Worried about product quality and questioning the actual effect

We have launched a “two-way guarantee” service: first, we provide free sample trials, so that customers can first test the core indicators of the lamps such as brightness, color rendering, and energy saving, and then purchase in bulk if they are satisfied; second, we issue authoritative test reports (such as CE, ROHS, and national energy efficiency certification) and promise “3-year warranty, free replacement for non-human damage”. At the same time, we open a factory tour channel for customers to view the production process and quality control standards on site, so as to dispel quality concerns.
