For lighting recycling plants with extreme heat, heat-resistant LED fixtures are required that function reliably at ambient temperatures well above 60°C. Standard LED lighting is not designed for this and fails prematurely due to overheating of the electronics. In this article, we answer the most frequently asked questions about industrial lighting in high-temperature recycling environments.
What temperatures occur in recycling plants?
In recycling facilities, ambient temperatures can vary greatly depending on the material and the process. Around shredders, smelting furnaces, pelletizing lines, and compacting equipment, temperatures regularly rise to 60°C to 80°C. During the processing of metal scrap or thermoplastics, local peak temperatures can even be higher. This makes LED lighting at high temperature to a serious technical challenge.
Besides heat, infrared radiation also plays a role in environments where hot material is processed. Luminaires positioned directly above or next to melting processes are exposed to radiant heat that places an additional burden on the housing and internal electronics. This makes choosing the right luminaire more complex than just looking at the air temperature.
Why doesn't standard LED lighting meet the requirements in recycling environments?
Standard LED luminaires are designed for ambient temperatures of up to approximately 25°C to 40°C. In recycling facilities with extreme heat, operating temperatures structurally exceed this range, causing the LED driver and chip to degrade faster. The consequence is premature light loss, a shorter lifespan, and unplanned downtime.
What adds to this is that recycling environments are also mechanically demanding. Dust, vibrations, moisture, and aggressive gases are a constant factor. A regular LED lamp or industrial fixture without the proper protection class simply cannot withstand this. The combination of heat and these additional loads makes standard lighting unsuitable for this type of environment.
What are the technical requirements for lighting in extreme heat?
Lighting that works reliably in high-temperature recycling facilities must meet a number of specific technical requirements. The most important ones are:
- High maximum ambient temperature (Tc): The luminaire must demonstrably operate at ambient temperatures of at least 60°C, preferably up to 80°C or higher.
- Protection against dust and moisture: a high IP rating (at least IP65 or higher) is necessary to keep out dust particles and cleaning water.
- Vibration resistant: Installations with shredders and compactors produce constant mechanical vibrations that quickly damage cheap fixtures.
- Rugged casing materials such as stainless steel or specially coated aluminium offer resistance to corrosion by chemical vapours.
- Efficient heat dissipation: A well-designed heatsink prevents the LED chip from overheating, even during prolonged use.
For environments where explosion hazards or extreme chemical exposure are also present, additional requirements apply in the field of explosion protection.
Which type of luminaire is most suitable for recycling plants?
For most recycling plants, high-temperature LED floodlights are the most suitable choice. These fixtures are specifically developed for environments with extreme heat and are equipped with thermally optimized housings that effectively dissipate heat, even during prolonged exposure to high ambient temperatures.
In areas where hot materials or melting processes are involved, lighting fixtures that can withstand infrared radiation are required. Models such as the Orca HT and Barracuda HT from DCbright are designed for this type of application and can operate at temperatures up to +120°C. For workstations on the floor or around machinery, non-glare work lights are a good addition, as they do not impair operators’ vision.

How does poor lighting affect safety and productivity in recycling?
Insufficient or unreliable lighting in a recycling facility directly increases the risk of accidents. Operators working with moving machinery, conveyor belts, and heavy materials need good visibility to recognize dangerous situations in time. Poor lighting leads to more errors, slower reaction times, and a higher risk of injury.
Productivity also suffers from poor lighting. When fixtures fail due to overheating, processes must be shut down for repairs. In a 24/7 operation, that means direct production losses. Moreover, replacing fixtures in hard-to-reach places, such as above shredder lines or in heat zones, takes a lot of time and manpower.
Good lighting in recycling environments is therefore not a minor detail, but a direct factor in safety, continuity, and operational costs.
What should you consider when choosing lighting for a recycling facility?
The right lighting choice starts with a good analysis of the environment. Not every zone in a recycling plant has the same requirements, so a one-size-fits-all approach does not work here. Pay attention to the following points during selection:
- Map the temperature zones: Which zones reach structurally high temperatures and which do not? This determines which type of luminaire is needed where.
- Determine the present risk factors: consider dust, moisture, chemical vapors, vibrations, and infrared radiation. Each of these factors places additional demands on the protection class and enclosure.
- Look at the total life cycle costs: A cheaper fixture that needs to be replaced annually is more expensive than a robust fixture with a long lifespan and low maintenance.
- Consider accessibility: Luminaires at great height or in hard-to-reach areas must last as long as possible without intervention. Choose luminaires with proven reliability in similar conditions.
- Request a lighting design: A professional lighting calculation provides insight into the required number of fixtures, the placement, and the expected illuminance per zone.
Practical example: Rockwool Croatia
The Rockwool plant in Zajci, Croatia, needed lighting that could withstand ambient temperatures above 110 °C and the infrared radiation released during the production process. Standard LED lighting, and even many heat-resistant versions, fail under those conditions. On top of that, the LED drivers were not allowed to exceed 50 °C, while outdoor temperatures in summer already approach 40 °C. JEL took care of the lighting design and engineering and supplied more than 50 Barracuda HT, more than 20 Snapper HT and more than 30 Linear HT luminaires. The driver positioning and cooling were designed and tested separately, away from the hot production zones. The installation delivers more than 100 lux on the shop floor.
A recycling plant with melting or incineration processes faces the same combination: a high ambient temperature, radiant heat from the process and electronics that are sensitive to it. A luminaire can be heat-resistant while the driver next to it still fails. The position of the driver is therefore just as much a design choice as the luminaire itself.
