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 LEDs are built for the most demanding conditions. LED High Temperature Lights are designed to operate in high ambient temperature environments from 150°F to 212°F (100°C). They are designed and engineered to withstand high ambient temperatures that most standard LED Fixtures would fail quickly in. Get Your Free High Temperature LED Lighting Plan

Frequently Asked Questions

We spoke to first time buyers and long-term customers to find out their most commonly asked questions when it comes to buying High Temperature lights. If you couldn’t find an answer to your question below, feel free to call us at (888) 423-3191 and a dedicated lighting expert will help you find the best light for your needs.

What are High Temperature LED Lights?

Most LED products fail quickly in ambient temperatures that are higher than what they are rated for. There is a simple explanation why. Most LED products are designed to 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. The sum of the heat they produce and the ambient heat of the surrounding environment must be below the stated upper operating temperature of the fixture. When its not, the expected life of the fixture is severely affected.

Engineers have developed high temperature LED fixtures understanding the inherent problems "standard" led fixture fail at in high temperatures. They develop larger heat sinks, add more LEDs that are driven far lower than capacity, and use larger drivers that are dialed down well below their rated capacity in order to lower the heat the components generate while in operation. So adding additional ambient heat does not raise their temperatures beyond their rated upper limit.

What are the ranges of operating temperatures offered?

We have 5 ranges of high temperature LED fixtures

max temperature up to 140F

max temperature up to 160F

max temperature up to 176F

max temperature up to 194F

max temperature up to 212F

Do you have proof these lights work in hot environments?

Yes. And not just scientific lab data tested by engineers. We have our lights installed in nuclear power plants on top of the reactors on the refueling floors where, in the months of summer, ambient temperatures can rise very high. We have many installations where are lights are installed in rooms with large induction and natural gas fired ovens. These lights have been installed in these environments for years are are still working perfectly.

What applications do these lights work for?

High temperature industrial applications include places such as:

Nuclear and Fossil Fuel Power Plants
Blast Furnaces
Chemical Plants
Steel Manufacturing
Hot Mills

Are these lights safe to operate in a nuclear power plant?

Yes. We have had these lights tested by a major USA utility and they passed all their testing to ensure they will not affect the operation of the nuclear power plant. The radiation within the building has not affected the operation of the lights. Other than supply extra safety cables to ensure the lights are always suspended, the lights are ready to hang where they are needed.

What about extreme cold temperatures?

While most of what we talk about is hot environments, the reverse is also true. These lights are designed to handle the extreme cold as well, where normal LED lights would fail. The same lights that are designed to handle 194F and 212F can also handle -85F.

How easy is it to install high temperature LED Fixtures?

That is where these lights are similar to standard LED Fixtures. It is no different. Different mounting options are available to mount these fixtures, such as eye hook, pendant, trunnion and wires. They also wire directly into junction boxes.

How powerful are high temperature lights?

We have models that can replace 250 Watt, 400 Watt and even 1000 Watt metal halide. Our most powerful models produce almost 60,000 lumens and have optic packages available for high ceiling applications.

Do you stock High Temperature Lights?

Yes, but not all models. Some of our lights are made to order, because it is important to configure these lights properly. 

What is the warranty period on these fixtures?

Under "normal" operating conditions, assuming the max temperature does not exceed the rated operating temperatures of the fixtures, they are warrantied for a full 5 years. They are all UL/ETL Listed and many are rebate eligible.

Can I get a lighting plan layout?

The short answer is yes. We offer free lighting plans for our commercial and industrial customers. Click on the button at the bottom of this page to request yours.

How many High Temperature Lights do I need?

That depends entirely on your building size and your lighting requirements. Are you adding new lights or replacing existing lights, 1 for 1. Fortunately, we can do a High Temperature lighting plan for you, modeling your indoor space inside lighting software, adding in different models until we meet your requirements. That way, when we ship you those lights, there are no surprises, just success. Want a free lighting plan? Click on the link below.
