Foshan Qiliang Optoelectronics Co., Ltd. has specialized in stage lighting for 12 years. We are a professional manufacturer supplying equipment and delivering integrated solutions for multi-function hall lighting projects, school auditoriums and studio lighting engineering projects. Supported by our self-owned factory, mature product lines and comprehensive supporting services, we provide full-process tendering assistance for contractors nationwide undertaking lighting engineering projects. Our differentiated product strengths and reliable after-sales system have won long-term recognition across numerous lighting project collaborations.

I. 12 Years of Industry Experience with High-Performance Products for All Lighting Engineering Projects

With a 12-year focus on stage lighting fixtures, Qiliang Optoelectronics（QL ProLighting） boasts abundant on-site project experience unmatched by many peers, enabling us to accurately meet lighting layout requirements for multi-function hall projects of all sizes and medium & small-scale film & TV lighting projects.

All our film and television lighting fixtures feature high color rendering with CRI ≥95 and come standard with high-output redundant power supplies. Our spotlights deliver 30% higher brightness than comparable products of the same wattage on the market. The durability of our lights has been fully proven by real-world applications: our 230W moving head lights deployed in engineering projects years ago only required bulb replacement after seven to eight years of continuous operation, with extremely low failure rates.

We have developed exclusive bid-winning lighting products tailored for multi-function hall projects, including stage spotlights, profile lights, studio panel lights and intelligent followspot systems. Our intelligent followspot devices can be retrofitted onto standard moving head lights to replace manual followspot operators, drastically cutting long-term labor costs for lighting projects. Customization is available for fixture appearance, power and color temperature to satisfy unique lighting demands of custom engineering projects. All products hold CE and RoHS certifications plus multiple independent patents, with complete qualification documents ready for tender submission.

II. Full In-House Production Chain to Guarantee Stable Delivery for Lighting Projects

Qiliang Optoelectronics（QL ProLighting） purchased a self-owned factory covering over 1,500 square meters in 2023 and completed relocation from Guangzhou to Foshan in 2025, equipped with a professional lighting exhibition hall. Our sufficient production capacity accepts rush orders for multi-function hall projects to reliably meet delivery schedules for lighting engineering works.

The company holds independent import and export rights and has long provided OEM manufacturing for domestic and overseas brands. Standardized production strictly eliminates the common industry issue of inflated power ratings; all fixtures feature genuine labeled parameters to avoid parameter mismatches during project acceptance. For school auditoriums and corporate multi-function hall projects, we offer complete lighting scheme design and on-site installation guidance, providing full tracking from pre-project site survey to final delivery.

III. Full-Cycle Pre-Sales & After-Sales Support to Help Clients Win Lighting Tenders

Tendering support is our core competitive advantage for multi-function hall lighting projects. We can supply full sets of qualification certificates, product test reports, patent documents and other tender materials on demand to help clients efficiently compile bidding documents for lighting projects. Pre-sales services include sample requests and on-site light demonstrations in our exhibition hall to intuitively display lighting effects. Standard orders ship within 5–7 working days to keep construction schedules on track.

Our after-sales policy covers a one-year full fixture warranty with a 24-hour rapid response system, combining remote troubleshooting guidance and direct spare parts delivery to reduce post-project maintenance burdens. Unlike low-cost, low-quality suppliers in the industry, Qiliang Optoelectronics（QL ProLighting） prioritizes product quality. Backed by repeat orders from decade-long clients, we consistently deliver dependable, complete lighting solutions for multi-function halls and large-scale film & TV lighting projects.

From pre-bidding coordination and customized product manufacturing to post-delivery maintenance support, Foshan Qiliang Optoelectronics（QL ProLighting） has focused exclusively on film and television lighting engineering projects for 12 years. With our self-owned manufacturing plant, high-spec bid-winning lighting products and one-stop tendering support services, we stand as a trusted long-term manufacturing partner for contractors undertaking multi-function hall lighting projects.
