Will outdoor led flood lights survive in freezing temperatures?
2020-09-24

While manufacturing has changed in this time, the main reason then for LED failure was heating. The cooler you could keep the LED, the longer it would last. I do not think this has changed much since then. While very cold temperatures will shorten the lifespan of LEDs, temperatures encountered in outdoor winter operations would only be good for the LED. LEDs thrive in cold weather. I recently replaced flood lights around my home with LEDs, replacing compact florescent bulbs which are horrible in cold weather. The LED flood lights come on to full brightness instantly. There may be some issues with different manufactures current control circuits being affected by the cold weather, but the LED itself should work better when it is kept cold.


Does LED Lighting Work in Freezing Temperatures?

The USA is known for its sweltering summers, but we have been blessed with relatively mild winters. Although it doesnt happen too often, even USA can get hit with a major freeze, like the one that happened last week. When that low pressure systems comes in, you want to know that your business can handle the cold just as well as it can handle the heat. Over the years, we have gotten a lot of questions concerning the the effects that freezing temperatures have on the performance of several lighting systems, particularly LED lighting. We thought it would be helpful to answer those questions here!


How Do LED Lighting Systems Perform in Freezing Weather?

LED lighting systems are actually the preferred lighting option for cold environments (to around 20 degrees). The work well with both interior and exterior fixtures. Unlike CFLs, LED lights have no problem starting up in temperatures about 20 degrees, making them perfect for Houston business fronts and parking garages.

Also, because LED lights contain no glass components, they are more able to withstand extreme sudden temperature changes. They are durable and perfect for outdoor applications.


Do LED Lights Use More Energy in Freezing Temperatures?

Contrary to popular belief, light bulbs do not require more energy to operate in freezing temperatures; this includes LED lights.


In general, LED lights use less energy than other lighting systems. Most light bulbs lose most of their energy through heat energy: incandescent bulbs give off 90 percent of their energy as heat, while compact fluorescent bulbs waste 80 percent as heat. LED lights on the other hand, remain cool no matter what the temperature and emit light in a specific direction, thereby conserving energy throughout its lifespan. What out though! LED lights that are not Energy-Star certified are not as energy efficient as those who are certified.  While manufacturing has changed in this time, the main reason then for LED failure was heating.

5 WINTER MAINTENANCE TIPS FOR OUTDOOR LIGHTING


Keep your low-voltage landscape lights shining bright and well maintained all winter long with these five tips.

1) Keep Lenses Clean

Minerals deposits, dirt, and debris can dim or completely block the light from a fixture. Keeping your lenses clean is important if you want the best lighting effect. Particularly, low setting ground fixtures.


You can use a nonabrasive cloth and CLR type of cleaner to clean your lenses. It might take a bit of elbow grease to get it clean.


After a big snow storm, you may want to clear some of the snow from your fixtures. Halogen bulbs emit enough heat that may melt away most of the snow. LED bulbs produce less heat (this is why they are more energy efficient) and melt less snow.


2) Check for Exposed Wires

When the ground freezes and thaws, it can sometimes force wire(s) to work its way up to the surface. Exposed wires need to be inspected and reburied before the ground freezes. Exposed copper or damaged wire indicate repairs need to be made. We do not recommend doing this yourself. Check with the company that installed your system to see if they have a dedicated landscape lighting service department that can make the necessary repairs for you.

3) Adjust Fixtures

Over time, fixtures can move out of alignment or get damaged from landscaping, snow removal, or the wind (mostly downlights in trees). You can periodically walk through your property to re-align any crooked fixtures.


Take extra care when removing snow near fixtures. If a company removes your snow, let them know you have fixtures near where they plow (the drive and walkways are most common). You could purchase flags or poles from a local hardware store to indicate their location. The best way to maintain your landscape lighting system is to prevent accidental damages.


4) Check Bulbs

Extreme temperatures can shorten the life of a bulb.  We recommend you replace any bulbs that are out as soon as you can. Each bulb in a low-voltage system draws a small amount of voltage. As bulbs burn out, the good bulbs nearby receive more voltage, which can shorten their life. Landscape lighting systems tend to run longer every night since there is less daylight in the winter months.


We recommend utilizing an Annual Service Program. Look for one that includes having a service technician visit your property once a year to replace all of your halogen bulbs or check for faulty LED bulbs, clean lenses, reposition fixtures, complete a thorough performance check, and make any necessary adjustments or repairs.


5) Check for Common Moisture-Related Problems

Ice and snow can cause system outlet issues. More specifically, the melting can trip your GFCI outlet. If this happens, push the "reset" button on the outlet and make sure the cover gets closed. Please use caution when working with electricity and don't ever stick anything into the sockets. Sometimes an outlet may simply need reset and closed properly. If the cover is damaged, you'll want to get it replaced.


If the outlet looks damaged or will not reset, you may need to contact a licensed electrician.


Remember, anytime there is power loss, you'll need to reset the landscape lighting timer inside the transformer. Feel free to contact us if you have any questions or concerns about resetting timers or outlets. With all things electrical, please remember to use caution. Do not attempt to make any repairs if you are not familiar with the electrical systems. Safety is the number one priority.

Benefits of a Properly Maintained System:

A properly maintained outdoor lighting system makes your home safer, enhances its beauty at night, and aids in preventing potential intruders or vandals. Properly lit walkways can help avoid dangerous slips and falls due to ice and snow.  


Besides the winter, several of these tips can be completed at any time throughout the year. Please contact a professional with any major lighting or electrical issues.


Once again, we highly recommend an Annual Service Program. Our customers enjoy the peace of mind of knowing their family is safer because we check their lighting system every year and make sure it's performing its best.
