In high-temperature industrial environments such as steel mills, foundries, glass manufacturing plants, and chemical processing facilities, heat is more than just a challenging condition—it is the #1 cause of lighting system failure. With ambient temperatures frequently exceeding 70–80°C (158–176°F), standard LED fixtures weaken, fail, and even pose safety hazards.
Things like flickering, dimming, early burnout, melting, and electrical shorts are common when using light fixtures that aren’t built for high-temperature applications. This not only affects production but can also drive up maintenance costs and create safety issues.
Extreme heat doesn’t have to impact your lighting. When you use LED lights that are built to withstand extreme temperatures, you can have bright, safe, and cost-effective lighting. That’s why ACE has two industry leading high temperature solutions. Our CHB High Temperature Series and ELHB Series are engineered to perform in some of the most demanding environments.
This guide breaks down how heat destroys traditional lighting, what features matter most in extreme environments, and how ACE’s engineered solutions ensure long-term performance.
Most standard LED and HID fixtures are designed for ambient temperatures of 40–50°C. When placed in environments above 70°C, they face three inevitable failure mechanisms:
LED chips lose efficiency and dim rapidly
Drivers overheat and shut down
Capacitors dry out or leak
Solder points weaken and fail
At temperatures of 60–80°C, internal components age 5–10× faster, leading to complete breakdown.
Generic fixtures use lightweight or poorly designed heat sinks that trap heat instead of releasing it, creating a destructive “thermal loop” inside the fixture.
The result:
Higher internal temperatures
Accelerated LED decay
Driver burnout
Unstable performance
High heat causes:
Rubber seals to harden and crack
Plastic housings to deform
Gaskets to soften and lose sealing ability
This allows iron dust, steam, chemicals, and moisture to enter the fixture, leading to:
Corrosion
Short circuits
Optic discoloration
Electrical failure
To withstand extreme heat, lighting must be designed from the ground up for high-temperature resilience—not adapted from standard designs.
ACE’s high-temperature lighting strategy is built on three engineering pillars:
Heavy-duty aluminum heat sinks with large surface area dissipate heat rapidly, protecting LEDs and drivers even at 80°C continuous operation.
Fluoro-Elastomer FKM gaskets
Corrosion-resistant coatings
Tempered glass lenses
High-temperature LED drivers
These ensure stability under heat, chemicals, and dust.
With IP65–IP66 protection, ACE’s high-temperature fixtures block:
Dust
Molten splatter
Oil fumes
Steam
Chemicals
This prevents contamination and maintains optical performance long-term.
The CHB Series is ACE’s heavy-duty high-temperature solution engineered for harsh, open industrial spaces where temperatures reach up to 80°C continuously.
A precision-engineered anodized aluminum heat sink rapidly transfers heat away from the LED chips and drivers.
Dust-tight protection keeps iron dust, graphite, and corrosive particles out.
These maintain elasticity even under extreme heat—unlike standard silicone or rubber seals.
Up to 73,000 lumens at 220 LPW provide bright, uniform illumination while reducing energy usage by over 60%.
Steel mills
Foundries
Forging workshops
Rolling mills
Heavy manufacturing
For complex environments with frequent layout changes—chemical plants, heat treatment lines, cement plants—the ELHB Series offers premium heat resistance with modular flexibility.
High-performance aluminum alloy heat sink keeps components cool and stable.
Ideal for facilities with high-pressure washdowns or chemical exposure.
Replace LED modules or drivers independently—no need to replace the entire fixture.
Reduces maintenance costs by up to 70%.
Plug-and-play sensors
Dial-adjustable wattage
Field-adjustable settings
Multiple beam angles
This reduces SKUs by up to 80% and improves energy efficiency.
Chemical plants
Heat treatment lines
Pharmaceutical factories
Steam-heavy environments
Large industrial warehouses
Choosing the right fixture is only half the equation. Choosing the right manufacturer ensures long-term success.
Every high-temperature product is tested for:
80°C heat endurance
