The size of a fluorescent lamp

What is "T"?

The "T" is simply a code that is used to determine the size of a fluorescent lamp. As a focus on energy saving technology has developed into a universal, these codes are to specify the energy efficiency rating, as well as the tube diameter.

T5 does not cost nearly 2 times more, but the same margin can not be applied to performance. Ben T5 was not the same as to outperform T8. In fact, the difference in performance is negligible in many low level applications.

Both T5 and T8 lamps have a general life expectancy of about 36000 hours. At 12 hours. Burning time per day.
