think this rare especially considering there are industrial and commercial light fixture manufacturers that produce flourescent style light bars that replace the flourescent tubes with individual l.e.d. elements and are designed to go in commercial grocery freezers and the like like the dairy freezer in most commercial grocery stores.I can't say anything more than just try and see if it works. I haven't had my l.e.d. bulbs long enough to give you a definitive answer .

Being that cold is most likely going to affect the z-wave performance. No mention of operating temperatures in the package that I can find.

I have seen no mention of the color temp of the LEDs. I would describe them as cool to cold. To my 65 year old eyes, when lighting pages on bright whitepaper there is the slightest blue tint, but when lighting scores that have yellowed with age the light seems wash out the yellow and sharpen the notes. It makes both situations easier to read.

Antonino, We use our cameras inside, so do not know if they would work outside at that cold temp
