T5 Fluorescent

T5 fluorescent refers to a specific type of energy-efficient lighting tube commonly used in commercial and residential settings. The "T" indicates the tube's diameter, with T5 being 5/8 inch wide. These bulbs contain a small amount of mercury vapor and phosphor coating inside. When electricity flows through, it excites the mercury vapor, producing ultraviolet light that causes the phosphor to glow, emitting visible light. T5 fluorescents are known for their high efficiency, brighter light output, and longer lifespan compared to older fluorescent types, making them a popular choice for modern lighting solutions.
