The main difference between T8 and T12 tubes is the tube’s diameter. T12 tubes are 1.5″ in diameter while T8s are just one inch. All other things—socket sizes, lengths, distance between pins—are the same. T8 LED tubes won’t fall out if you try to install them in a T12 fixture—they’ll fit just fine.
Which is better T8 or T12 bulbs?
The smaller the lamps the more energy efficient they are. T8 bulbs use about 35% less electricity to produce the same amount of light as a T12. T5 bulbs use about 45% less energy than T12s.

Are T12 lights being discontinued?
In effect since July 2012, the legislation eliminates nearly all 4-foot T12 lamps, some 4-foot T8 lamps, most 8-foot T12 lamps, and almost all standard halogen PAR38, PAR30 and PAR20 lamps from the market.

They can indeed be used in T12 fixtures.Can you put a T5 bulb in a T12 fixture?
T5 lamps cannot replace T12 or T8 lamps because of differences in physical and electrical characteristics. T5 lamps come in different lengths than T8 and T12 lamps. … Miniature bi-pin sockets fit T5 lamps, while T8 lamps need medium bi-pin sockets.
Can you replace a T12 ballast with a T8 ballast?The easiest and lowest price option to replace a T12 is a T8 linear fluorescent. They have become the go-to option for pre-existing T12s. If you still have magnetic ballasts, switching to a T8 will require a ballast swap. Another option is to move forward with an LED retrofit.

- Install ballast-bypass linear LED lamps. …
- Install plug-and-play magnetic and electronic ballast-compatible linear LEDs. …
- Install electronic ballast-compatible linear LEDs and a new electronic ballast.
What is the use of electronic ballast?
An electronic ballast (or electrical ballast) is a device that controls the starting voltage and the operating currents of lighting devices. It does this through the principle of electrical gas discharge.
Do I need to remove ballast for LED lights?
A plug and play LED is a fixture where you can install LED bulbs to what was once a fluorescent bulb. This is an easy solution and requires minimal effort on your part. Since it works with the existing ballast, there is no need for rewiring or ballast removal.
