A food processing plant should never be treated as one uniform lighting environment.
Within the same facility, one room may be exposed to high-pressure hot-water washdowns, another may contain airborne flour or grain dust, and a third may operate below freezing. Ceiling height, humidity, sanitation intensity, chemical exposure, visual tasks, and maintenance access may change dramatically from one zone to the next.
Using the same fixture throughout the entire plant usually creates one of two problems:
Your typical warehouse high bay might work fine in a dry finished goods application but fall apart within weeks when installed above a seafood line. That IP69K linear fixture you have your eye on could be a necessity in a slaughtering application and cost prohibitive in a clean packaging warehouse. Wide-beam high bays can function just fine in a low production warehouse but cause glare and horrible uniformity when mounted much higher.
The correct strategy is to divide the plant into clearly defined operating zones and match each zone with a luminaire engineered for its actual conditions.
The most important factors include:
This guide explains how to evaluate the most common areas within a food processing facility and match them with the most appropriate ACE lighting solutions.
Food processing facilities typically contain a combination of wet, dry, cold, hot, dusty, hygienic, and corrosive environments.
These zones do not place equal demands on the lighting system.
For example:
A zone-based approach helps the facility achieve four objectives simultaneously:
Fixtures are selected according to their cleanability, housing geometry, and contamination risk.
Materials, seals, drivers, and lenses are matched to the actual environment.
Optics and output are selected according to mounting height, task, and production layout.
Facilities avoid both premature fixture failure and unnecessary over-specification.
Before reviewing individual products, divide the facility into functional and environmental zones.
A practical lighting survey should record the following information for every room.
Document:
Identify:
Record:
Measure:
Determine:
Once these conditions are mapped, each zone can be matched with an appropriate luminaire instead of relying on a single plant-wide fixture.
These are usually the most demanding lighting environments in the facility.
Fixtures may be exposed every day to:
In these areas, a small weakness in the fixture housing can become a contamination or electrical risk.
The luminaire should provide:
The A-HE01 Series is the strongest overall ACE option for severe wet and hygienic food-processing environments.
Key features include:
Its sealed, low-profile construction reduces bacterial harborage points and supports frequent washdown without exposing the internal components.
The A-HE01 combines several requirements that are often evaluated separately:
It is particularly appropriate where exposed food, water, chemicals, and frequent sanitation occur together.
When laying out A-HE01 fixtures, verify:
Use IP69K protection for areas exposed directly to sanitation jets. Do not assume an IP65 or IP66 fixture can survive close-range, high-pressure hot-water cleaning.
These zones combine the sanitation demands of wet processing with the optical challenges of high ceilings.
The lighting system must deliver broad, uniform coverage while remaining hygienic and resistant to water, chemicals, corrosion, and ammonia.
Look for:
The SHB Series is engineered for high-ceiling food-processing environments that require frequent high-pressure cleaning.
Key features include:
Traditional high bays often contain:
The SHB minimizes these features through a smooth, sealed structure that is easier to clean and less likely to accumulate:
The beam angle should be selected according to mounting height and fixture spacing.
Suitable for:
Suitable for:
Suitable for:
Do not use a standard warehouse UFO high bay in an intensive washdown hall simply because its lumen output is sufficient. Housing geometry, chemical resistance, and washdown protection are equally important.
These areas require light to be directed toward the work surface rather than simply downward toward the floor.
Employees may be inspecting:
At the same time, fixtures may be exposed to water spray, chemicals, and physical impact.
The luminaire should offer:
The VTP Series is designed for wet, chemically aggressive, low- and medium-height applications.
Key features include:
Suitable where priorities include:
Suitable where priorities include:
Suitable where priorities include:
Fixed linear fixtures may illuminate the floor but leave the conveyor surface or inspection plane underlit.
The VTP can be rotated toward:
This improves useful task illumination without increasing fixture wattage.
In inspection zones, excessive glare can cause:
Optional UGR below 19 can improve visual comfort where employees perform detailed line-side tasks.
Position linear fixtures to illuminate both the product and the employee’s viewing direction. High illuminance behind the worker does little to improve inspection accuracy.
These spaces may not require direct IP69K washdown resistance, but they still need:
Some areas may also experience heat from cooking, drying, or production equipment.
Look for:
The ELHB Series is a versatile choice for high-ceiling dry, semi-dry, and high-temperature production areas.
Key features include:
Food production halls often contain complex layouts with:
A fixed downward optic may create shadows or waste light above machinery.
The ELHB’s rotating modules can direct light toward:
When a driver or LED module fails, the affected component can be serviced without replacing the complete fixture.
This can reduce:
Use the ELHB where room geometry is complex or where different parts of the space require different beam directions. Its value comes from optical flexibility, not only high output.
Dry areas may appear less demanding than wet processing rooms, but fine particulate buildup creates its own hygiene and maintenance problems.
Dust can collect on:
This may:
In facilities where combustible dust may be present, the complete electrical and hazardous-location classification must also be evaluated by qualified professionals. A smooth housing alone does not make a fixture explosion-proof.
Look for:
The VHB Series is designed for dry and dusty food-processing environments.
Key features include:
A conventional finned high bay may collect dust rapidly.
The VHB’s smooth surface helps:
Where combustible flour, grain, sugar, starch, or powder dust may create a classified hazardous area, the lighting system must comply with the applicable explosion-protection requirements.
A standard IP65 high bay should not be treated as an explosion-proof fixture unless it is specifically certified for that classification.
Distinguish between an ordinary dusty area and a legally classified combustible-dust area. The fixture requirements may be completely different.
Cold environments create both thermal and moisture-related challenges.
Fixtures may experience:
Look for:
The NHB Series is a flexible high-bay solution for cold storage, warehouses, packaging areas, and mixed food-processing environments.
Key features include:
Cold rooms often have intermittent occupancy.
Lighting can operate at a reduced standby level and increase when:
This reduces both electrical consumption and the heat added to the refrigerated space.
The lighting design should also review:
Where cold storage also undergoes intensive washdown, the A-HE01 or SHB may be more appropriate depending on mounting height.
Do not choose cold-storage lighting based only on low-temperature startup. Confirm seal performance, condensation resistance, emergency-battery behavior, and control compatibility as well.
High ambient temperature can shorten fixture life dramatically.
The temperature at ceiling height may be substantially higher than the temperature experienced by workers below.
Look for:
The high-temperature version of the ELHB Series is designed for continuous operation at ambient temperatures up to 80°C.
Its relevant features include:
Excessive ambient temperature can cause:
A fixture may continue operating while suffering accelerated internal damage.
Use high-temperature ELHB fixtures only in areas where the elevated rating is needed. Cooler adjacent rooms may be served more economically with NHB, VHB, or standard ELHB configurations.
Measure ambient temperature at the fixture location during full production. Never rely only on the room thermostat or floor-level reading.
Some food plant areas do not fit neatly into either the harshest washdown category or the driest warehouse category.
These mixed zones need a flexible high-bay platform that can adapt to:
Look for:
The NHB is the most versatile general-purpose high-bay option in ACE’s food-processing portfolio.
It can be configured with:
The NHB is particularly appropriate for:
The NHB should not replace purpose-built IP69K fixtures in areas exposed directly to high-pressure sanitation.
For severe wet zones, use:
Use the NHB as a flexible generalist, not as a substitute for a washdown luminaire. Its main strengths are efficiency, optical choice, low glare, adjustability, and smart controls.

Although each zone requires a different fixture, several design principles apply throughout the plant.
Where hygiene matters, prioritize:
A practical approach is:
Where fixtures are installed above exposed food, the design should address breakage risk through:
Do not assume that glass is always prohibited or always acceptable. The decision should follow the plant’s food-safety policy and applicable regulations.
The lighting calculation should evaluate:
Review:
Measure the actual fixture environment during production rather than relying on room-level assumptions.
Useful applications include:
Avoid dimming below safe working levels in:
One of the most common food-plant lighting mistakes is using the same specification everywhere.
Examples include:
Potential consequences include:
Examples include:
Potential consequences include:
Each room should receive the level of protection, output, and durability it actually requires.
This produces a better balance between:
Fixture selection alone does not guarantee a successful lighting system.
A professional design should use accurate photometric files and real facility geometry.
ACE can provide DIALux and AGi32 simulations using model-specific IES data.
The design team should evaluate:
An empty-room simulation may look excellent while the completed production line performs poorly.
Machinery, pipes, conveyors, ducts, and racks can create:
The model should represent the actual production environment as closely as possible.
Food-processing plants frequently change.
Production lines may be:
A flexible lighting system can adapt more easily to these changes.
Where appropriate in exterior or support areas, field-adjustable products can also simplify long-term inventory.
