Construction String Lights Manufacturers

What We Supply in the Lighting Range

Our lighting program is built around three product families that share the same cable, molding and assembly disciplines as our power cord business. We produce the cord, socket, switch and plug in-house, which keeps lead times and quality control under one roof.

Application Fit by Product Type

Each family addresses a different working environment. The table below maps our current lighting products to typical applications and the specification points we confirm before quoting.

Materials and Construction

Lighting products carry the same electrical safety requirements as power cords. We mold our own plugs and sockets from flame-retardant PVC and use stranded copper conductors sized to the current and run length of each configuration.

• Conductors: stranded copper, AWG selected against total load and voltage drop over the run.
• Insulation and jacket: PVC or rubber compounds matched to indoor or outdoor use.
• Molded parts: plug, socket and switch bodies produced on our own molding lines.
• Lamp heads: LED modules with impact-resistant housings and integrated heat management.
• Hardware: hooks, hangers and strain relief selected for the mounting method.

Capacity, Accuracy and Quality Control

Our lighting components are produced on automated assembly lines with in-line testing. Every production stage is subject to documented quality control under our ISO 9001 Quality Management System, and our testing lab verifies electrical performance before shipment.

• Continuity, polarity and high-potential testing on assembled cords and string sets.
• Dimensional and pull-force checks on molded plugs, sockets and strain reliefs.
• LED module function and color consistency checks on string light and work light assemblies.
• Certificate of Compliance records maintained for c(UL)us, ETL and CE covered products.

Configuration and Customization

We develop lighting products from customer drawings or samples. Our R&D team works from the working point, mounting method and target market to define the cord, socket, switch and plug combination.

Installation, Safety and Maintenance

String lights and work lights are installed by the end user, so we design for straightforward mounting and safe handling. Strain relief and molded connections reduce pull stress on terminals, and replaceable lamp heads extend service life on site.

• Hooks and hangers sized for the lamp weight and mounting surface.
• Switch and receptacle covers positioned for safe access during use.
• Spare lamp heads, sockets and cord sets available as service components.
• Product manuals and installation guidance supplied with each order.

Information We Use to Configure Your Solution

To prepare a lighting configuration and quotation, we work from the following project inputs. The more precisely these are defined, the faster we can confirm the cord, socket and lamp combination.

• Application and mounting environment (indoor, outdoor, wet, temporary or permanent).
• Required lamp wattage, number of lamps and total run length.
• Supply voltage, frequency and plug standard for the destination market.
• Switch, receptacle and control requirements.
• Target certification and any customer-specific marking or packaging.
• Annual volume, order pattern and delivery destination.
• Drawings, samples or reference products for custom development.

Related Connection Products

Lighting installations often require matching power and extension components. We supply these from the same manufacturing base, which simplifies procurement and keeps certification consistent across the project.

• Power cord assemblies for fixtures and equipment.
• Extension Cord options for temporary power distribution.
• LED String Light models for construction and event use.

Frequently Asked Questions

What lighting products does Zhenjia manufacture?

We manufacture LED string lights, LED work lights and lamp cords, along with the molded plugs, sockets and switches used in these assemblies. Our lighting range is produced in the same facilities as our power cords and EV charging products.

Can you produce lighting products to our drawings or samples?

Yes. Our R&D team develops and produces products according to customer drawings or samples. We confirm the electrical and mechanical specification, then build samples for approval before production.

Which certifications apply to your lighting range?

Our products hold key safety certifications including c(UL)us, ETL and CE, and our facilities operate under the ISO 9001 Quality Management System. The applicable certification depends on the product configuration and destination market, and we confirm this during quotation.

Do you supply lamp cords and string light sockets separately?

Yes. We supply lamp cords, string light sockets and wiring as components for OEM assembly as well as complete string light and work light products. Component supply is useful for customers who assemble fixtures in their own facility.

What information do you need to quote a lighting project?

We need the application, lamp wattage and quantity, total run length, supply voltage and plug standard, switch or receptacle requirements, target certification, annual volume and delivery destination. Drawings or samples help us confirm custom configurations.

How are lighting products packaged and delivered?

Packaging is defined with the customer and can include retail-ready cartons or bulk packing for OEM assembly. We confirm carton dimensions, labeling and pallet configuration as part of the order specification.
