I am thinking of moving to LED but wonder about the performance of LED lights and globes in extreme weather conditions, particularly when it gets cold. Can anyone help here?
LED lights have huge benefits on other types of lights and globe s- and this is true for cold weather as well.
One of the reasons is that LED lights do not emit a lot of heat so are much less affected by temperature fluctuations.
LED lights perform much better than other lights and have vastly longer lifespans.
Temperature fluctuations (particularly on outdoor lights) can damage lights, which can crack and break. LEDs do not have this issue as they can handle much higher changes between heat and cold.
Definitely recommend upgrading to LEDs. Your lights will last longer and they will handle heat and cold much better.
The other thing worth noting is that non-LED lights have to use a lot more energy the colder it gets, to illuminate with the same amount of light. However LEDs do not, so they are much more efficient.
LEDs are definitely the best option for extreme weather - both cold or hot.
The efficiency and lifespan of non LED lights drops off big time during cold spells and winter. You can easily tell that LEDs are more efficient by the fact that they are much cooler when touched.
I hate to be the bearer of bad news, but LEDs still degrade in hot weather.
The reason is that LEDs still produce latent heat and may require heat sinks to dissipate that heat. However in hot weather, the heat cannot be disspitated fast enough so if it gets hot enough, for long enough, the LED will fail.
I would agree that heat can damage LEDs - but LEDs are fantastic in the cold and the light of choice here.
LEDs are perfect for outdoor in cold weather, specially in industrial strength lights - which is why so many signs and security lights these days are LED.
The reason LED lights are so good in winter compared to the old fashioned incandescent lights is simple: incandescent lights emit lights by heating up filaments, but only a tiny amount (less than 10%) of the power used to heat up the filament is actually converted to light. The colder it is the less efficient these incandescent lights become.
So long as the LED light is well made, which means a good heat sink, it will last forever in both cold and hot environments.
LEDs don't depend on heat to run, so they can handle temperature fluctuations very well.
It's actually even BETTER than you think! LEDs actually increase their efficiency the colder it becomes.
