High Temperature LED Lights

From steel plants and foundries to pulp and paper mills, many industrial environments are home to high temperatures and scorching heat. And, while most lights would falter under such severe circumstances, high temperature fixtures are built for the most demanding conditions. LED High Temperature Light Fixture Lights are designed to operate in high ambient temperature environments from 150°F to 212°F (100°C).

Frequently Asked Questions

Purchasing High Temperature LED Lights is specific and unique to each customer. To help you with your decision, we spoke to our customers. We created a list (below) of their most asked questions. For more information, feel free to call us at (888) 423-3191.  A dedicated lighting expert will help you find the best light for your needs.


What Are High Temperature LED Lights?

Most LED products fail in temperatures that are higher than what they’re designed for. This means that the lumen output of LED lights in a hot environment will decrease at a much faster rate than it would at cooler temperatures. There is a simple explanation why. Most LED products work at the upper end of what the LED chips and drivers are capable of performing at. These components have an upper range of what is a safe operating temperature they need to be below.

Take the sum of the heat the lights produce and the ambient heat of the surrounding environment. This must be below the stated upper operating temperature of the fixture. When it is not, it reduces the expected life of the fixture and voids the warranty.

LED lights in high heat areas such as steel mills or foundries with operating temperatures of up to 205° F are tested. The main advantage is their ability to maintain optimal lumen output as temperatures climb. The light is also designed to provide long operating life with minimal fixture maintenance.

What Does High Temperature LED Lights Mean?

High Temperature LED Lights refers to lights capable of operating in hot environments. Our high heat resistant LED lights can operate in temperatures up to 212F.

Above these temperatures, these lights would experience a shortened lifespan. High temperature LEDs can operate in temperatures well above 150F. We also have fixtures that operate up to 212F.

Do You Have Proof These High Temperature LED Lights Work in Hot Environments?

We have scientific lab data tested by engineers. We also have our lights installed in nuclear power plants on top of the reactors on the refueling floors. In the months of summer, ambient temperatures are very high in these areas.

We have many installations with lights mounted near induction and natural gas furnaces. These lights have operated in these environments for years without issue.

What’s the difference between High Temperature LED Lights and LED Heat Resistant Lighting?

They are two ways of saying the same thing. Our high temperature lighting is also heat resistant lighting.

Do You Have a High Temperature LED Lights That Can Work Up to 100 Celsius (212 Fahrenheit)?

We do, our high heat resistant LED lights are capable of temperatures of 212F, or 100C. We also offer lights that can handle upper temperatures of 60C, 70C, 80C and 90C (140F – 212F).

What About Extreme Cold Temperatures?

While most of what we talk about is hot environments, the reverse is also true. These lights can handle the extreme cold as well, where normal LED lights would fail. The same lights that handle 194F and 212F can also operate in -85F. So in many respects, these are also Cold Temperature LED Lights.

What’s the Best Application for High Temperature LED Lights?

We have sold high heat LED lights to many industrial facilities and hot regions around the world. These include the deserts of California, Arizona, Las Vegas and the Middle East. We have many nuclear and fossil fuel power generation facilities that use our lights. Companies that use blast and induction furnaces in their manufacturing use our lights.


How Will the Light Perform If the Heat Goes Over the Rated Temperature?

If the heat goes above the rated temperature, then you can expect the light to have a shortened lifespan. Please note, the warranty is void in this case.

Do You Sell A High Temperature Rated Emergency Exit Sign?

We do sell explosion proof rated emergency exit signs. They’re rated to withstand temperatures of up to 185F.

What Is the Life Expectancy of High Temperature LED Lights and Fixtures?

We warranty the fixtures for 5 years. In normal operating conditions, you can expect that lifespan. The range really depends on

how high the temperature is
how many days a year that temperature exists
how many hours a day the lights are on

All are factors in determining the actual lifespan of these fixtures. In most cases, you can expect 10+ years out of a fixture.

What is the warranty period on these fixtures?

The warranty under “normal” operating conditions (not exceeding max temperature) are 5 years. They are all UL/ETL Listed and many are rebate eligible.

What is the optimal operating temperature of LED lights?

The optimal operating temperature is one that’s below the rated temperature of the lights. If a light’s rated for 140F, and you place it in a room that’s always 140F, you’re probably better with a light that’s rated at 150F or above.

Can Your High Temperature LED Lights Operate at the High Temperatures – 24 / 7?

They can. We would want to know about that environment in which they will operate. If max temperature is constant, then we need to supply a light capable of working in that environment.

Do You Have A Light That Can Withstand High Heat And Washed Down?

Yes, we have many high temperature lights that have an IP Rating of IP66. You can wash these fixtures or install them in a wet environment.

Are High Temperature Fixtures Dimmable?

Some of the fixtures can be, this is a special order. There is a problem with trying to dim a high temperature fixture. The switch or motion sensor used for the dimming also needs to high temp rated. We are not aware of any commercial lighting options available that support this.

How Were High Temperature Fixtures Tested to Confirm They Work at High Temperatures?

They place the lights in a very hot oven at the highest temperature ratings for long periods of time. The engineers calculate LED and driver decay based on the test. It’s the same way they determine the lifespan for LED lights. The only difference is the testing temperatures for these lights are much higher.

Is the Wire Attached Rated for High Temperature?

Everything we supply will meet the temperature rating its designed to operate in. This includes the wire whip.

Do C1D1 / C1D2 LED lights work in a hot environment?

They do, as long as the upper range of the temperature does not exceed 140F. The temperatures could rise above that, for short periods of time, and the lights will still be fine.


Do You Have High Temperature Fixtures for Industrial Applications?

Yes. Most, if not all, of these industrial led lighting fixtures are designed for high temperature industrial applications.

What Voltages Can Be Supported with a High Temperature Fixture?

We offer both 100-277V and 277-480V driver options on most high temperature fixtures.

Do you have any lights for high temperature areas on sale?

We do offer large quantity and contractor discounts, so reach out to us with any questions you have.

LED Lights in a Hot Environment


How Do I Install High Temperature LED Lights?

There is nothing special about the mounting. They are in many ways the same as a normal high bay light. For nuclear power customers, we offer safety cables to meet their standards.

Can I Get a Lighting Plan Layout?

The short answer is yes. We offer free lighting plans for our commercial and industrial customers.

We can do a high temperature lighting plan for you. We can model your indoor space inside lighting software. We can add in different models until we meet your requirements. That way, when we ship you those lights, there are no surprises.

How Many High Temperature Lights Do I Need?

That depends on your building size and your lighting requirements. Are you adding new lights or replacing existing lights, 1 for 1?

How Do High Temperature Fixtures Mount?

The same as a typical high bay or flood fixture. We offer

eye hooks
pendant and wire mounting
trunnion/yoke mount for ceiling/wall mount applications
