The best tunnel light is not always the most powerful fixture. In Germany, a lower-wattage product with the correct optics, controls and maintenance strategy can outperform a brighter luminaire that looks better only on a datasheet.
Mining lighting creates a different trap. A robust IP-rated light may survive water and dust but still be unsuitable for an explosive underground atmosphere. Waterproof, tunnel-rated and mining-approved are not interchangeable descriptions.
This guide lists 10 manufacturers and specialist suppliers with verifiable tunnel, mining, hazardous-area or continuous underground-lighting products. It also distinguishes German manufacturing from German distribution and international OEM supply.

How the companies were selected
Every company needed official evidence in at least one relevant category:
- A dedicated tunnel-lighting application or product range;
- A named road, rail or metro tunnel project;
- Explosion-protected lighting explicitly suitable for mining;
- Continuous or temporary LED strip designed for demanding work routes;
- Tunnel control, guidance or retrofit systems supplied in Germany.
General lighting wholesalers and decorative LED-strip brands were excluded. Companies without a direct product, project or application page were not added merely to complete the number.
1. NORKA
NORKA is one of Germany’s clearest specialist choices for harsh-environment and tunnel lighting.
The company has a dedicated traffic and tunnel division under the VERNO name. Its range covers road and tunnel luminaires, robust linear products and lighting controls intended for demanding transport infrastructure.
NORKA also publishes direct project evidence. The Gildehof Tunnel in Essen, for example, uses several NORKA LED luminaire types for different lighting tasks. This combination of dedicated products, German project experience and extreme-environment engineering supports its position at the top of the list.
NORKA is better suited to fixed tunnel systems than flexible mining strip. Buyers should request the proposed luminaire schedule, photometric files and control architecture for the exact tunnel zones.
Best for: Road tunnels, transport infrastructure, renovation and intelligent control.
Company status: German manufacturer
2. SITECO
SITECO develops complete tunnel-lighting and modernization solutions rather than treating tunnels as an extension of ordinary street lighting.
Its official tunnel portfolio emphasizes high protection, glare control, homogeneous illumination and reduced maintenance. The company also provides retrofit approaches for replacing older tunnel systems while retaining usable mounting infrastructure.
Published reference material includes the Bindermichl Tunnel and Kaisermühlen Tunnel in Austria. These projects demonstrate experience with custom LED solutions, existing installation constraints and heavily used road tunnels.
SITECO is a strong candidate when lighting design, control, refurbishment and long-term operation must be handled as one project. It is not a mining-strip supplier.
Best for: Large road tunnels, LED conversion, lighting controls and lifecycle modernization.
Company status: German manufacturer
3. R. STAHL
R. STAHL is the most directly relevant German company in this list for explosion-protected mining lighting.
Its LED tubular luminaires include products identified for hazardous areas and mining applications. Published characteristics include high impact resistance, strong ingress protection and certifications covering gas, dust and mining environments on applicable models.
This distinction matters. A road-tunnel luminaire may be mechanically robust but still lack the explosion-protection classification required in a mine. R. STAHL should therefore be evaluated when hazardous-area compliance is the first requirement, not as a substitute for an ordinary low-cost utility light.
Buyers must verify the exact equipment group, zone or mining category, temperature class, ambient range and certificate number for the proposed model.
Best for: Hazardous mine areas, explosion-protected routes and harsh industrial sites.
Company status: German manufacturer
4. Xmart Lighting
Xmart Lighting is an international OEM manufacturer supplying continuous lighting systems from production bases in China and Vietnam.
Its Tunnel & Mining LED Strip is available in 24V, 36V and 48V configurations. Published features include IP67 protection, IK10 impact resistance, silicone extrusion and pre-terminated reels.
Xmart is relevant to German importers, distributors and contractors that need a configurable continuous system rather than a standard fixed luminaire. Wattage, colour temperature, reel length, connectors, cable exits, packaging and private-label requirements can be adapted for project orders.
The product category must be stated honestly. Standard industrial versions can suit non-classified service routes, conveyors, utility tunnels and construction passages, but they are not automatically ATEX-certified or approved for explosive mines. The exact delivered system must be matched to the site assessment.
Best for: OEM programmes, utility tunnels, conveyor routes and non-classified continuous lighting.
Company status: International manufacturer serving Germany
Product: View Xmart tunnel and mining LED strip
5. AEC ILLUMINAZIONE GmbH
AEC ILLUMINAZIONE GmbH supplies dedicated LED tunnel luminaires in the German market.
Its tunnel portfolio includes the T-LED family in several sizes and the MX PRO Tunnel range. The products are intended to address different tunnel zones through controlled, uniform and low-glare illumination.
AEC is especially relevant when the project requires conventional high-performance road-tunnel luminaires rather than linear guidance or flexible strip. Buyers should compare photometric distributions, surge protection, dimming protocols and corrosion resistance across the proposed models.
AEC’s manufacturing group originates in Italy, while the German GmbH provides a local commercial and project presence. It should therefore be described as a German-market specialist supplier, not mislabelled as a German-origin manufacturer.
Best for: Road-tunnel entrance, transition and interior lighting.
Company status: German subsidiary of an Italian lighting manufacturer
6. Broll Systemtechnik
Broll Systemtechnik offers specialist LED retrofit solutions for tunnel lighting.
Its published retrofit tunnel luminaire is designed to replace conventional installations while making use of existing equipment carriers or mounting positions where possible. Configurable colour temperature and lumen packages allow the replacement to be adapted to the original tunnel layout.
Retrofit engineering can be more valuable than buying the newest standalone fixture. Preserving compatible housings, brackets or cable infrastructure can shorten closures and reduce civil work, provided thermal, electrical and photometric requirements are recalculated.
Broll is a focused choice for operators modernizing an existing tunnel rather than sourcing flexible underground strip.
Best for: Tunnel renovations, retrofit projects and reduced installation disruption.
Company status: German specialist manufacturer and system supplier
7. Rhomberg Sersa Rail Group Germany
Rhomberg Sersa’s German operation supplies specialized lighting and guidance products for railway and metro tunnels.
Its portfolio includes individual tunnel luminaires and LED handrail systems. The handrail solution combines physical guidance with orientation lighting to support self-rescue and evacuation in railway tunnels.
This is a different function from primary road-tunnel illumination. A guidance system should be evaluated through visibility in smoke, mounting height, emergency power, spacing, impact resistance and integration with the tunnel safety concept.
Rhomberg Sersa is particularly relevant when lighting forms part of a wider rail-infrastructure or evacuation package.
Best for: Railway tunnels, metro systems, evacuation guidance and illuminated handrails.
Company status: German operation of an international rail-infrastructure group
8. GIFAS ELECTRIC GmbH
GIFAS ELECTRIC supplies robust electrical and lighting products for industrial, construction and transport applications.
Its FlexLED system is a portable, extendable LED strip mounted on a cable reel. Published features include IP65, IK10, a wide emission angle, lengths extendable to 100 metres and an emergency-battery option. The company also offers LED traffic-guidance products for tunnels and other transport environments.
This makes GIFAS relevant to temporary tunnel works, maintenance, emergency response and construction routes. It should not be confused with permanent primary highway-tunnel lighting or certified explosion-protected mine lighting.
Best for: Temporary tunnel lighting, maintenance routes, construction and visual guidance.
Company status: German specialist supplier
9. Lightronics GmbH
Lightronics GmbH offers robust LED products specifically presented for tunnels and underpasses.
Its German portfolio includes ANTEGO, A2, VENTEGO and other high-impact luminaires. Several products target vandal-prone environments such as underpasses, stations, parking structures and pedestrian tunnels. Published project evidence includes metro-station lighting in Berlin.
Lightronics is therefore most suitable where mechanical abuse, public access and ease of maintenance matter more than the high luminance needed at a fast road-tunnel entrance.
Best for: Pedestrian tunnels, underpasses, metro areas and vandal-resistant installations.
Company status: German-market luminaire supplier
10. Sagitar Verkehrstechnik
Sagitar Verkehrstechnik is a German tunnel and traffic-system supplier rather than only a luminaire seller.
Its official material covers LED tunnel lighting, adaptive lighting control and inductive LED guidance systems. Sagitar states that its guidance products have been used in more than 150 German road tunnels, with published examples including the A7 Schnelsen and Stellingen tunnels.
The company is relevant when the scope includes lane guidance, entrance lighting, monitoring or controls. Because some lighting products are supplied through technology partnerships, buyers should identify the legal manufacturer, warranty provider and certification holder for each component.
Best for: Road-tunnel guidance, adaptive controls and integrated traffic-lighting systems.
Company status: German specialist supplier and system integrator
The counterintuitive lesson from the German market
German tunnel projects often gain more from reducing installation and maintenance risk than from maximizing lumens per watt.
A product with slightly lower nominal efficacy may be the better choice if it:
- Fits the existing mounting system;
- Reduces lane closures during maintenance;
- Has replaceable drivers or modules;
- Delivers the required luminance with less glare;
- Integrates with the existing control protocol;
- Provides traceable European documentation;
- Resists pressure washing, salt and vibration.
The cheapest fixture price can become the most expensive project when installation, traffic management and maintenance access are included.
German and European requirements buyers should understand
DIN 67524
DIN 67524-1 covers quality characteristics and reference values for road-tunnel and underpass lighting. DIN 67524-2:2025-06 covers calculation and measurement of the lighting characteristics addressed by Part 1.
Compliance is not demonstrated by a product datasheet alone. The complete tunnel design must account for the entrance, threshold, transition, interior and exit conditions.
ATEX and explosion protection
Equipment intended for explosive atmospheres may fall under ATEX Directive 2014/34/EU and the relevant EN IEC 60079 standards. The equipment group and protection concept must match the actual mine or industrial zone.
An ATEX marking for a gas or dust environment does not automatically prove suitability for every underground mine.
CE documentation
CE marking is a legal conformity framework, not a general quality award. Buyers should obtain the EU Declaration of Conformity and identify the directives and harmonized standards applied to the exact model.
Emergency and evacuation lighting
Normal tunnel illumination, emergency lighting and route guidance have different functions. Their power supplies, operating modes and visibility criteria should be specified separately.
Seven factors to compare before ordering
1. Photometric files
Request current LDT or IES files for the exact LED, optic, power and colour-temperature configuration.
2. Control compatibility
Confirm DALI, 1–10V, switching, sensor input, monitoring and emergency-control requirements before production.
3. Corrosion resistance
Road tunnels expose fittings to moisture, exhaust deposits, cleaning chemicals and de-icing salts. Confirm housing, fastener and coating suitability.
4. Pressure washing
An IP rating alone may not describe resistance to close-range high-pressure cleaning. Ask for the relevant test method and permitted cleaning procedure.
5. Long-run voltage drop
For continuous strip, calculate the actual current, cable size, feed spacing and maximum run. Buyers can compare Xmart’s 24V, 36V and 48V systems when defining the electrical layout.
6. Replaceable components
Confirm whether drivers, LED modules, connectors and damaged strip sections can be replaced without removing the complete installation.
7. Certification ownership
The name on the certificate, product label, invoice and Declaration of Conformity should form a traceable chain.
When LED strip is appropriate in a German tunnel project
Continuous LED strip can be effective along service corridors, cable galleries, conveyor routes, construction passages and directional paths. It reduces dark gaps and can create a visually continuous escape direction.
It is usually not a direct replacement for engineered road-tunnel luminaires. It is also not automatically suitable for explosive mining environments merely because it is sealed and impact resistant.
For a custom non-classified continuous system, contact Xmart with the route drawing, voltage, run length, target illuminance, ambient temperature, connector preference, certification requirements and project quantity.
Final recommendation
Choose NORKA or SITECO for major German road-tunnel projects. R. STAHL is the strongest fit in this list when certified explosion protection and mining suitability are central requirements.
AEC and Broll are relevant to fixed road-tunnel luminaires and modernization. Rhomberg Sersa serves rail-tunnel and evacuation applications, while GIFAS provides temporary continuous lighting. Lightronics is strong in impact-resistant public tunnels, and Sagitar adds guidance and control expertise.
Xmart is best suited to distributors and contractors seeking a customizable continuous OEM system for non-classified underground or construction routes. The final decision should follow the application category, not the company’s size or the highest lumen figure.
Frequently asked questions
Who are the leading tunnel-lighting manufacturers in Germany?
NORKA and SITECO have some of the clearest dedicated tunnel portfolios and project evidence. The best supplier depends on whether the project is a road tunnel, rail tunnel, retrofit or public underpass.
Which German company supplies explosion-proof mining lights?
R. STAHL publishes explosion-protected LED tubular luminaires suitable for mining on applicable models. The exact mining category and certificate must be verified.
Can a mining LED strip be imported into Germany?
Yes, but the importer must ensure that the complete product and documentation meet all applicable EU requirements. For explosive atmospheres, ordinary CE and IP claims are insufficient.
Is IP67 or IP68 enough for a tunnel?
No. A tunnel specification may also require photometric performance, impact resistance, corrosion resistance, pressure-washing suitability, fire behaviour, control compatibility and emergency operation.
What is DIN 67524?
It is the German standard series addressing road-tunnel and underpass lighting quality, calculation and measurement.
Can LED strip replace road-tunnel lights?
Usually not for primary traffic illumination. Continuous strip is more commonly used for service routes, construction passages, guidance or supplementary lighting.
What should a German RFQ include?
Include the tunnel type, drawings, traffic speed, existing mounting, electrical supply, required luminance, control protocol, environment, certification, emergency function, quantity and installation schedule.
