In this factory walkthrough, we take you inside Leadray's 68,000 sqm solar lighting manufacturing base to show how solar street lights are built, tested, and deployed. You'll see SMT assembly lines, 72-hour aging tests, and IP waterproof checks, then explore real project installations — from municipal roads to rural lighting — and the integrated solar street and garden light range. A clear look at the process, quality control, and OEM/ODM support behind reliable outdoor solar lighting.
