High Temperature LED Lighting for Extreme Heat, up to 150°C, 302°F

Engineered for hot, punishing environments where ordinary LEDs fail. These high temperature LED flood and high bay fixtures run in steel mills, paper mills, glass plants, foundries, chemical processing, and power generation. Choose the right platform by ambient rating, 60 to 80°C for most hot bays, 100°C for extreme heat areas, 150°C with remote driver for ultra high heat near furnaces and kilns. All models are industrial grade with sealed housings, high efficacy packages, and rugged mounting options so you can keep lines running safely and efficiently.

When to Choose High Temperature LED Lighting

High heat breaks conventional lights, drivers overheat, optics degrade, and lumen output falls. In bays where air temperatures reach 60 to 80°C, select a dedicated high temp LED with proven thermal paths and heat sinking that protect LEDs and drivers. For severe environments around annealing, metal treatment, or glass, step to 100°C rated units with larger heat sinks and sealed electronics. Ultra hot zones near furnaces, kilns, and hot end processing require a remote driver architecture, the light engine stays at the heat source, the driver is mounted remotely in a cooler zone so electronics live longer and output stays stable. With the right ambient rating and optic, you will reduce maintenance, improve visibility, and protect crews in heavy industry. Voltage flexibility, IP66 and impact protection, and vibration ratings help these fixtures survive the real world of cranes, dust, steam, and heat.

Family of high-temperature LED fixtures—EDGE 60–80 °C, RT-IL 100 °C, RT-IL-150C remote-driver—for furnaces, kilns, foundries, and hot-process areas.

High Temperature Lighting FAQs

Do I need a remote driver in hot zones?

In the very hottest zones near furnaces, kilns or ovens, the LED driver should not sit in the same heat plume as the light head. In these cases choose a remote driver configuration. The EDGE high temperature LED flood and high bay with remote driver and the RT IL 150C ultra high temperature family move the driver to a cooler mounting point, protecting electronics and extending service life in 100 to 150 °C environments.

How hot can each family operate?

Our high temperature fixtures are grouped by their maximum rated ambient temperature so it is easier to match the product to your environment. EDGE Series High Temperature LED Flood and High Bay fixtures are designed for hot bays and yards where ambient temperatures are roughly 60 to 80 degrees C. RT HPH High Temperature Round High Bay is rated for up to 80 degrees C and is suited to high bay pendants in steel mills, heavy manufacturing and hangars. RT IL High Temperature LED Flood and High Bay is designed for severe heat process areas up to 100 degrees C, 212 degrees F. RT IL 150C Ultra High Temperature LED Flood and High Bay handles the hottest zones near furnaces and kilns up to 150 degrees C, 302 degrees F. This makes it easier to match each product family to the actual ambient temperature at your fixture location.

What optics should I choose for high heat lines?

Use narrow beams, 10 to 40 degrees, to cut through steam or dust and reach the floor. Use 60 to 120 degrees for general coverage, and elliptical optics for aisles or conveyor lines.

Can I order high voltage drivers?

Yes, families are offered in 347 to 480 V or 200 to 480 V options in addition to 100 to 277 V. This supports long runs and industrial distribution.

Are these fixtures waterproof?

Enclosures are IP66, sealed against dust and powerful water spray, suitable for wet industrial locations.

What maintenance rules apply for 150°C models?

Mount the external driver in a cooler area, route the factory cable, and keep air space around the heat sink. This preserves lumen maintenance and driver life.

Which high temperature model should I choose for my application?

Start with your ambient temperature and mounting style. For high bay ceilings up to about 80 degrees C with standard pendant or hook mounts, choose the RT HPH High Temperature Round High Bay, which delivers about 31,200 lumens at 240 watts for mills, heavy manufacturing bays and hangars. For modular flood and high bay layouts in 60 to 80 degree C environments, use the EDGE high temperature LED flood and high bay with an integral driver. For lines and platforms up to 100 degrees C, select either EDGE high temperature with a remote driver or the RT IL 100 degree C family. For ultra hot spots up to 150 degrees C, step up to RT IL 150C with a remote driver and follow the recommended spacing rules around the heat source. If you are unsure, measure the ambient temperature at the fixture location during full production then select the family whose rating is equal to or above that value.
