In cold chain logistics, temperature control is a critical factor that determines cargo quality.

Based on its outstanding technology and industry trust, Qlight has signed a supply contract worth approximately CNY 2 million with global clients in Europe and North America for signal towers with built-in buzzers. These products are deployed in the clients’ smart refrigerated container projects, acting as invisible guardians throughout cold chain transport operations.

❶ Background of the Partnership

In refrigerated container transportation, there have been cases where delayed temperature alerts or device failures under extreme weather conditions caused major issues. This called for warning light solutions that not only offer precise temperature alerting but also operate reliably under harsh environments.

Qlight’s QAD100BZ model has passed rigorous vibration and shock tests, as well as high/low temperature cycling tests from -30°C to 50°C. Its design is optimized for maritime transport, offering superior resistance to vibration. It functions stably even with ship movements and meets photometric distribution and luminous intensity standards, delivering trustworthy performance across global shipping routes.

❷ Project Outcome: Secure Transport with a Smart Warning System

The smart refrigerated container project requires a system that detects internal temperature in real-time and activates both audible and visual alarms within three seconds of detecting anomalies. Qlight’s product features corrosion resistance for saline environments and IP65-rated waterproof/dustproof protection, ensuring reliable operation in humid, salty, and windy marine conditions. Additionally, its low-power design is fully compatible with container power systems, contributing to efficient logistics operations.

❸ Continuous Evolution and Customer Trust

The client provided the following positive feedback:

“Qlight’s products have a lower failure rate than the industry average, and their quick response significantly helped reduce transport losses.”

The importance of on-time delivery was also emphasized. Qlight has recognized this as a core priority and operates a customized supply chain system tailored to the client’s needs. Every large-scale delivery reaffirms Qlight’s commitment to "the highest level of reliability," and each warning light plays a crucial role in protecting industrial safety. Qlight will continue to safeguard the cold chain with light.
