What are the standard lengths of fluorescent tubes?
Common tube ratings
| Tube diameter in 1⁄8 in (3.175 mm) | Nominal length | Nominal power (W) |
|---|---|---|
| T8 | 4 ft (1,219 mm) | 36 |
| T8 | 5 ft (1,524 mm) | 58 |
| T8 | 6 ft (1,829 mm) | 70 |

How do I know what size fluorescent bulb I need?
First, you will need the diameter or how wide it is around. This is expressed as a number such as T8 or T12. The “T” stands for tubular, and the number is a measurement of the diameter in 1/8″ increments. So a bulb with a 1″ diameter would be a T8—eight 1/8″ increments.
What are the long tubular bulbs called?
fluorescent lamp
A fluorescent lamp, or fluorescent tube, is a low-pressure mercury-vapor gas-discharge lamp that uses fluorescence to produce visible light.
What is the most common light bulb size?
An E26 is the most common base size used in the manufacturing of incandescent, CFL, LED, and halogen light bulbs. The “E” stands for Edison and “26” means the base diameter measures 26 millimeters across.
Can I replace a T12 bulb with a T8?
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.
What length do fluorescent light bulbs come in?
Fluorescent circline tubes are typically 1 and 1/8 of an inch in diameter. Their outside diameter (which is measuring the circle from one end to the other) comes in four options – 6, 8, 12, and 16 inches.
How do I know if I have T8 or T12?
If no markings are available, the size in diameter of the tube is the easiest way to determine the type you have installed. T8 tubes are 1-inch in diameter and T12 tubes are 1 1/2 -inch.
What are long fluorescent lights called?
Linear fluorescent tubes. Linear fluorescent tubes are the most common type of fluorescent lamps.
What is the brightest 4 foot fluorescent bulb?
The brightest four foot T8-sized LED tube light is the Barrina LED Shop Light Fixture. This tube shines with 5000 lumens using 44 watts. It replaces a 72 watt fluorescent tube.
Is A15 the same as E26?
There’s a “bulb size” and a “base size.” The bulb size is self explanatory. The A15’s are smaller bulbs, while the A19’s are larger. They both fit in a standard household medium base (E26 base.)
What are the different sizes of fluorescent light bulbs?
What are Standard Fluorescent Bulb Sizes? 1 T5 Fluorescent Tubes. T5 fluorescent tubes are used to light retail stores, schools, office buildings, workspaces, and more because of their illuminating characteristics. 2 T8 Fluorescent Tubes. 3 T12 Fluorescent Tubes. 4 Circular Fluorescent Tubes.
What do the numbers on fluorescent tubes mean?
There are 4 different fluorescent light options; T4, T5, T8, and T12. The T stands for tubular and the numbers are an index for the diameter (in inches) of the tube. Most tube lighting will have its size mentioned on an end of the tube.
What is the most common type of fluorescent tube?
A tube with two pins on either end is the most common type of fluorescent lamp. The tube’s diameter is measured in eighths of an inch, just like incandescent lamps. (Read Light Bulb Sizes Chart)
How do I know which fluorescent light bulb to buy?
When considering the question of how do I know which fluorescent light bulb to buy you need to figure out what you currently have. Once you have removed the bulb most will be marked with the type on the end, if there are no markings then you can measure the tube diameter to determine their type.
