As Winter arrives and the days become shorter, it is a great time to enjoy a good vibe with LED Lamps in cold weather. LED light has revolutionized the light system by providing an energy-efficient solution that can brighten even the darkest nights. They are designed to be long-lasting, durable, and efficient, and they are the best choice for outdoor applications. These savvy bulbs work well enough during winters when most bulbs are affected by temperature drops; LED works well enough to cater to this problem. Check out below how.


The common issues arise when using traditional bulbs during foggy nights. These regular lights will only work slightly in cold temperatures due to less capacity and thermal power. Generally, the cooler the environment, the greater an LED light output. These sub-zero light bulbs perform actively in cold temperatures. In this guide, you will learn about the working of LED lamps in cold temperatures and whether they are affected.

1- Can I use an LED Light Winter Outside?

If you want to light up your outdoors during winter temperatures with the warmest LED light bulb, it's a good decision. However, some outdoor LED lights can be used in minimum temperatures ranging from -40 degrees Fahrenheit to 176 degrees Fahrenheit or -40 degrees Celcius to 80 degrees Celcius. With LED durability, you can look forward to brightening outdoor spaces in the coldest winters. But the question arises: at night, during the dewdrops, are LED lights waterproof?


1.1 Waterproof LED Lights

Some LED snow lights are fully waterproof, and some are water-resistant. When choosing the bulbs, look for around IP67 or higher ratings. Water-resistant light works well when it is hit with water from any angle unless submerged. As such, IP65 or IP67 lights can handle raindrops but cannot work when immersed in the pool. LED lights made for the pool are specially designed with IP68.

  • IP65: Water resistant
  • IP67: Water resistant plus
  • IP68: Waterproof

Waterproof lights from Dazuma can be submerged in water up to 3 meters.


1.3 How Long Do LED Lights Last?

The main benefit of LED cold weather lighting is its longer lifespan compared to traditional bulbs. The question is, how long can you expect outdoor LED lights to last? The Department of Energy reported that LED lights can last between 30,000 and 50,000 hours before maintenance. On the other hand, different factors can affect it. If you always keep the LED light on,  they might last less than expected. If you want your LED to work for an extended timeframe, keep its duration shorter than usual or when needed.

2- Do LED Lights Work in Low Temperatures


LED lighting systems are ideal for chilly situations (up to about 20 degrees). They go nicely with both indoor and outdoor fixtures. LED lights, unlike CFLs, can start up in temperatures as low as 20 degrees, making them ideal for Houston's commercial fronts and parking garages. Furthermore, LED lights are more resistant to solid temperature fluctuations because they do not have glass components. They are sturdy and ideal for outdoor events and activites.

2.2 Advantages of LEDs in Cold Temperature

We have read that LEDs function better in colder temperatures, especially when installed outside. Here are some benefits for you to better grasp.

I- Durability in Snow Temperature

LEDs are becoming a popular choice among homeowners for street lighting. They can withstand high temperatures and even thrive in warmer regions. Cold weather can disturb regular bulbs due to their excessive heat emission. This can cause the bulbs to explode, forcing you to change them in the cold. Fortunately, LEDs do not suffer from this issue. Their light output and efficacy improve as the temperature lowers, making them ideal for outdoor illumination.

II- Stronger Light

Parks are also converting their lighting system to LED illumination. This is because regular bulbs can burn brightly and may be affected by the cold throughout the winter. The bulb will have problems shining brightly, and the internal pressure will decrease if it gets too cold. However, LEDs do not produce heat and are not sensitive to it. Thus, intelligent bulbs operate differently.

III- No Warm-Up Time

Regular bulbs take a long time to reach their peak brightness in mild conditions. In the winter, this may take much longer. As the system begins to heat up, you may have insufficient lighting for several minutes. LED lights do not have this drawback because they are designed to survive extreme weather conditions. When you turn them on, they start operating to their full ability, which is especially useful during the gloomy winter months.

Iv- Consume Less Energy

One of the primary reasons so many homeowners are installing LED lighting these days is the high expense of operating lights. These lights consume less energy when in operation. As a result, an installation budget may go considerably higher, but it will allow you to keep them on for longer or operate a brighter facility.

V- Performance

LED lamps last longer because they use less electricity to create light. This saves you money and time by reducing the frequency of changing your bulbs. You will be sure that your gardens, cold storage freezers, garages, and other areas are adequately lit.

3- What kinds of LED Natures will be Affected by cold weather?

Did you notice? In December and January, your LED light bulbs function better. Winter's dark days and cold temperatures increase the intensity and longevity of LED lights. It's correct to state that the outside temperature, and hence the temperature at the light source, will boost light performance rather than merely cold weather. Overall, the lower the ambient temperature, the greater the light output of an LED.


In contrast, traditional light bulbs do not perform well in cold weather. Why? Because they are built that way. These bulbs use energy to heat the tungsten filament till it shines. It takes longer to heat up in the winter and frequently fails to operate in minus-zero temperatures.

3.1 LED Compare to Traditional Lamps in Cold Weather

Several factors distinguish both in each component. Read on to learn the exact variations between typical and LED bulb performance in cold temperatures.

I- Compare Light Effectiveness

LED lights turn on quickly; traditional bulbs take 60 seconds to work well. Traditional lights frequently take some time to cozy up and turn on in the cold. This may be uncomfortable, especially in business situations where people require light to work and operate safely. Unlike conventional lighting, LEDs thrive in cold weather and are as efficient in any other setting. Smart bulbs lead to more energy-efficient lighting, as LEDs consume significantly less energy, resulting in lower carbon emissions and higher electricity costs.


 LEDs utilize less electricity to create light and give excellent illumination for the price of power. In general, they provide brighter lighting than ordinary bulbs.

II-  Longevity

The second challenge is their longevity; new bulbs are designed to last longer, saving owners time and money. Otherwise, space or homeowners would spend a lot of money on replacements. Cold weather damages ordinary bulbs, especially when they are immediately exposed. This includes outdoor fixtures such as streetlights, ornamental, and security lighting. Their excessive heat allows them to explode when the temperature falls. LED lights avoid these issues since they do not generate heat and can endure temperature changes.


What is the lifetime of LEDs? They are known for a longer lifespan, often lasting 50,000 hours, which is almost 50 times longer than a conventional light. Moreover, it is 20-25 times longer than a halogen and 10 times longer than a CFL. Even if used for 12 hours daily, an LED bulb may last over 11 years.

III- Mercury Vapor Pressure

The main difficulty with conventional bulbs in cold temperatures is mercury. The mercury gas pressure decreases as the temperature drops. As a result, less mercury is available to start the light. Mercury emits insufficient UV energy for the phosphor to convert to visible light, resulting in decreased light output. Fluorescent lights operate by ionizing mercury vapor in the lumen tube. Specialized ballasts and lamps for fluorescent lighting are available, although they are more costly and require frequent replacement.


On the other side, LEDs do not contain mercury, making them a more durable option for outdoor lighting. It does not affect lifespans, and output remains unaltered. However, confirming with your distributor how low the temperature is rated is critical.

IV-  Lumen Depreciation

Lumen depreciation refers to the decline in light brightness over time. What is a lumen? In a nutshell, it is a light source's brightness ratio or output. Overall, a brighter light has a more excellent lumen rating. Studies have demonstrated that when installed in cold environments, LEDs degrade less and provide more lumens. Modern LEDs include unique features that avoid heat-related lumen depreciation. Watts quantifies the power consumption of fluorescent and incandescent lights, not their brightness. LED lights produce the same amount of light as halogen lamps, using only half the electricity. For example, a 6.5W LED emits the same light as a 50-watt incandescent lamp.

V- Low Maintenance

Replacing your old fixtures with LEDs eliminates the need to change your bulbs after every six months. This is particularly essential during the freezing winter, when climbing a ladder may be challenging. Accessing outside fittings can be difficult, if not dangerous, in some cases. Adding chilly temperatures or snow to the mix makes replacing blown-out bulbs a chore that may be easily ignored. Wouldn't you instead replace an LED T8 wrapped in plastic with a fluorescent T8 covered in plastic or glass, specifically on a cold day? Although the glass is not hazardous, it poses the same dangers as cleaning up glass.


While some ordinary bulbs have an exterior polycarbonate coating for shatter resistance, this is rare. Outfitting your outdoor area with LEDs before the snowy season eliminates the inconvenience of replacing a burned-out bulb, as conventional lights do.

So, LED Lights are Ideal for Cold Temperatures

The ramifications of LED efficiency in cold weather are critical to consider in residential, commercial, and outdoor spaces. LED lighting fixtures are a good use of energy, time, and other resources because of their durability and higher output efficiencies.


LED lights consume less energy than their predecessors, and in colder climates, they produce higher output. Of course, the scientific literature confirms this. According to a study published in the International Journal of Semiconductors, temperature significantly impacts the efficiency of LEDs. "It was stated that the light intensity depends on the usage of LED current and its environmental temperature. With the low-temperature intensity, it increases and carrier lifetime decreases."

The Bottom Line is this:

In cold weather, LED lights will outlast other kinds of illumination in intensity, lifespan, and utility. If you have decided to replace your old bulbs with LEDs, now is the perfect time. Hire a professional for the outside installation because it requires careful labor.
