T8 & T12 Compared

T8 and T12 both feature the same G13 bi-pin connector, FA8 R17D. The T8 tubes are slightly smaller at 1 inch in diameter, compared to the 1.5 inch diameter of T12 tubes. The T12 fixtures tended to use magnetic ballasts. T8 fluorescent bulbs are just as bright as the T12 – and much more economical. The T8 models cost almost half of the T12. If the room has less than 12 feet of height, a T8 can illuminate the space adequately. Color characteristics in T8s have improved dramatically so that the standard T12 with its larger tubes has become obsolete.

How to Install a T8 in a T12 Fixture

The energy-efficient T8 lamps give a boost of lighting to any space. Convert a T12 fixture into the energy-saving T8 with a retrofit conversion kit. Turn off the power going to the fixture at the circuit breaker. Locate the ballast cover and pry it from inside the fixture by removing the screws or tabs. With wire cutters, remove the wires from the old ballast and remove the nut or screw that secures the ballast. A hot wire is usually covered in black and red, while a neutral wire is white. The white wire completes the circuit back to the electrical panel. Place the T8 ballast in the old fixture and secure the nuts and screws. If you discover a magnetic ballast, a separate starter device needs to be found and disconnected.

FAQ:

Are T12 fluorescent bulbs being phased out?

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. T12 technology is over 80 years old. Since that time, lamps and bulbs have been developed that just work better.

What does T8 mean on a light bulb?

A T8 lamp (on the right in the figure below) is eight-eighths of an inch, or one inch (2.54 cm), in diameter. Both T12 and T8 lamps use the medium bi-pin base, which allows T8 lamps to fit into the same luminaires as T12 lamps of the same length.
