ledTec.flex is an ultra-light, thin LED wall foil for digitalizing existing surfaces. Unlike conventional LED cabinets, ledTec.flex is not mounted as a heavy box in front of a surface — it is integrated as a flexible digital layer onto existing supports, façades, pylons, advertising surfaces or custom structures.

The key difference: we don't necessarily create a new structure. We make existing surfaces digitally usable.

Conventional LED walls usually consist of heavy, rigid cabinets with their own support structure. ledTec.flex is significantly lighter, thinner and can be integrated much closer to the surface.

In practice, that means:

• less weight
• less material
• smaller transport volume
• lower structural load
• easier integration into existing assets
• better suitability for retrofit projects
• often a smaller structural intervention

For existing advertising surfaces, pylons, façades or special formats, this can be a decisive advantage.

ledTec.flex is especially suited to projects where existing surfaces are to be digitalized, for example:

• fuel station pylons and price totems
• 18/1 billboard surfaces
• façades and building elements
• retail surfaces and shop windows
• shopping mall surfaces
• event and stage applications
• lightweight custom structures
• temporary or semi-permanent installations
• indoor and outdoor applications, depending on the product version

Its strongest use case is wherever conventional LED cabinets would be too heavy, too deep, too expensive or too structurally invasive.

Technically, ledTec.flex is an LED-based digital display surface. Strategically, however, it is not a conventional LED wall but an LED wall foil: a thin, light and modular layer of light.

This matters because it changes the project logic. It is not just about a display, but about the digital upgrade of a surface that already exists.

Depending on the application, various pixel pitches are available — for example for indoor, semi-indoor and outdoor use.

Typical logic:

• fine pixel pitch for short viewing distances
• medium pixel pitch for retail, mall and event
• larger pixel pitch for outdoor advertising, pylons and long-range visibility

As a rule of thumb: the closer the viewer, the finer the pixel pitch should be. For large outdoor surfaces, fuel station pylons or 18/1 surfaces, the finest pixel pitch is often not the decisive factor — rather, it's the right balance of image impact, cost, energy consumption and viewing distance.

The required brightness depends heavily on the location:

• indoor: lower brightness, but high visual comfort
• semi-indoor or covered areas: medium brightness
• outdoor in daylight: higher brightness and automatic dimming
• direct sunlight: project-specific assessment required

What matters is not only the maximum brightness, but the visual impact under realistic operation. LightnTec therefore considers brightness, contrast, energy consumption, environment, viewing angle and any regulatory requirements together.

Weight is one of the biggest advantages of ledTec.flex. Many existing surfaces were never built to carry heavy LED cabinets. The lighter the digital layer, the easier the integration.

This can bring advantages for:

• structural engineering
• support structure
• transport
• installation
• permitting arguments
• removability
• total cost

In retrofit projects in particular, weight is not just a technical point — it is often the commercial and regulatory key.

Yes — this is one of its central strengths. ledTec.flex was developed for the digitalization of existing surfaces.

Typical examples:

• existing billboard surfaces
• existing pylons
• façade surfaces
• banner or frame structures
• architectural surfaces
• retail and mall surfaces

The actual feasibility depends on the surface, substrate, size, structural load, power supply, accessibility, environment and permitting situation.

Yes, there are outdoor versions. For outdoor applications, however, several factors must be assessed:

• IP protection
• temperature range
• humidity
• UV exposure
• wind loads
• support structure
• cable routing
• power supply
• maintenance access
• local permitting requirements

Outdoor projects are therefore always evaluated on a project-specific basis.

The protection rating depends on the specific product version and application. Weatherproof solutions are designed for outdoor installations. What matters is not only the protection rating of the LED surface, but the overall system of ledTec.flex, cabling, power supply, mounting, sealing and maintenance concept.

For projects with high humidity, coastal proximity, dust, heat or particular mechanical stress, the specification should be assessed separately.

Installation depends on the project. In principle, ledTec.flex can be integrated onto suitable support surfaces or substructures. The goal is the lightest, flattest and most reversible solution possible.

Depending on the application, options include:

• direct integration onto backing panels
• mounting on existing frames
• integration into existing advertising media
• modular substructures
• custom mounting systems

In many projects, the installation is considerably less massive than with conventional LED cabinets.

Yes — removability is an important part of the retrofit logic. ledTec.flex is designed to digitally upgrade existing surfaces without necessarily altering them permanently.

This is especially relevant for:

• rented spaces
• permitted existing installations
• temporary installations
• shopping malls
• fuel stations
• advertising media with existing structures
• locations with a sensitive permitting situation

ledTec.flex can be operated with professional LED control systems. The exact selection depends on the application, resolution, content logic, brightness control, synchronization and operating model.

Typical requirements:

• reliable content playback
• automatic brightness control
• stable signal processing
• remote maintenance
• monitoring
• easy integration into existing media or DOOH systems

For simple applications, a lightweight control setup may be sufficient. For DOOH networks or large installations, a professional operating and monitoring concept is required.

Yes. ledTec.flex is particularly interesting for digital out-of-home advertising because existing analog advertising media can be digitalized.

The commercial advantage is that an existing surface can become a digital media channel. As a result, the surface can be monetized multiple times, run more dynamic content and be integrated more effectively into modern DOOH networks.

In short: an existing surface becomes digital infrastructure.

Fuel station pylons are existing, highly visible and often already permitted communication surfaces. With ledTec.flex, these surfaces can be digitally upgraded without necessarily building a heavy additional LED screen alongside.

Possible applications:

• digital price and offer communication
• shop and convenience promotions
• e-mobility and loyalty communication
• local advertising
• national campaigns
• additional media revenue

The pylon doesn't just become more modern — it can become a new digital profit center.

Yes — 18/1 surfaces are a very natural use case. The surface is already visible, often well established and commercially usable. ledTec.flex can help upgrade such existing surfaces digitally without necessarily adopting the logic of a heavy LED cabinet.

The advantage lies in the combination of:

• an existing advertising surface
• digital monetizability
• lower weight
• shallower structural depth
• potentially simpler integration
• better scalability

Energy consumption depends on pixel pitch, brightness, content, time of day, dimming and operating hours. LightnTec does not treat energy efficiency in isolation as a marketing claim, but as part of overall economic viability.

What matters:

• lumen output per watt
• automatic brightness adjustment
• appropriate brightness rather than oversized peak values
• contrast impact
• lower transport and material load
• less structural work
• lower total cost over the lifetime

The key question is not only "how bright can the system be?" but "what visual impact is achieved with what energy and material input?"

The Deep Black Shader can improve perceived contrast and reduce stray light. As a result, a display can appear visually higher-quality under certain conditions without relying solely on maximum brightness as an argument.

This can be especially relevant for:

• outdoor applications
• permitting-sensitive locations
• surfaces with light emission requirements
• DOOH retrofit projects
• higher perceived image quality

Its use depends on the project and the product version.

Lifespan depends on the product type, operating hours, brightness, temperature, environment and maintenance. As with all LED systems: continuous operation at maximum output stresses the system more than intelligent, dimmed, location-adapted operation.

For LightnTec projects, therefore, what matters is not only the nominal LED lifespan but the entire operating concept:

• sensible brightness curves
• thermal design
• quality control
• maintenance access
• monitoring
• spare parts concept
• a realistic usage profile

ledTec.flex is designed for professional applications. The maintenance effort depends on location, size, accessibility and operating hours.

Typical maintenance topics:

• visual inspection
• cleaning depending on the environment
• checking power supply and signal paths
• replacing individual components as needed
• software and content system upkeep
• monitoring for larger networks

For larger rollouts, a local service and spare parts concept should be defined.

Yes. Technical documents are provided for projects, depending on the project phase and confidentiality status. These can include:

• product datasheets
• system drawings
• electrical requirements
• installation concept
• weight data
• power consumption
• control concept
• maintenance logic
• project-specific technical assessment

Detailed documents, custom designs or sensitive technical information are generally shared only after project qualification and, where applicable, under NDA.

For an initial assessment, the following are helpful:

• location and application
• indoor, outdoor or semi-indoor
• desired surface in width and height
• photos of the existing surface
• technical drawings, if available
• viewing distance
• desired brightness or usage situation
• on-site power supply
• planned content
• desired operating period
• installation and maintenance access
• permitting situation, if known

The more specific the information, the more realistic the technical and commercial assessment can be.

Both. ledTec.flex is based on modular technology but is often deployed on a project-specific basis. Many applications require adaptation to existing surfaces, frames, pylons, façades or special geometries.

LightnTec is therefore particularly strong on projects where a standard LED cabinet is not an optimal fit.

A typical project flow looks like this:

1. Initial project description
2. Assessment of application, surface and location
3. Initial technical evaluation
4. Definition of pixel pitch, brightness and system logic
5. Rough cost and feasibility assessment
6. Detailed technical planning
7. Quote and commercial structure
8. Production
9. Installation and commissioning
10. Operation, service and possible scaling

For rollout projects, a pilot or a zero-series run can also be worthwhile.

Yes. Pilot projects are often the best way to test technical feasibility, visual impact, installation concept, permitting logic and commercial potential in a real environment.

For new retrofit applications in particular, a pilot is often more useful than purely theoretical planning.

LightnTec has its own operational production in Karlsruhe. In addition, qualified manufacturing partners can be involved depending on the project and scaling needs.

For many customers this is important because engineering, customization, quality assurance and project development can take place close to the customer.

Yes. ledTec.flex can be deployed internationally. It is important, however, to assess each country and each location carefully — both technically and from a regulatory standpoint.

Points to clarify in particular:

• local standards
• electrical requirements
• permitting
• customs and logistics
• climate and environment
• service partners
• installation availability
• operating concept

Depending on the market and application, different forms of evidence may be required — for example CE, EMC, electrical safety, fire protection, IP protection or project-specific documentation.

The specific requirements depend on the product, location, installation concept and country. LightnTec clarifies this on a project-specific basis as part of the technical work.

In many cases, the retrofit logic can help the argument, because there isn't necessarily a new, massive advertising installation — instead, an existing surface is digitally upgraded.

What matters here:

• no unnecessary new building volume
• shallow structural depth
• low weight
• reversible integration
• controlled light emission
• appropriate brightness
• location-appropriate content rules
• clean technical documentation

Whether and how this is assessed under permitting law always depends on the location and the responsible authority.

That depends on the project. The pure price per square meter is not always the right comparison. What matters is the total cost of the project.

Relevant factors:

• display cost
• support structure
• structural engineering
• installation
• transport
• commissioning
• permitting
• power consumption
• maintenance
• operating model
• commercial use of the surface

In many retrofit applications, ledTec.flex can be very economically attractive, because existing assets can be reused and digitally monetized.

Depending on the project structure, various models are possible:

• purchase
• leasing
• sale-and-lease-back
• infrastructure model
• SPV model
• fixed monthly infrastructure fee
• revenue-share-based models
• operator or partner structures

Especially for DOOH and pylon retrofit projects, it can make sense to think not only in terms of hardware sales but in terms of long-term infrastructure and revenue models.

Because an existing surface can become an additional digital communication and revenue channel.

An analog surface shows one piece of content. A digital surface can show many pieces of content — time-controlled, updatable, more measurable and more commercially flexible.

The logic is simple: asset becomes platform, platform becomes cashflow.

LightnTec doesn't simply sell LED displays. LightnTec enables the digital upgrade of existing physical assets.

The core benefit lies in the combination of:

• ultra-light ledTec.flex technology
• retrofit integration
• low weight
• thin construction
• energy efficiency
• project-based engineering
• experience with special surfaces
• commercial platform logic

This is what clearly sets LightnTec apart from conventional LED screen suppliers.

LightnTec is especially relevant for:

• outdoor advertisers
• fuel station operators
• retail and mall operators
• infrastructure and real estate owners
• DOOH networks
• façade and architecture projects
• brands with existing physical surfaces
• integrators and project developers
• investors in digital infrastructure

Wherever an existing surface can be made digitally usable, there is a potential LightnTec use case.

The best way is with a concrete surface or a concrete use case.

Helpful inputs:

• photos
• dimensions
• location
• usage idea
• viewing distance
• indoor/outdoor indication
• technical drawings
• desired timeline
• commercial objective

On this basis, LightnTec can assess whether ledTec.flex can be deployed in a way that makes technical, commercial and strategic sense.
