There are several types of fluorescent lights.
What is a t8 lamp.
On the most basic level the t12 and the t8 bulbs have a different diameter tube thickness.
Figure 1 shows the range of values for rated initial light output that are presently published for 121 lamp models by nine manufacturers for different correlated color temperatures cct.
Many years ago the research found out that if they could make the light tube thinner then there would also be greater energy efficiency associated with it.
The t12 is 1 5 inches in diameter and the t8 is 1 inch in diameter.
Lamps are typically identified by a code such as fxxty where f is for fluorescent the first number xx indicates either the power in watts or length in inches the t indicates that the shape of the bulb is tubular and the last number y is the diameter in eighths of an inch sometimes in millimeters rounded up to the nearest millimeter.
T8 fluorescent lamps are available with a variety of rated light output values.
T8 lights are a good choice for an adjustable lighting system because of their color temperature range from a soft yellow white to bright daylight.
The most common straight tube types are t5 t8 and t12 available in lengths up to eight feet.
Fluorescent tube lights use low pressure mercury vapor gas and after a large amount of electricity is applied to the tube it creates an electric arc of power that energizes the mercury vapor.
The other common lamps are the larger t8 eight eighths inch 1 and t12 twelve eights inch 1 tubes.
The amount of light generated by 32 watt t8 fluorescent lamps varies considerably from one lamp model to the next and from one manufacturer to another.

It can have a bi pin or single pin base that plugs in to the sockets of a fixture.
A t8 light bulb is a linear tube with 1 inch 2 54 cm diameter.
Limited testing by nlpip found differences between rated and measured light output values.
The t12 is an older generation fluorescent bulb that generates light through electromagnetic induction which is considered less efficient method of creating light compared to that of newer electronic based circuits.
Commercial electric 32 watt.
All fluorescent bulbs require a ballast to operate while older models require a starter as well.
This type of fluorescent tube lighting is the most popular because of its high cri and many color temperature options.
