Cable assemblies for technical lighting and luminaires
We supply lighting cable assemblies — assemblies and interconnect components — to manufacturers of lighting equipment and, when the project requires it, to professional integrators who need assemblies defined by length, connection and conditions of use. When lengths, connectors, identification and conditions of use are defined from the product, the assembly can be repeated without redesigning it at every installation.
What this industry needs
What lighting cable assemblies demand in technical lighting equipment
In lighting equipment the connection assembly works with limited space, temperature and, often, repeated connection and disconnection cycles. The choice of connector and the quality of the crimp determine how many cycles the assembly withstands before it starts to give false contacts.
- Available space and integration inside the equipment
- Service temperature around the driver and the module
- Expected connection and disconnection cycles
- Environment and handling conditions over the life of the equipment
Industry requirements
What to define in a lighting cable assembly
Each project requires different criteria. We confirm them with your documentation before quoting, not after.
- Voltage, current and function specified by the equipment manufacturer
- Conductor, cross-section and type of cable required
- Connector, termination and length of each assembly
- Identification, grouping and assembly direction
- Environment, movement and documentation requirements
Common applications
Where lighting cable assemblies come in
From the internal wiring of a luminaire to the pre-connectorised assembly that repeats identically on every unit of a series.
Luminaire and driver
Connection between the power input, the driver and the lighting module, with the interface and power defined by the equipment manufacturer.
Internal interconnection of the equipment
Connections to modules, sensors, control electronics or auxiliary elements, according to the architecture defined by the manufacturer.
Assemblies repeatable in series
When the same part number is fitted on every unit of a series, the assembly is supplied with the length, termination and identification agreed for that configuration.
Equipment for professional or outdoor applications
If the equipment works outdoors or under specific conditions of temperature, humidity, UV radiation or handling, those conditions must be built into the specification of the assembly.
What is what
Lighting cable assemblies: internal, pre-connectorised and installation cabling
Not all the cabling of a lighting system serves the same function. It is worth distinguishing the assembly integrated in the equipment, the pre-terminated connections between defined elements and the cable that forms part of the installation.
Internal cabling of the equipment
It forms part of the architecture of the luminaire or lighting equipment: power, driver, modules, sensors or auxiliary elements according to the specification defined by the manufacturer.
Pre-connectorised assemblies
Lengths, connectors and terminations can be defined in advance to obtain repeatable assemblies and reduce preparation during integration or installation. The manufacturer makes the assembly and Justicia Marin coordinates its supply according to the agreed configuration.
Installation cabling
The cable that forms part of the electrical installation serves a different function from the internal cabling of the equipment and may be subject to specific requirements of the installation, the site and the applicable regulations. When a cable is intended to be permanently incorporated into a construction work, requirements of the European construction products framework and of the relevant specification may apply.

How we work for this industry
How we coordinate lighting cable assemblies
The better the assembly is defined, the fewer variables remain open at integration.
You pass us the specification
Part numbers, lengths, connectors, conditions of use and requirements applicable to the equipment or the application.
We compare alternatives
We compare cable, connector and termination alternatives that meet the specification defined for the project.
Manufacture of the assembly
We coordinate manufacturing and supply with the selected manufacturer, with the lengths, terminations and identification agreed. The checks needed are defined for the project and agreed with that manufacturer.
Supply and replacement
The agreed configuration is used as a reference for later supplies for as long as the part numbers remain available. If one becomes obsolete, a potentially compatible alternative can be studied: the differences are compared and, where appropriate, the customer validates the change. Substitutions are not automatic.
What we actually do in this industry
Justicia Marin is a distributor: we understand the requirement, compare alternatives and coordinate the supply through a network of manufacturers. We have no factory, warehouse or laboratory of our own, and we issue no certifications: certificates are always those of the relevant manufacturer or supplier. The checks needed are defined for the project and agreed with the manufacturer that makes the assembly; when documentation of those checks is required, we coordinate its availability. We do not carry out installation, on-site assembly or lighting design.
The IP rating of a connector or component does not by itself determine the degree of protection of the luminaire or the final system: sealing requirements must be defined for the application and validated on the corresponding product or system. If the manufacturer defines requirements derived from IEC/EN 60598 or another standard applicable to the luminaire, they are incorporated into the specification of the assembly and into the manufacturer selection criteria.
Questions from luminaire manufacturers
Lighting cable assemblies: frequently asked questions
- Which cable assemblies do you supply for lighting?
- Internal wiring of luminaires, connections between power supply, driver and LED module, pre-assembled cable assemblies with connectors at length, and connections to sensors or control. They are made to the manufacturer’s specification by a manufacturer that we select, and delivered per part number for series production.
- What do you look at in cable assemblies around LED drivers?
- The operating temperature around driver and module, the current per connection, the available space and the number of times the connector is connected and disconnected. These data determine the choice of cable, insulation, connector and crimp connection. We record them in the specification before manufacturers are compared.
- Does an IP67 connector guarantee a waterproof luminaire?
- No. The IP rating of a connector applies to that component; the tightness of the luminaire depends on housing, glands, seals and assembly and must be demonstrated on the final product according to IEC 60529. State the rating required for the luminaire, and the components are then chosen accordingly.
- Do you also supply installation cable for buildings?
- Our focus is the cabling in and between lighting equipment, not installation cable for buildings. Cable that is permanently incorporated into a construction work falls under its own requirements, such as those of the European framework for construction products. We provide no installation, on-site assembly or lighting design.
- How does an assembly stay identical in every series?
- The agreed configuration — length, connector, finish, marking and checks — is recorded per part number and revision. The manufacturer works from it on every order. If a component becomes obsolete, alternatives are compared and the equipment manufacturer validates the change before it is applied.
- What do you need for a quote?
- Voltage, current and function of the assembly, cable type and cross-section, connectors and finishes, lengths, marking, environment and conditions of use, the quantity and expected repeat orders. A drawing or sample helps. If information is missing, we tell you which before approaching any manufacturer.
- Who makes the lighting cable assemblies?
- A manufacturer that we select based on the assembly, the volume and the checks requested. Justicia Marin compares alternatives, coordinates delivery and documentation and checks part number and quantity on receipt. We have no production, warehouse or laboratory of our own; certificates are those of the manufacturer.
Do you make or integrate lighting equipment?
Tell us which assembly you need to repeat.
With the specification of the assembly we compare manufacturers that can meet it. Cost, target lead time, availability and documentation are compared afterwards, among those that meet the technical requirements. If you want to prepare your enquiry, in how to request a quote we explain what information is needed.
