Do you know what a T8 bulb is?
Fluorescent tube size and wattage guide
T8 filament bulbs are 8/8ths of an inch or 1 inch in diameter. Other common sizes are T12 bulbs, which are twelve-eighths of an inch or 1.5 inches in diameter, and the T5 bulbs, which are five-eighths of an inch or . 625 inches in diameter.
Additionally, how long is a T8 fluorescent lamp?
Length varies for each lamp size, standard T8s come in 2ft, 3ft, 4ft, 5ft available and 6ft; Standard T12s are available in 2ft, 4ft, 5ft, 6ft and 8ft. Standard T5 bulbs are smaller and come in 6, 9, 12 and 21 inches.

5 different types of light bulbs
- Incandescent lamps: Incandescent lamps are the typical light bulbs.
- Fluorescent lamps: Fluorescent lamps are more complex than incandescent lamps.
- Compact Fluorescent Lamps (CFL):
- Halogen lamps :
- Light Emitting Diode (LED):
Do t8 and T12 bulbs use the same socket?
T12 will mainly operated by magnetic ballasts and T8 filament lamps are operated e on electronic ballasts. Even if the fluorescent lamp holder is exactly the same for both, they cannot be operated with the same ballast.
What types of fluorescent lamps are there?
The two most common types are 40 watt, 4 foot (1.2 meter) lamps and 75 watt, 8 foot (2.4 meter) lamps. Now tubular fluorescent technology has improved.
How many lumens does a T8 have?
As the data in Figure 1 shows, T8 lamp models with light output values of almost all are 50 lumen Steps between 2800 lumens and 3200 lumens.
What happens when you put a T8 bulb in a T12 fixture?
You need to remove the ballast – like most T8 bulbs Tubes have an electronic inside. If you use them in t12- you will burn the bulb and they will work sporadically before dying. The luminaire is also blackened.
How do T8 light bulbs work?
Fluorescent lamps work by ionizing mercury vapor in a glass tube. This causes electrons in the gas to emit photons at UV frequencies. The UV light is converted to normal visible light using a phosphor coating on the inside of the tube.
How do I know if a ballast is bad?
If your fluorescent lighting shows If one If any of the following occurs, this could be a symptom of a bad ballast:
- Flickering.
- Humming.
- Delayed start.
- Low Performance.
- Inconsistent lighting levels.

- Switch to an electronic ballast, switch to a T8 – Fluorescent tube.
Are all T8 lamps the same?
A T8 lamp (on the right in the image below) is eight eighths of an inch or one inches (2.54 cm) in diameter. Both T12 and T8 bulbs use the medium sized twin pin base, which allows T8 bulbs to fit in the same fixtures as T12 bulbs of the same length.

The number next to the T indicates the diameter of the fluorescent tube. Since the measurements are in eight inches, the T8 is one inch in diameter, while a T12 is 1.5 inches in diameter. The narrower your choice of fluorescent lamps, the more efficient their energy output.
Do I need to remove the ballast to use an LED lamp?
LED technology does not require a ballast, to regulate the amount of energy going to the lights. In addition, removing the ballast reduces energy consumption and even results in large cost savings as the ballasts continue to consume more power than necessary.
