What Happens to a Standard High Bay at 85°C
In a standard high bay, the LED and driver share one sealed housing. At 85°C ambient, internal temperatures exceed 100°C. Capacitors degrade. The driver fails. Replacing a single fixture on a high ceiling costs more than the fixture itself.
Two design decisions make the HB81 different from a standard high bay.
Separate the Driver and LED Into Two Chambers
Each component gets its own housing with independent heat sinks. Neither pushes the other past its rated limit. A split-type driver structure is standard for high-temperature LED fixtures across the industry.
Driver Derates to Protect Itself
When the temperature crosses the safe threshold, the driver automatically reduces output to protect the internal electronics. The light continues operating at reduced brightness rather than shutting off.

Built to Last in the Heat
The Chimluxor™ HB81 Series High-Temperature LED High Bay is the answer for industrial facilities where standard fixtures fail from heat. Split-type driver architecture keeps the power supply thermally isolated from the LED array, enabling continuous operation at 85°C ambient. Compared to conventional high bays that require frequent replacement in hot environments, the HB81 delivers lower maintenance cost, fewer replacements, and longer service life.

Three Extra Steps for High-Temperature Reliability
The HB81 is built on the same die-casting and assembly line as our standard high bays. What differs: additional quality checks that verify high-temperature performance before shipping.
Controlled Thermal Interface Assembly
LED board and heat sink are bonded under a controlled process to ensure consistent thermal transfer. Poor contact at this interface is a leading cause of early LED failure in high-temperature service.
Waterproof Tested to IP65 Standard
The driver housing must stay sealed against dust and moisture as the aluminum body expands and contracts with temperature swings. Each fixture is waterproof tested before it enters burn-in.
Burn-In Plus Thermal Chamber Verification
Every HB81 unit completes burn-in testing. High-temperature performance is verified using in-house thermal test chambers. Spot-checked units undergo full temperature cycling to confirm design integrity across the rated range.
Designed for High-Heat Environments
Rated for continuous operation at 85°C ambient. Suitable for any industrial facility where standard LED high bays fail prematurely from heat.
Steel Mills
Hot rolling and blast furnace areas with sustained radiant heat at high mounting heights.
Foundries & Smelters
Sustained high ambient heat with airborne particulates common to metal casting environments.
Power Plants
Turbine halls and boiler areas where persistent heat causes premature failure in standard fixtures.
Electrolysis Plants
Ambient temperatures reaching 80°C during production cycles. HB81 units are currently in operation at a domestic electrolysis facility.
Glass Manufacturing
Furnace rooms and forming lines where ambient temperatures remain elevated throughout production.
Chemical Processing
Exothermic processes and enclosed reactor areas with elevated ambient temperatures.
Other High Bay Series
If your facility has zones with different operating conditions, these series may fit other areas of your site.
