Introduction ： The global lighting landscape is undergoing a massive transformation as businesses prioritize efficiency and sustainability over outdated fluorescent technologies.   In commercial, industrial, and public infrastructures, fluorescent lighting is being systematically phased out. This is not a design trend or a temporary shift in preference. It is a calculated structural change driven by crushing energy costs, rising maintenance burdens, and increasingly strict environmental regulations. For any led light fixture manufacturer , the data is clear: the era of the fluorescent tube is ending, replaced by the superior engineering of LED integrated systems. This article analyzes the economic and technical drivers behind this "silent replacement" and why integrated LED tubes have become the standard for modern facility management.   1. Energy Efficiency: The Core Reason Behind the Global Shift 1.1 Fluorescent Lighting’s Energy Ceiling For decades, fluorescent tubes were ...
