Have these LEDs been tested in cold climates? I live in North Dakota, and my garage often gets to -25 Degrees F. Once it hit -37 degrees.

I have installed LED bulbs in my refrigerator in place of the 40W incandescent. They work fine. In theory, the ambient temperature should not affect a LED from functioning, unlike CFLs that take a while to warm up so the mercury can vaporize. In fact, the power supply in the LED bulb should operate more efficiently and last longer the colder it is

Jamster,LED in fact is the best choice for cold environments. They will perform and last even longer in cold environment.Steve ecoBright

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.

I should have said that they are in the freezer section too. About 0 degrees F. Not close to -37, but at 0F there is no degradation of light output and no warm-up period

Jamster,I have yet to see a led bulb with minimum operating temp less than -22 F. There may be a handful under that but I wouldn't expect it. Only question is how the bulb will respond....will it not work properly during extreme cold or will it kill the bulb...I don't know. If I were you I would buy a cheap led bulb to test it out.

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

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.

The LED will actually perform better the colder it gets. But heat on the other hand can reduce the efficiency and lifespan or in some cases even burn out an LED lacking a proper heatsink.

I've had these bulbs since September of 2014 and they are bright. No problems from 80 degrees down to -20 so far. Haven't even flickered. I can't vouche for the life expectancy seeing as I've only had them for 6 months.

In the lights that I ordered, all of the LED's are daylight (5500). There is an orange frost that is inserted onto the front that brings the temperature to 3200. IDK if there are more than one version of these 600's though, because I ordered some 300's that I was expecting to be similar, but they have half 5500 and half 3200.

HiWe do not have these lights under cabinet, we have them flush mounted over the sink so they're sort of enclosed. They do get warm. I can't easily access the fixture except where the 'bulbs' are. That surface is about 100 degrees according to an infrared thermometer. Wood ignites at around 450 degrees these puck are nowhere near that. I did feel the cabinet floor above the puck that has been on for a couple hours. It's barely warm. We had Xenon puck lights in the same location previously. Those got WARM, the LED puck lights are much cooler. For under cabinet use we went with the LED tapes, those are barely warmer than ambient.

The threaded area is made of plastic so temperature is their main concern. LED's should be fine.

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 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.

We've had our Phillips LED light hanging out in Colorado weather for over a year. The light performs flawlessly in rain, ice and snow. Our son has had the same model in an exterior security light for a few years with no problems. I think the LED bulbs will perform for several more years.

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!

Yes, the temperature probably should be above about 50 degrees. Higher would be better. I installed mine when the outside temperature was about 80. They are real well stuck.

Yes! The great thing is that the LED bulbs is that they stay cold to the touch. I have them in all my fixtures.

Mine works great on my opener. Plenty of voltage for a lawn mower battery. I couldn't be happier. I have had it for about a year now. I can't say for sure on cold weather but I don't see where temps above 0 would matter much.

they spec it in degrees kelvin. compared to other leds I've bought, they are more yellow, natural sunlight. The dispersal seems fairly even over the 120 degree pattern.

Hi Scott. I don't know from experience yet, but I'm in the same boat as you. I live in Ohio & have this bulb in my unheated garage. I read at least one review somewhere that said low temperature is not a problem & basically I'm hoping that review was correct. Btw, I'm very happy with this bulb so far despite the high price. I considered putting in fluorescent lighting but don't need to now with how much light this puts out. Good luck! Jerry
