What Are the Pros and Cons of Replacing T12 Fluorescent Lights with T8s?

The basic difference between a T8 light and a T12 light is the size of their tubes. T8 lights have a diameter of one inch, while a T12 light has a diameter of 1.5 inches. The narrower diameter of a T8 light means it is much more efficient than a T12 and can output up to 40% more energy while using less power. Though they both emit the same amount of light, a T8 light is considered to be the more energy efficient choice.

A T12 and a T8 light both use the same fixture, meaning you won’t need to invest in new fixtures if you choose to switch to a T8. Additionally, the same ballast which moderates electricity to the lamp can be used for both types of light. Therefore, the switch to a T8 light can save you money while also being environmentally friendly.

Unfortunately, there isn’t a significant difference in price between the two types of light yet. Though T8 lights are the more efficient choice, their price is still firmly in the shadow of T12 lights. Manufacturers of T12 lamps are slowly phasing them out since the technology is considered outdated. Therefore, the price gap between the two is sure to close as the production of T12s decreases.

In summary, the T8 light is the more energy efficient option when compared to the T12. Though it requires more energy to produce, it can also save you a lot of money in the long run, since less power is needed to operate it. That being said, the price of T8 lights is still higher than that of T12s, though this is sure to change as production of the latter decreases.
