Traditional lighting‑energy‑efficiency assessments have relied excessively on the “luminous efficacy of the light source (lm/W)” metric, giving rise to resource waste, energy‑efficiency inversions, and widespread light pollution under a “luminous‑efficacy‑only” paradigm. Drawing on the “adapted luminous efficacy” theory, this paper systematically examines six cognitive fallacies underlying the industry’s prevailing assumption that “higher luminous efficacy always means greater energy efficiency”—namely, logical misalignment, faulty attribution, variable mismatch, blurred standards, reversed causality, and treating symptoms rather than root causes. By integrating cutting‑edge international metrics and best practices in light‑pollution prevention, the paper proposes replacing luminous efficacy with “normalized power density (NPD)” as the core indicator for evaluating lighting energy efficiency, and substituting “scene‑specific adaptation” for “extreme‑parameter benchmarks” as the benchmark for assessing lighting quality, thereby providing both theoretical foundations and practical pathways for improving energy‑efficiency assessment and mitigating light pollution.
China’s domestic Micro-LED automotive supply chain is transitioning from “fragmented competition” to “systemic collaboration.”

Introduction: In market inspections of the lighting industry, substandard luminaires repeatedly make headlines. Many people wonder: Is the CCC mandatory certification for lighting products really that technically challenging to achieve? With a surge in non‑compliant decorative lamps and custom‑engineered solutions, cases of certificate‑cloning, falsified certifications, and counterfeit certificates are cropping up with alarming frequency—what’s the underlying logic behind this trend? For distributors, simply claiming “the goods were manufactured by the factory” is no longer sufficient to avoid liability; once caught in such pitfalls, administrative penalties and civil damages can follow swiftly. This article delves into the realities of the industry and offers channel operators a practical, actionable compliance framework.
Latest financial report: In the first half of 2026, Lite-On Technology posted revenue of RMB 3.068 billion and net profit attributable to shareholders of RMB 69.79 million, marking year-on-year growth in both revenue and net profit. Amid a challenging economic environment, how has Lite-On managed to maintain its core business while achieving double-digit growth in both operating revenue and total profit?
According to the latest import and export data released by the General Administration of Customs, in the first seven months of 2026, China’s total exports of lighting products amounted to approximately US$28.7 billion, down about 6% year-on-year, accounting for 1.8% of the country’s total electromechanical product exports. In July alone, exports totaled roughly US$4.6 billion, up about 3% compared with the same month last year.
