T5 lamps have a diameter equal to 5 times an eighth of an inch, or 5/8". These lamps are approximately 40% smaller than T8 lamps, which are one inch in diameter, and almost 60% smaller than T12 lamps, which are 1½" in diameter. Figure 1 shows diagrams of lamp ends of T5, T8, and T12 lamps.Also, what is the difference between t8 and t5 lights?
What are the Main Physical Differences Between a T5 and a T8 Lamp? T5 lamps have a diameter of 5/8” compared to 1” diameter of T8 lamps. T5 lamps are available only in metric lengths (and are generally shorter than equivalent T8). T5 lamps utilize a mini-bipin base while T8 lamps use a medium bipin base.
Also, are t5 and t8 bulbs interchangeable? T5 and T8 lamps have different diameters so they are not usually interchangeable.
