Fluorescent Tube Size and Wattage Guide
The number after T is the diameter of the tube in eighths of an inch. Other common sizes are T12 bulbs with a 1.5 in. diameter or the T5 with 5/8 in. diameter. The fastest way to know the size and wattage of your current bulb is to check the label on the end, but measuring the diameter works if this label is illegible. The F signifies that the tube is a fluorescent as opposed to an LED and the number after F tells you the wattage. If you’re looking for a 32-watt fluorescent tube, click the F32T8 category.
