Plug-In Long FTL Lamps are energy-efficient fluorescent tubes with a plug-in base, commonly used in commercial and industrial lighting. They feature a longer tube design and typically use a G24Q or similar base, allowing for easy installation in compatible fixtures without the need for an external ballast. These lamps offer long lifespan, low energy consumption, and are often used in offices, retail spaces, and other environments that require bright, efficient lighting.
