You can determine whether your fluorescent bulbs are T8 or T12 by checking the label printed on the tube, which usually lists the bulb type. If the label isn’t visible, measure the bulb’s diameter: T8 bulbs are about 1 inch (2.54 cm) across, while T12 bulbs are about 1.5 inches (3.8 cm). Knowing your bulb type is important for selecting compatible LED replacement tubes and ensuring proper fixture performance.
