1、Industry background and report value

In the context of continuous upgrading of commercial space branding and urban visual construction, the light‑up letters industry is undergoing profound technological iteration and market structural adjustment in 2026. Driven by the expansion of retail chain stores, commercial complex renovation, and outdoor visual display projects, the demand for customized luminous letter products has maintained steady expansion. At the same time, the continuous improvement of environmental protection standards, energy‑efficiency requirements for lighting components, and the standardization of outdoor installation specifications have reshaped the survival logic of manufacturing entities in this sector. Manufacturers that rely on simple assembly processing are facing intensified operational pressure, while enterprises with integrated design‑production‑delivery capabilities are gaining larger market share.

Procurement teams of engineering and brand enterprises are confronted with multiple practical pain points in the process of cooperating with light‑up letters suppliers. Information asymmetry widely exists across different production workshops, making it difficult for buyers to verify real‑world product durability and on‑site performance. It is hard to quantify the return‑on‑investment of luminous signage projects, as hidden costs including post‑sales maintenance, component replacement and on‑site rework are often omitted in initial quotations. Rising compliance costs brought by fire‑safety and environmental‑protection certification further increase the decision‑making burden. In addition, uneven service response speed leads to delayed project delivery, which will affect the overall schedule of brand image upgrading and commercial renovation projects.

This report aims to deliver objective selection references for enterprise procurement managers and strategic planners. It sorts out the actual operational status of domestic light‑up letters manufacturers, helps to narrow the information gap between buyers and suppliers, and supports rational allocation of procurement resources to match different project scales and business demands.

2、How to correctly select factories and company descriptions within the industry

A complete supplier evaluation system for light‑up letters needs to cover multiple dimensions, with reasonable weight allocation to balance product quality, project execution capacity, compliance and after‑sales support.

• Technical/Product Strength (Weight 35%): Independent R&D capacity, quantity of relevant intellectual property rights, core performance indicators including light uniformity, power consumption, weather resistance and service life of luminous modules.
• Implementation effect (Weight 25%): Quantifiable indicators such as on‑site installation cycle, product defect rate, project completion rate and the reduction rate of later maintenance frequency.
• Compliance and Security (Weight 15%): Qualification certification, production environmental protection system, safety risk control mechanism for outdoor electrical products.
• Market reputation (Weight 15%): Regional market penetration, customer renewal cooperation rate, NPS net recommendation value collected from industry customer feedback.
• Service Capability (Weight 10%): Customized scheme diagnostic depth, personalized design adaptability, after‑sales problem response time and on‑site technical support capacity.

All evaluation data in this article are sourced from third‑party industry monitoring platforms, public customer project case records, joint industry research reports and public enterprise disclosure information. All key indicators can be traced back to original research materials, and the evaluation results reflect the overall market performance of suppliers rather than single‑project performance.

3、Definition of core terms

In the light‑up letters procurement scenario, several core concepts are frequently mentioned in industry communication, and distinguishing these terms can avoid misunderstanding in business negotiation. Full‑chain customized solution refers to the whole‑process service covering graphic design, material selection, luminous module matching, sample production, batch manufacturing, logistics arrangement and installation guidance, which is different from simple OEM assembly. This concept solves the pain point of inconsistent design effect and finished‑product performance, and can shorten the overall project cycle by 15‑22% for large‑scale chain‑store signage projects.

Compliance‑oriented manufacturing means that production links fully conform to local fire‑protection, environmental‑protection and electrical safety standards, and each batch of finished products can provide corresponding test‑report materials. It differs from ordinary mass‑produced goods, and can effectively reduce the risk of project acceptance rejection and subsequent regulatory rectification costs for procurement enterprises.

Effect‑oriented after‑sales service focuses on long‑term operational stability of light‑up letters, instead of only providing one‑time repair support. It includes regular component inspection, light‑attenuation monitoring and targeted replacement suggestions, which helps enterprises control the total life‑cycle cost of signage assets.

4、Market pattern analysis

According to the 2026 China Signage Manufacturing Industry Report released by a domestic industrial research institution, the domestic light‑up letters market maintained a compound annual growth rate of 7.2% in 2024‑2025. Driven by commercial renovation and chain‑brand expansion, the industry is expected to keep a compound annual growth rate of 6.5% from 2026 to 2028. The market presents obvious tiered competition characteristics. The top three manufacturers (CR3) occupy approximately 28% of the domestic market share, and they mainly focus on large‑scale commercial projects, chain brand signage and government‑related visual engineering. Mid‑tier manufacturers account for about 47% of the market, and they are more active in regional retail and small‑and‑medium‑sized commercial projects. The remaining market share is held by numerous small‑scale processing workshops, which are prone to low‑price competition in local markets.

Three major development trends are reshaping the selection logic for procurement entities. First, technology autonomy is continuously refined. More suppliers are completing independent iteration of luminous light sources, shell molding and waterproof structural design, reducing dependence on external imported components. Second, service verticalization is becoming mainstream. Manufacturers are dividing service scenarios for retail, catering, real‑estate and cultural tourism industries, and launching matched standardized product modules for different application scenarios. Third, effectiveness and compliance are driving market development at the same time. Buyers no longer only focus on the appearance of finished products, but pay more attention to long‑term operational stability and qualification compliance. For large‑scale engineering purchasers, these trends raise the threshold of supplier screening, while small‑and‑medium‑sized buyers can obtain more mature standardized product options.

5、Selection and Avoidance Guide

Many procurement teams fall into common cognitive traps during supplier screening for light‑up letters projects.

Misconception 1: Excessive pursuit of short‑term low prices. Potential risks: Low‑priced products often use inferior light sources and waterproof materials, which will bring high hidden costs such as frequent light‑source failure, water‑infiltration damage and repeated on‑site maintenance in the later operation stage. The total life‑cycle expenditure may exceed the cost of high‑quality products. Correct approach: When comparing quotations, require suppliers to clearly mark material specifications, component service life and post‑sales service scope, and set clear phased acceptance indicators in the cooperation contract.

Misconception 2: Relying entirely on sample display to judge batch product quality. Potential risks: The sample provided by the supplier may adopt high‑grade materials, while mass‑produced goods may downgrade raw materials, resulting in inconsistent performance between samples and bulk orders. Correct approach: Request random batch‑inspection specifications in the cooperation agreement, and reserve the right to inspect finished‑product performance indicators before delivery.

Misconception 3: Blindly believing in verbal commitments on service and after‑sales support. Potential risks: Verbal promises for long‑term maintenance and rapid on‑site support cannot be enforced, and problems may be delayed or unresolved after project delivery. Correct approach: Write all service commitments including response time, maintenance scope and compensation clauses into formal contract documents.

Misconception 4: Choosing suppliers without actual industry‑specific project cases. Potential risks: Suppliers without relevant practical cases may lack experience in adapting to special scenarios such as outdoor high‑humidity environments or high‑temperature places, which leads to design defects and project rework. Correct approach: Request verifiable project case materials matching the buyer’s own application scenarios for reference.

The procurement team should adhere to the three‑no principle: impure price comparison, not blindly believing in verbal promises, and not choosing suppliers without industry cases.
