In high-temperature industrial environments—such as steel mills, foundries, glass manufacturing plants, chemical processing facilities, and heat treatment workshops—productivity depends on far more than machinery and workflow design. One critical factor is often underestimated: lighting.
When it’s blistering hot, most lighting will struggle to keep up. Traditional light fixtures (whether LEDs, HID, or metal halide) will dim or flicker and age prematurely or fail short, requiring frequent maintenance. When lights don’t perform well in these conditions, operators experience visual fatigue and make more mistakes. Safety incidents, unplanned downtime and poor worker morale can quickly follow. Research and countless industrial projects have proven that poor lighting can cost these types of facilities 10–20% productivity.
That’s where high-temperature industrial lighting comes in. Engineered to perform reliably at continuous ambient temperatures of 80°C (176°F) and higher, high-temperature lights provide stable, high-quality lighting where most others fail. ACE’s CHB Series High Temperature LED High Bay Light and ELHB Series High Temperature LED Linear High Bay Light are perfect examples of lights that were designed with these demanding applications in mind.
Before examining solutions, it’s important to understand how inadequate lighting directly limits productivity in high-heat industrial settings.
Whether you are working in super-hot areas watching molten metals, performing detail-oriented assembly work, doing quality control inspections or monitoring equipment, your team needs to see what they are doing. Struggling to see details in dim, inconsistent or flickering light is eye-straining. Eye-strain means slower response times and more errors. Studies show that well-planned industrial lighting can decrease errors by 15–30% and task completion by as much as 12%.
Working in extreme heat is already dangerous. Adding poor lighting to the mix creates an even more hazardous work environment. Dark shadows hide rolling equipment or liquid spills. Glare causes loss of depth perception. When combined with bulky personal protective equipment, poor visibility can lead to accidents and dramatically decrease reaction times.
Traditional lighting burns out quickly in high heat areas, resulting in more frequent burnouts. Each time a bulb needs to be changed it usually requires shutting down part of your operation, raising lifts and following lockout/tagout safety protocols. We all know how costly downtime is in a steel mill or foundry. Even one hour of downtime can result in thousands, if not tens of thousands of dollars in lost production.
Spending multiple hours working in hot conditions is tough enough. But when your employees have to endure that in a dark, dimly lit work environment it can really take a toll on energy levels and mood. Bright, consistent lighting with no glare allows employees to work more comfortably and feel more alert which can have a positive effect on productivity and attendance.
To truly boost productivity in high-heat environments, industrial lighting must provide:
ACE’s CHB and ELHB series are engineered to meet all these requirements.
Engineered for: Steel mills, glass kilns, metal foundries, smelting plants, and other large, uniformly heated spaces.
Exceptional Visual Clarity
The CHB Series delivers up to 73,000 lumens with efficacy reaching 220 lm/W, flooding high-ceiling spaces with bright, uniform light. This eliminates blind spots and reduces inspection and assembly errors in demanding environments.
Stable Performance at Extreme Temperatures
Designed to operate continuously at 80°C (176°F), the CHB Series uses industrial-grade drivers, anodized aluminum housing, and FKM fluoroelastomer gaskets that resist cracking and heat aging. Light output remains stable—no flicker, no sudden dimming.
Minimal Maintenance, Maximum Uptime
Advanced heat dissipation and corrosion-resistant coatings extend fixture lifespan beyond 50,000 hours, up to 5× longer than generic LED high bays in high-heat applications. This dramatically reduces maintenance labor and unplanned shutdowns.
Rugged Safety Design
With an IP65 rating and optional tempered glass lens, the CHB Series resists dust, chemicals, and impact from debris or molten splatter—helping prevent fixture damage that can compromise safety.
Productivity Impact
Industrial users report double-digit reductions in defect rates and measurable improvements in task speed after upgrading to CHB lighting, driven by clearer visibility and fewer lighting-related disruptions.
Engineered for: Chemical plants, cement factories, heat treatment lines, warehouses near furnaces, and facilities with changing layouts.
Adaptive, Targeted Illumination
The ELHB Series features independent rotating LED modules and multiple beam angles (30° / 60° / 90°), allowing precise light placement. This is ideal for inspection points, processing lines, and equipment zones where shadows slow work.
Smart Comfort and Efficiency
Dial-type wattage and CCT adjustment enables fine-tuning of brightness and color temperature based on task requirements. Optional plug-and-play motion and daylight sensors further optimize energy use while maintaining visual comfort.
Rapid Maintenance with Modular Design
Unlike traditional fixtures, ELHB allows individual LED or power modules to be replaced in minutes—without removing the entire luminaire. This minimizes downtime and keeps production running.
Built for Harsh Conditions
An IP66-rated tempered glass front and smooth, dust-resistant backside protect against steam, oil, chemicals, and debris. The fixture maintains clarity and performance even in hot, contaminated environments.
Productivity Impact
Facilities using ELHB report faster inspections, smoother workflow adjustments, and output increases of 10–15%, thanks to lighting that adapts as production needs change.
Both the CHB and ELHB Series are designed with human performance in mind:
By reducing fatigue and improving perceived safety, these fixtures help sustain performance and reduce absenteeism.
