The brightest tunnel is not necessarily the safest tunnel. Excessive intensity, poor optical control and repeated bright-dark patterns can increase glare and visual fatigue instead of improving visibility.
The expensive failures are often less obvious. A road-tunnel luminaire can have excellent efficacy but poor entrance-zone control. A mining strip can be waterproof along its body yet fail at a connector. A rail fitting can produce enough light but become impractical when maintenance access is restricted.
This guide compares 10 specialist manufacturers and suppliers serving the United Kingdom. It covers road and rail tunnels, underground routes, hazardous locations and industrial LED strip systems. Companies are ranked by technical relevance, UK-market capability and available application evidence—not by turnover or sales volume.

How the companies were selected
Each company needed verifiable evidence of at least one of the following:
- A dedicated tunnel or transport-infrastructure luminaire;
- A mining, hazardous-area or explosion-protected lighting range;
- Rail-sector experience with robust or anti-vandal lighting;
- Industrial continuous lighting developed for tunnels or underground routes;
- Custom long-run LED strip manufacturing suitable for professional projects.
General decorative LED strip sellers were excluded. The list also separates flexible systems from primary tunnel luminaires because the two product categories perform different lighting tasks.
1. Raytec
Raytec is a British manufacturer of hazardous-area and industrial LED lighting based in Northumberland.
Its hazardous range includes products for Zone 1, Zone 2 and other demanding environments, with ATEX and IECEx options across linear, bulkhead, flood and area-lighting formats. The company also develops lighting for industrial inspection and security applications.
Raytec does not manufacture conventional flexible tunnel strip. Its strength is certified fixed lighting for areas where a standard waterproof product cannot provide the required hazardous-location protection.
Best for: Hazardous industrial tunnels, processing areas and fixed lighting in classified locations.
Company location: United Kingdom
2. Chalmit
Chalmit is a UK hazardous-area lighting specialist with a long history in heavy industry.
Its portfolio includes explosion-protected linear luminaires, floodlights, bulkheads, emergency products and products designed for corrosive or high-risk locations. Chalmit products are widely associated with oil and gas, marine, energy and other hazardous industries.
For mining and underground projects, Chalmit is most relevant where the specification requires certified rigid lighting rather than flexible strip.
Best for: ATEX or IECEx projects, hazardous industrial areas and explosion-protected linear lighting.
Company location: United Kingdom
3. Designplan Lighting
Designplan is a British manufacturer specializing in robust lighting for rail, secure and high-abuse public environments.
Its experience includes railway platforms, stations, transport infrastructure and products designed to resist vandalism, impact and difficult environmental conditions. This is directly relevant to rail tunnels and underground transport areas where mechanical durability and restricted maintenance access matter.
Designplan is not a mining LED strip company. It is included for permanent rail and transport lighting where tested rigid luminaires are the appropriate solution.
Best for: Rail infrastructure, underground stations, service passages and high-abuse transport locations.
Company location: United Kingdom
4. Xmart Lighting
Website: www.xmartlightings.com
Xmart Lighting manufactures custom tunnel and mining LED strip systems through production facilities in China and Vietnam.
The company’s Tunnel & Mining LED Strip is available in 24V, 36V and 48V versions. Published product features include IP67 sealing, IK10 impact resistance, silicone extrusion and pre-terminated reels.
Xmart’s main role in the UK market is OEM and project manufacturing. Reel length, power, colour temperature, connectors, packaging and branding can be adapted for distributors and contractors. Standard models should not be presented as UKEX, ATEX or emergency-lighting products unless the exact configuration carries the required certification.
Best for: OEM supply, private labels, long non-classified routes, cable tunnels and industrial service passages.
Company location: China and Vietnam
Product range: View Xmart tunnel and mining LED strip systems
5. Schréder UK
Schréder supplies professional road, tunnel and infrastructure-lighting systems in the UK.
Its tunnel portfolio includes entrance, interior and continuous-line solutions as well as control technology. These systems are designed around tunnel luminance, visual adaptation, uniformity, energy use and maintenance.
Schréder is a stronger candidate for primary road-tunnel lighting than a flexible strip producer. Continuous linear products can improve guidance, but the central value is controlled photometric performance for drivers.
Best for: Road tunnels, tunnel entrances, primary traffic lighting and intelligent controls.
Market role: International infrastructure manufacturer with UK operations
6. Holophane Europe
Holophane Europe manufactures professional infrastructure lighting in the United Kingdom and has a long association with roads, tunnels and large public projects.
Its tunnel products and project capabilities focus on high-output optical control, durable construction and lighting systems for demanding transport environments.
Holophane is most appropriate when the project requires conventional engineered tunnel luminaires rather than a flexible guidance or walkway strip.
Best for: Primary road-tunnel illumination, entrances, underpasses and major infrastructure schemes.
Company location: United Kingdom
7. Thorn Lighting
Thorn is a professional lighting brand with a strong presence in the UK transport and infrastructure market.
Its tunnel and underpass products are designed for permanent installations requiring controlled distribution, durability and efficient maintenance. The wider portfolio also covers roads, rail-adjacent areas and industrial spaces.
Thorn should be compared with Schréder and Holophane for primary infrastructure lighting, not with flexible mine-strip systems.
Best for: Road tunnels, underpasses, transport infrastructure and conventional fixed illumination.
Market role: Professional lighting brand serving the United Kingdom
8. x-Glo
x-Glo is a specialist industrial LED strip brand developed for underground mining, tunnelling and other harsh environments.
Its range includes low-voltage continuous lighting and ATEX/IECEx Exm products for hazardous locations. The systems are intended for wet, corrosive, vibration-prone and high-impact applications.
For UK buyers, x-Glo is relevant when a project needs a mature industrial strip system rather than an adapted architectural LED tape.
Best for: Underground industrial routes, mining applications and projects requiring an explosion-protected strip option.
Market role: International mining-lighting specialist
9. MineGlow
MineGlow supplies industrial LED strip systems for mines, tunnels, conveyors, emergency guidance and hazardous locations.
The range includes 24V and 36V products, a 48V tunnel system, explosion-protected options and emergency signalling. MineGlow also supplies connectors, repair kits, power equipment and mounting components.
That complete-system approach is important for UK tunnels because connector integrity, fire strategy, emergency operation and replaceable sections can matter more than nominal strip brightness.
Best for: Long-distance industrial strip lighting, conveyors, emergency guidance and complete tunnel packages.
Company location: Australia; serves international projects
10. Dialight
Dialight is headquartered in the United Kingdom and manufactures industrial and hazardous-location LED lighting.
Its portfolio includes certified linear luminaires, high bays, floodlights, bulkheads, area lights and emergency products. These are relevant to processing plants, maintenance facilities, utilities and classified industrial areas.
Dialight is not a flexible tunnel-strip manufacturer. It is included as a professional fixed-lighting alternative where certification, thermal control and long service life are more important than physical flexibility.
Best for: Hazardous industrial locations, processing areas, fixed linears and high-maintenance sites.
Company location: United Kingdom / international operations
What UK tunnel projects often get wrong
Tunnel lighting is sometimes treated as a single application. In reality, a motorway tunnel, railway tunnel, pedestrian underpass, utility tunnel and mining decline have different users, visual tasks and regulations.
The more useful starting questions are:
- Is the lighting for drivers, workers, evacuation or maintenance?
- Is the route a road, rail, utility or industrial tunnel?
- Does the area require UKEX, ATEX or IECEx equipment?
- What fire, smoke and material requirements apply?
- How will the system operate during loss of normal power?
- Can drivers or workers see obstacles without reflected glare?
- Can a failed section be isolated without darkening a long route?
A product cannot be called suitable simply because it is bright and waterproof.
Seven factors to compare
1. Optical task
Primary road-tunnel lighting requires controlled luminance and entrance adaptation. A continuous strip is more naturally suited to guidance, walkways and service routes.
2. Glare and bright-dark repetition
Widely spaced intense fixtures can create repeated changes in brightness. Continuous lighting may reduce this effect, but it still needs suitable output, mounting and diffusion.
3. Long-run electrical design
For long non-classified service routes, buyers can compare Xmart’s 24V, 36V and 48V systems according to route length, cable size and available feed points.
4. Fire and emergency requirements
Housing, cable, connectors and mounting materials may all form part of the fire strategy. Normal industrial strip should not be described as an emergency-lighting system without the required testing and system design.
5. Certification scope
UKCA, CE, UKEX, ATEX and IECEx address different requirements. An IP rating does not prove explosion protection, flame performance or emergency compliance.
6. Maintenance and isolation
Drivers, connectors and replaceable sections should be accessible. A local failure should not require replacing or switching off an entire tunnel route.
7. Manufacturer versus system supplier
A strip manufacturer, hazardous luminaire company and tunnel-control specialist provide different capabilities. Procurement documents should assign responsibility for photometry, power, emergency operation, controls, connectors and installation.
When flexible LED strip is appropriate
Industrial strip can work well in cable tunnels, service passages, conveyor routes, handrails, construction tunnels and evacuation guidance. Its continuous light can reduce dark gaps and clarify the direction of travel.
It is not automatically suitable for primary road-tunnel lighting, Network Rail infrastructure or a hazardous atmosphere. Those applications may require approved rigid luminaires, project-specific testing and formal acceptance.
Local supplier or OEM manufacturer?
UK manufacturers provide local engineering, standards familiarity and project support. An OEM producer offers customization, private-label supply and control over voltage, length and packaging.
The two routes are not mutually exclusive. UK distributors and contractors can define the local compliance and project requirements, then contact Xmart when a standard product does not provide the required long-run or OEM configuration.
Final recommendation
Choose Raytec or Chalmit when hazardous-area lighting is the main requirement. Designplan is particularly relevant to rail and high-abuse transport environments.
Schréder UK, Holophane and Thorn are better aligned with primary road-tunnel and infrastructure illumination. x-Glo and MineGlow offer established specialist strip systems.
Xmart is best suited to distributors and contractors seeking a configurable long-run product for appropriate non-classified routes. For a project review, send Xmart the route length, voltage, target illuminance, area classification, environment and estimated quantity.
Frequently asked questions
Who manufactures tunnel lighting in the UK?
Several companies serve the UK market. Designplan, Holophane and Dialight have UK manufacturing or headquarters, while Schréder, Thorn, Raytec and Chalmit provide specialist infrastructure or hazardous lighting.
Can normal waterproof LED strip be installed in a tunnel?
Not automatically. The complete system must meet the project’s electrical, mechanical, fire, emergency and environmental requirements.
Is UKEX the same as an IP rating?
No. UKEX addresses equipment for explosive atmospheres in Great Britain. An IP rating only describes protection against ingress under specified test conditions.
What voltage is suitable for a long service tunnel?
It depends on the route, power, cable size and available feed points. A 36V or 48V system may reduce current and voltage drop compared with 24V, but the complete installation must comply with project rules.
Can continuous LED strip replace road-tunnel luminaires?
Usually not for primary traffic illumination. Road tunnels require controlled optical performance and entrance-zone design. Strip lighting is more often used for guidance or secondary routes.
Is Xmart a UK company?
No. Xmart manufactures in China and Vietnam and supplies international OEM and project customers. It is included as a custom manufacturing option for UK importers, distributors and contractors.
What should a buyer include in an enquiry?
Include tunnel type, route drawings, voltage, run length, target illuminance, fire requirements, area classification, emergency operation, connector preference and quantity.
