Lighting &
LED

A diffuser cover is judged in three places: the extrusion line where the profile comes off at a steady wall thickness, the light box where transmittance and diffusion are measured, and the compliance file where RoHS and CE paperwork decides whether the shipment clears. These workshops extrude and assemble LED lighting components in the Foshan lighting belt — Danzao and the Nanhai cluster have supplied fixture makers for decades. Because the part sits inside a certified fixture, the paperwork follows the plastic: ask for the material grade, the RoHS / REACH reports, the photometric data and the CE file for the fixture family the part will join — a clear sample means little if the compound changes between batches.
