1. Core International Standards for Glass Lamp Shade Fittings<\/h2>
\u00a0<\/div>
Global lighting manufacturers follow standardized fitting dimensions to ensure universal compatibility across regions. The most widely adopted standards are defined by IEC (International Electrotechnical Commission)<\/strong> and regional bodies like UL (US), CE (EU), and AS\/NZS (Australia\/New Zealand), with core common dimensions for glass shade mounts:<\/div>
