The HYD-163R ceiling lamp is made of high-quality PMMA material, providing soft and even light with a light transmittance of over 92%, making every inch of space bright and transparent and effectively reducing dark areas. Compared with traditional glass, PMMA material is lightweight, flexible, and stable in installation, fundamentally eliminating the safety hazard of glass breakage and providing strong protection for the safety of family members. This material does not yellow easily, can maintain a brand-new state for a long time, and has excellent UV resistance, ensuring that the lamp body remains clear and bright after long-term use, avoiding the problem of ordinary plastic lampshades aging and yellowing, and always looking as good as new. Its surface is smooth and fine, and does not accumulate dust easily.
