TL84

TL84 is a designation used in various industries to label specific product variants, most commonly in lighting. In the context of fluorescent lighting, TL84 refers to a compact fluorescent lamp (CFL) in the TL family, a line of four-pin plug-in lamps designed to be more energy efficient than conventional incandescent bulbs.

Construction and operation: TL84 lamps usually consist of one or more small fluorescent tubes mounted on a compact base. They require a compatible ballast or electronic driver to operate from standard AC mains. They are installed in fixtures that support CFLs with the same base and wattage rating, and they are commonly used in offices, retail spaces, and residential luminaires.

Variants and specifications: Because the TL84 designation is used by multiple manufacturers, exact electrical specifications (wattage, color temperature, CRI, base type) can vary widely between models. Typical color temperatures range from warm white to cool white, and lifespans are longer than incandescent lamps but depend on usage and ballast quality.

Other uses: Beyond lighting, TL84 has been used as a product code or model number in other industries, including electronics and consumer goods, where the meaning is determined by the specific manufacturer.
