Industrial LED luminaires for factories, departments, warehouses and logistics areas: outputs up to 65,000 lumens, protection ratings up to IP66, components that work from −30 to +70 °C. Designed to last as long as the plant.
Request a lighting calculationThree things, and none of them is the quantity of light. The first is height: in a factory the luminaires sit at 6, 10, 15 metres, where nobody climbs to clean or replace them — every job at height means a lift, two people and a line stopped. The second is the environment: dust, oil mist, vapours, humidity, impacts, temperatures from the cold store to the foundry. The third is continuity: many departments run three shifts, and a luminaire burning 6,000 hours a year ages in two years as much as an office one in five.
That is why good industrial lighting is recognised by things that do not matter in offices: the IP and IK ratings, the thermal management of the LED, the optic chosen for the height, the replaceability of components without dismounting the luminaire. And, as everywhere, by the values EN 12464-1 sets for each task.
This is the starting page. From here you go into detail: LED technology for industrial environments (efficiency, lifetime, replacing discharge lamps), design department by department in manufacturing plants, lighting for warehouses and logistics areas, harsh environments, data centers, smart lighting for industry and the relamping of existing installations.
EN 12464-1 assigns each activity a maintained illuminance Ēm, a glare limit UGR and a minimum colour rendering. In industry the table is long because the activities are many: here are the most common ones, covering most factory floors. The rule is always the same — the finer the task, the more light it needs and the less glare is tolerated.
| Activity or department | Ēm (lux) | Max UGR | Min Ra |
|---|---|---|---|
| Rough assembly, heavy work | 200 | 25 | 80 |
| Medium assembly, welding | 300 | 25 | 80 |
| Medium machining (tolerances ≥ 0.1 mm) | 300 | 22 | 80 |
| Fine assembly, precision machining, grinding | 500 | 19–22 | 80 |
| Precision assembly, scribing, quality inspection | 750 | 19 | 80 |
| Continuously manned process plants | 300 | 25 | 80 |
| Dispatch, packing, handling | 300 | 25 | 60 |
| Warehouses and stores (100 lx if unmanned) | 100–200 | 25 | 60 |
| Internal traffic routes with vehicles | 150 | 25 | 40 |
Two things the table does not say. The illuminance is on the task area, which in a factory is not the floor but the working plane — the bench, the spindle, the conveyor — and must be calculated there, at its height. And the standard also sets a cylindrical illuminance (at least 50 lux at 1.2 m above floor where people move) because in a department you need to see faces and obstacles, not only the workpiece: it is the value that narrow-beam high-bay luminaires risk missing, and the reason the calculation must use real photometry.
The three data-sheet items that, in a factory, make the difference between an installation that lasts and one that gets replaced.
High-efficiency LEDs — above 150 lm/W in the latest ranges — with outputs from a few thousand up to 65,000 lumens per luminaire, colour rendering CRI ≥ 80 and colour tolerance SDCM 3. Colour temperatures from 4000 K, the most used in departments, to 5000–6500 K for inspection and precision benches.
The number that matters more than output is the junction temperature: the die-cast or extruded aluminium body is a heat sink, and its sizing decides whether the LED loses 10% of its output in 50,000 hours or 30% in 20,000. Versions for high ambient temperatures declare it explicitly.
The same wattage gives opposite results depending on the optic: wide beam for ceilings up to 6–7 metres with good uniformity, medium or narrow beam for 10–15 metres and beyond, where a wide beam would waste light on the high walls. PMMA or polycarbonate lenses, aluminium reflectors, tempered glass covers where chemical resistance and wash-downs are needed.
Die-cast or extruded painted aluminium bodies, or powder-coated steel sheet. Protection ratings from IP40 for clean departments to IP65–IP66 for dust and moisture, impact resistance up to IK10 where forklifts pass.
Compliance with EN 12464-1 for work places, EN 60598-1 for luminaires up to 1000 V, EN 60598-2-22 for emergency versions. CE marking, third-party ENEC certification and ATEX versions for zones with potentially explosive atmospheres. Electrical and electronic components qualified for operation from −30 to +70 °C.
DALI and Bluetooth versions with presence and daylight sensors: in a factory with rooflights and discontinuous shifts, controls are worth a further 30–40% — the detail is on the smart lighting for industry page.
Not catalogue features: the effects a plant manager sees on the accounts and on safety.
High-strength materials, high IP protection, electronics qualified for extreme temperature swings: the luminaire is designed for the environment it works in, not adapted afterwards. It is the difference between a declared service life and an achieved one.
Up to 70% less energy than fluorescent and discharge systems, on installations that burn 4,000–6,000 hours a year: in industry the LED payback is among the shortest of any sector, and relamping is often the most profitable energy investment available.
Optics and lenses designed for the real height avoid shadow zones between luminaire rows, abrupt contrasts between aisle and workstation, and glare for the forklift driver looking up. Correct uniformity and cylindrical illuminance are first of all a safety measure.
Long LED lifetime and luminaires designed to be opened and serviced in place: drivers and modules replaceable without dismounting the body, quick connectors, accessories for installation on existing structures. Fewer lift jobs, fewer stopped lines.
Weatherproof luminaires, linear fittings for high bays, industrial suspensions, track systems and the retrofit families for one-to-one replacement. Every range has its page with photometry, IES and Eulumdat files, IP/IK ratings and operating temperatures.
Other ranges for industrial environments: Beta 500, 3F Linda, 3F LEM, Beta 235, Beta i3F, 3F Cub, 3F Manta, Retrofit Beta A3F-i3F, Retrofit Beta 430, Retrofit 3F Cub, Retrofit 3F Linda.
Three plants where the light was designed on the real task, height and environment.
It must provide high luminous flux with an optic suited to the mounting height, uniformity on the working plane, resistance to environmental conditions — dust, moisture, impacts, temperature — and low energy consumption. 3F Filippi luminaires meet all these requirements, with efficacies above 150 lm/W, outputs up to 65,000 lumens and protection ratings up to IP66 and IK10.
Yes. The industrial range includes versions with very high IP and IK ratings and luminaires built with electrical and electronic components that withstand temperature swings between −30 °C and +70 °C: suitable for hot production departments, foundries and cold stores. For the most severe environments — frequent wash-downs, chemicals, explosive atmospheres — see the dedicated harsh-environments guide.
Certainly. 3F Filippi LED luminaires are compatible with DALI management systems, presence and daylight sensors and control via Bluetooth or network, to optimise consumption and improve safety. In a factory with rooflights and variable-occupancy departments, controls are worth a further 30–40% saving on top of LED: the figures are on the smart lighting for industry page.
By the optic, before the wattage. Up to 6–7 metres a wide beam gives good uniformity with medium-output luminaires; between 8 and 12 metres you need medium beams and 15,000–30,000 lumens; above 12–15 metres narrow beams and outputs up to 65,000 lumens, otherwise the light is lost on the high walls. The spacing between luminaires derives from the ratio to the height to guarantee the required uniformity: the lighting calculation sets it, not a generic rule.
It depends on the environment, not the sector. In a clean, dry department IP40 is enough; where there is fine dust or moisture you need IP65 or IP66; with pressure washing you go to IP66–IP69. For impacts, IK08 is the minimum where forklifts and goods pass, IK10 in areas with intense handling or within reach. A rating higher than necessary costs more and adds nothing: the choice is made zone by zone.
The reference is 4000 K, the neutral white that supports attention without fatigue. In quality-inspection departments, laboratories and precision work you go up to 5000 K, with CRI ≥ 90 where colours and finishes are assessed. Very cool temperatures (6500 K) make sense only in specific cases, and warm ones (3000 K) stay for offices and rest areas inside the plant.
With floor plan, heights and the use of each department our technical department returns the lighting calculation with illuminance, uniformity and UGR verification, the choice of optics for each height and an energy estimate. No obligation.
