Are LED Bulbs Good in Cold Weather?

If you buy something through a link in our posts, we may get a small share of the sale.

LEDs don’t need heat to work like most traditional light bulbs need heat to work. That’s why LEDs fare well outdoors during fall and winter. Traditional light bulbs normally heat up so it can power on and create light. 

Clearly, you can’t categorize LEDs as your traditional light bulbs. Which makes you wonder, are LED bulbs good in cold weather?

Are LED Bulbs Good in Cold Weather?

LEDs perform well even in very cold temperatures. As a matter of fact, the colder it gets, the more efficient your LED lights would work. However, you should keep in mind that there’s a threshold for all things. 

For LEDs, heat hinders them from working properly. LEDs also create heat yet not as much as incandescent or fluorescent bulbs. In fact, LEDs use heat sinks to dissipate heat away from the light.

Cold weather helps lessen the heat from LEDs. This makes LEDs more efficient in turning wattage into the light. Cold weather facilitates airflow around the bulb which helps remove heat from the heat sink. 

Why Do LEDs Perform Well in Cold Weather?

As stated above, heat limits how efficient your LED would work. This makes sense in how LEDs perform in cold weather. LEDs perform well in cold weather because:

  • Cold outdoor temperatures naturally aid in keeping your LEDs cool.
  • They don’t need heat to work, which means they work normally even in cold weather where heat is scarce.
  • LEDs mostly use plastic materials. Plastic can handle sudden temperature changes compared to traditional glass bulbs and they’re more durable. 

This makes LEDs unique to the traditional light bulb as they perform better in cold weather. 

What Are the Benefits of Using LEDs in Cold Weather?

You get a lot of benefits if you use LEDs for lighting in your ceilings especially in the winter season. Aside from them working better in cold temperatures, these are some of the additional things you get from using LEDs outdoors in cold weather

Longer Lifespan

When exposed to extreme weather, LEDs have a much longer lifespan compared to your traditional light bulbs. Traditional light bulbs emit too much heat and it doesn’t combine well with cold weather. Cold weather causes traditional light bulbs to burst if subjected to temperature drop. 

LEDs don’t have this type of problem. They don’t emit less heat and use materials that can easily withstand hot and cold temperatures. 

Low Maintenance

Using LEDs for your outdoor bulbs lessens your maintenance cost. You save a lot more in time and money as LEDs use less energy and can withstand cold weather much better than traditional light bulbs. 

With LEDs, you’re less likely to go outside and replace your light bulbs just because they don’t function in the cold weather.

High Efficiency

In cold weather, traditional light bulbs have to use more power to emit heat in order to produce ample light. LEDs can work in almost any harsh conditions.

LEDs don’t need to produce too much heat in order to create light. Temperature doesn’t affect too much how LEDs produce light which makes them your ideal option for outdoor lighting especially in cold weather.  

Brighter Lighting

LEDs don’t require a large amount of power in order to produce ample light. In fact, LEDs have the most lumen per watt compared to other traditional light bulbs. Traditional light bulbs also don’t fare well with cold weather that LED lighting tends to be a lot brighter compared to them. 

Will LED Lights Flicker in Cold Weather?

You don’t have to worry about LED lights flickering in cold weather. Cold weather doesn’t negatively affect the performance of your LED lights. You should have no problems installing them as your outdoor lighting to your home or property

However, you might encounter instances where your LED lights do flicker. You probably have a part of your LED’s internal component that’s broken or frozen. Most probably because the material is old, or cheap, or a rodent ate it away. 

Cheap LEDs tend to use cheaper components. Most likely they’re not temperature-resistant materials because these materials are usually expensive. You should invest in LED lights that have excellent build quality as it pays off in the long run with energy efficiency and longevity. 

How Do I Stop My LED Lights from Flickering?

You have to replace the broken or frozen component or you have to replace the whole LED light bulb. We recommend replacing the whole LED light as it’s much better and safer to do so.

If you see flickering LED lights, you should keep in mind that that’s not a good sign. Aside from the other reasons mentioned above, your LED might have a wattage problem or draw in more power than your LED driver can supply. 

Take the lights flickering as a sign of warning for a likely overload if you have multiple electronic devices installed in close proximity.

Related Questions

Before we go, it’s time to answer other questions we often receive related to this subject.

Are LED Lights Affected by Temperature?

In general, the cooler the temperature, the more your LED’s light output would have. Most LEDs have low light output when subjected to higher temperatures. Therefore, you would get the most out of your LED under cold temperatures than hot temperatures. 

This also explains why LEDs have heat sinks that help control the heat. If you subject your LEDs to prolonged heat, you shorten their lifespan a lot. 

What is the LED Operating Temperature Range?

In order to avoid putting your LEDs into too much heat or cold, you should know their temperature range. Operating temperatures among LEDs vary differently for bulbs. Most LED lights will work between -30°C and 60°C (-22°F and 140°F). 

They can easily work in most hot and cold places, so you can use them on a lot of different applications. If you want to get the best out of your LED lights efficiency and longevity, you should use them in places with an average of 25°C (77°F). 

That is according to Lightning Research Centre. This also means that if you go beyond 25°C, you would see a drop in your LED’s light output. 

Can You Use LED Bulbs in the Freezer?

LEDs thrive on cold temperatures which makes them great for freezers. In fact, most freezer uses LED lights for lighting now. 

LED also provides less amount of heat so your freezer won’t have problems maintaining the cool temperature inside. This also means your freezer won’t have to use too much energy to cool itself. You also save more energy costs running a freezer with LED lights. 


LED bulbs work better in cold weather than they do in hot weather. LED lights don’t work well with heat so having a cold environment makes them work better. You should try using LED lights especially if it’s cold in your area.
