Every custom light installation passes through eleven distinct stages before it arrives at your venue. Understanding this process helps you plan timelines, anticipate dependencies, and see why quality installations require both craftsmanship and time.
Here is the complete journey — from the first design sketch to the final on-site test.
How Are Custom Light Installations Actually Made?
Direct Answer: Every custom light installation we produce follows an 11-step making process rooted in Zigong lantern craft: design and 3D rendering, construction planning for modular transport, steel frame fabrication, anti-rust coating, LED wiring and lighting installation, silk or fabric covering, hand-painted detailing, final quality testing, modular packaging for shipping, on-site assembly, and a final illumination test. Each step follows standardized quality controls to ensure the finished piece matches the design specifications with 90%+ accuracy.
This process is documented in provincial standard DB51/T 2939 and applied to every project we deliver — whether it‘s a 5-meter mascot or a 40-meter dragon.
Step 1: Design — Translating Ideas into Buildable Blueprints
Our designers — including professors from the China Lantern Academy — use CAD and 3D rendering tools to transform your concept into precise technical drawings. Every visual element — color gradients, light diffusion patterns, and proportional relationships — is mapped before production begins.
For large-scale events across multiple zones, we create layout plans that map how installations will work together visually and guide visitor flow. This planning stage ensures that what looks good as a single piece also works as part of a coordinated experience.
Step 2: Construction Planning — Engineering for Transport and Assembly
Once the design is approved, we break each installation into modular components. This engineering stage addresses three practical realities: the pieces must fit inside standard shipping containers, withstand the structural loads of their own weight and local wind conditions, and assemble efficiently on site.
The plans produced at this stage determine how your installation will travel from our factory to your venue — and how quickly it can be ready once it arrives.
Step 3: Frame Building — Shaping the Steel Skeleton
Master welders from our artisan team hand-shape high-grade steel — meeting GB/T 1591 structural standards — into the three-dimensional framework that gives each installation its form. Every curve, every angle, and every joint must match the design specifications exactly.
The welding process follows GB 50661, the national standard for steel structure welding. Each welded joint must withstand at least 50% of the tensile strength of the base wire, as specified in DB51/T 2939. The artisans continuously check the developing framework against the original design, making hands-on adjustments that machines cannot replicate.
Step 4: Rust Prevention — Protecting the Structure
Outdoor installations face rain, humidity, and coastal salt. After welding, every frame undergoes sanding and industrial anti-rust treatment — a process that meets DB 5103/T 43, the provincial standard for corrosion protection of Zigong lantern metal structures.
This step is not cosmetic. It determines whether your installation will still look pristine after weeks or months of outdoor exposure. Our treatment process is proven across projects in Kuwait’s coastal environment and Sydney‘s waterfront — both environments that accelerate corrosion in unprotected steel.
Step 5: Wiring and Lighting — Integrating the Glow
Electrical engineers weave insulated wiring through the steel frame, positioning energy-efficient LEDs to highlight key features of the design. Warm LEDs create traditional atmospheres for cultural installations. Color-changing LEDs produce dynamic effects for modern commercial events.
Every component meets electrical safety standards: insulation resistance exceeds 0.5MΩ, and protective earth resistance stays below 4Ω. Every individual bulb is tested before installation — a quality check that prevents dark spots and ensures even illumination across the entire surface.
Step 6: Surface Covering — Adding Color and Texture
Artisans wrap the frame in silk for soft light diffusion, or in waterproof polyester for outdoor durability. The choice of material depends on your venue: indoor installations prioritize texture and subtlety, while outdoor pieces require weather resistance above all.
All fabrics meet GB/T 18885, the ecological textiles standard. Adhesives comply with GB 18583, ensuring harmful substance limits are not exceeded. The covering must be smooth, wrinkle-free, and free from stains — with no exposed glue marks exceeding 0.5cm at any seam.
Color-block plans guide the application, ensuring that the final piece matches the intended visual identity.
Step 7: Hand-Painting — Adding Personality
Master artists hand-paint every detail — scales, facial features, patterns, and gradients — directly onto the fabric surface. Spray techniques handle large areas evenly, while brushwork captures the fine details that make installations feel alive.
This stage is where Zigong lantern craft becomes visible. The difference between a generic shape and a recognizable character often comes down to the quality of hand-painting at this step.
Step 8: Final Testing — Verifying Every Detail
Before shipping, every installation undergoes a full light test. We check color accuracy against the original design, confirm even light distribution across the entire surface, and verify structural stability under operational conditions.
The acceptance standard requires a minimum 90% visual restoration of the original design, as specified in DB51/T 2939. Each installation runs for two hours continuously to verify electrical stability and thermal performance. Adjustments are made until the piece meets quality standards. This is the last checkpoint before your installation leaves the factory — and nothing ships until it passes.
Step 9: Packaging — Protecting for Global Transport
Large installations are disassembled into labeled modules, each wrapped in protective material and secured for shipping. We partner with global logistics providers and handle all customs documentation to ensure smooth clearance at destination ports.
Every component is labeled for reassembly — so when the pieces arrive at your venue, the installation team knows exactly how they fit together.
Step 10: On-Site Installation — Bringing It All Together
For large installations, our certified installation team travels to your venue to reconstruct modules, connect wiring, and run final quality checks. For smaller pieces, we provide detailed installation guides and remote support.
In either case, the goal is the same: your installation should look exactly as designed, with zero surprises on event day.
Step 11: The Finished Installation — Your Vision, Illuminated
The result is not a generic decoration. It is a custom-built, engineered, and hand-finished installation designed for your specific event, your specific venue, and your specific audience — a living expression of Zigong lantern craft applied to modern events.
What This Process Means for Your Event Timeline
Direct Answer: Understanding these eleven steps helps you plan realistically. The in-factory production phase typically runs 20–45 days, depending on project complexity and scale. International shipping and on-site installation vary by destination and are assessed case by case. The more lead time you can provide, the more options you have at every stage.
We work backward from your event date to build a timeline that accommodates every stage without compromise. The process cannot be rushed — but it can be planned. And the earlier you start the conversation, the more flexibility we have to deliver exceptional results.
