What is the standard size for fluorescent light fixture?
T8s are 1-inch diameter fluorescent tubes, and they are the most prevalent of all fluorescent tubes. Four-foot T8s, in particular, are used everywhere – in hospitals, commercial office spaces, schools, retail spaces, warehouses… everywhere.
How do I know what length fluorescent tube I need?
For length it is imperative to measure your tube to the end of the tube including the pins. Sometimes it is easier to use a tape measure than a small ruler.
Can you replace fluorescent tubes with LED?
Yes, you can replace fluorescent tubes with LED tubes or LED-integrated fixtures. If you just want to replace the bulbs, you can use plug-and-play, direct-wire, or hybrid LED tubes. Plug-and-play tubes are the easiest to install as they do not require any rewiring to the fixture.
What length are fluorescent tubes?
The smallest fluorescent tube is the T2 and it has a length of between 250mm and 760mm. The next longest tube is the T4, with a total length of anywhere between 150mm and 1,500mm. This is followed by the T5, with a length of between 340mm and 1,800mm. The length of the T8 tube may be anywhere from 600mm up to 2,400mm.
What is the difference between T8 and T5?
T5 fluorescent light bulb is a newer technology than T8. T5 fluorescent light bulb has an efficiency of about 100 lm/W. T8 fluorescent light bulb can reach about 90 lm/W luminous efficacy. In other words, T5 fluorescent lamps can use the same amount of power to produce more light.
Do you have to remove the ballast for LED lights?
An LED light does not require a ballast because it uses a component called a “driver” to regulate the power going into the bulb.
Are fluorescent tubes being phased out UK?

What does T12 mean in fluorescent bulbs?
twelve eights of an inch
The associated number represents the diameter of the lamp. This number is the numerator in a fraction where the denominator is 8 and the length is in inches. For example, with a T12, the diameter is 12/8, or twelve eights of an inch. Another way to say this is that the diameter is equal to 1.5 inches.
Are fluorescent lights being discontinued?
The Ecodesign Regulation set a schedule to eliminate integrally-ballasted compact fluorescent (CFLi) and T12 linear fluorescent (LFL) lamps in September 2021, and most T8 LFLs in September 2023.
How do I know if I have a T8 or T12 ballast?
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.
How can I tell what kind of ballast my fluorescent fixture has?
Simply turn the light on, then take a photo of the fixture using your smartphone or digital camera. If there are no dark bands on the resulting image, you have an electronic ballast that will work with direct drop-in LED tubes.
