ABOUT SENFEY
Your Engineering LED Partner in Shenzhen
More than a manufacturer — Senfey is a complete LED lighting system provider for engineering and architectural projects worldwide.
Engineering Capability, Not Just Manufacturing
Senfey Lighting Technology Co., Ltd. has grown from a LED strip manufacturer into a full-system engineering LED solution provider. Based in Shenzhen, China, we operate a 5,000 sqm production facility with 6 automated SMT lines and a dedicated R&D center.
What sets us apart is our system-level approach. While most LED strip factories sell individual components, Senfey configures, tests, and delivers complete LED lighting systems — strips, profiles, power supplies, controllers, and accessories — all verified to work together for your specific project.
“Our engineering team includes lighting designers, electrical engineers, and project managers who understand the requirements of large-scale architectural and commercial lighting projects. We speak the language of contractors, lighting designers, and project developers.”
