I'm looking for a tubular bulb for my fixture, and I see "T8," "T5," and "T12" listed. What do these "T" numbers mean, and how do they differ?

The "T" in these codes indicates a tubular shape, often used for fluorescent or LED tubes, and the number represents the tube diameter in eighths of an inch; thus, a <a href="https://www.homedepot.com/b/Lighting-Light-Bulbs/T8/N-5yc1vZbmbuZ1z0vvri?emt=plpfaq_2504_lightbulbs" style="text-decoration: underline;">T8 bulb</a> is 1 inch in diameter, while a <a href="https://www.homedepot.com/b/Lighting-Light-Bulbs/T5/N-5yc1vZbmbuZ1z0vvq7?emt=plpfaq_2504_lightbulbs" style="text-decoration: underline;">T5 bulb</a> is 5/8 of an inch, and a <a href="https://www.homedepot.com/b/Lighting-Light-Bulbs/T12/N-5yc1vZbmbuZ1z0vvrc?emt=plpfaq_2504_lightbulbs" style="text-decoration: underline;">T12</a> is 12/8 of an inch (or 1.5 inches), with the smaller diameter often correlating to newer, more energy-efficient models. Choose the correct number that matches the socket in your fixture.
