The major physical difference between T5 and T8 light bulbs is the length and diameter of the tube itself. The T5 tends to be slightly shorter than the T8 tube, and is significantly smaller in diameter. This factor is important to consider when looking at your fixture, because the two tubes are not interchangeable.
How do I know if my ballast is 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.
Are all fluorescent tubes the same?
All fluorescent lamps use the same technology, but there are several different variations and sizes.
What is the difference between a T8 and T12 fluorescent tube?
The main difference between T8 and T12 tubes is the tube’s diameter. T12 tubes are 1.5″ in diameter while T8s are just one inch. All other things—socket sizes, lengths, distance between pins—are the same. T8 LED tubes won’t fall out if you try to install them in a T12 fixture—they’ll fit just fine.What's better T5 or T8?
The T5 has a better lumen-to-watt ratio than the T8, implying that its output is more efficient and brighter per watt of energy used.
Can I put a T8 bulb in a T12 ballast?
T8 tubes are simply 1 inch in diameter versus the 1.5 inch diameter of T12 tubes. In an effort to make LED tube lights compatible with the internal dimensions of most fixtures, you will find that most LED tube lights feature a T8 or 1 inch diameter. They can indeed be used in T12 fixtures.
What size fluorescent tube do I need?
In order to identify which size you need, the easiest way to tell is to read the label near the base of the tube. If this information is no longer legible, you can measure the bulb’s diameter. Fluorescent tubes are measured in eighths of an inch.
What is a T5 fluorescent tube?
A T5 is a type of fluorescent tube. It differs from a T12 and a T8 in its diameter. All T5s are 5/8ths of an inch (T8s are exactly 1inch thick and T12s are 12/8ths or 1.5 inches thick). T5s are 16mm in diameter making them the thinnest fluorescent tube out of the three.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.
Are T12 bulbs being discontinued?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.
Article first time published onAre fluorescent tubes being phased out?
The sale of halogen lightbulbs will be banned in the UK from September as part of ministerial efforts to cut carbon emissions. A ban on fluorescent lighting, which is mostly used in offices, will follow in September 2023.
Can I 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.

Can you use T5 bulbs in a T8 fixture?
T5 lamps cannot replace T12 or T8 lamps because of differences in physical and electrical characteristics. T5 lamps come in different lengths than T8 and T12 lamps. … Miniature bi-pin sockets fit T5 lamps, while T8 lamps need medium bi-pin sockets.
What does T8 mean?
What does “T8” mean? The “T” designation in fluorescent lamp nomenclature stands for tubular — the shape of the lamp. The number immediately follow- ing the T gives the diameter of the lamp in eighths of an inch.
Can I use a T5 ballast for T8?
In most cases, the T5 ballasts will not work with T12 or T8 lamps, although at least one manufacturer offers electronic ballasts that can operate either T5 or T8 lamps with appropriate wiring. T5 lamps operate at frequencies greater than 20 kilohertz.
What is the difference between T4 and T5 lights?
There are many types of fluorescent lights available but the main difference between the T4 and T5 lights are their efficiency or their watt consumption and lumen output, as well as the thickness of the tubes. The T4 has a half-inch diameter, while the T5 is five-eighths of an inch.
Which is better Tubelight or LED?
The efficiency of LED lights is very high. In comparison to ordinary incandescent bulbs, tube lighting has high efficiency. However, compared to LED bulbs, it is less efficient and makes it clear that LED bulbs are more efficient than tube light, and you can get yourself some of the best-LED bulbs from Jaquar.
Where do you usually use a T5 fluorescent?
T5 luminaires are usually used in new construction projects. Because T5 lamps have smaller diameters, shorter lengths, and higher luminances than T8 and T12 lamps, they are more suitable for indirect lighting, direct/indirect lighting, direct lighting for high-bay applications, and wall-washing applications.
What is the difference between T5 and T12 bulbs?
T5 tubes are smaller than T8 and T12 tubes, which allow them to fit into smaller spaces. They are offered in sizes of 2-5 feet in length. T5 lamps are around 40% smaller than T8 lamps and almost 60% smaller than T12 lamps. … 625-inch bulb diameter, and a mini bi-pin base, the T5 lamp can be used in lower profile areas.
Can I replace T8 with LED?
Type A – LED tube has an Integrated Driver for use on Existing Fluorescent Ballast. Type A LED tubes need an existing T8 electronic ballast to operate. … All you need to do is remove the existing T8 fluorescent lamp and install a new T8 LED Type A lamp.

Can you use a 2 lamp ballast for 1 lamp?
A 1 lamp rapid start (series) ballast can be hard to find, but it can be replaced with a 2 lamp instant start (parallel) ballast.
How many watts is a T12 bulb?
The typical T12 four-lamp fixture uses 172 watts of power between the lamps and ballast. LED equivalents typically use only 50 watts, 71% less energy per fixture.
What happens if you use wrong ballast?
If you use a wrong sized ballast the LRC will not be tuned so you are likely to not start the lamp at all. There is the possibility of burning out components pre-maturely also due to overcurrent and overvoltage conditions particularly if using a larger ballast on a smaller fixture.
How do you tell if it's the ballast or the bulb?
One probe of the multimeter should touch the hot wire connections, while the other touches the neutral wire connections. If the ballast is good, an analog multimeter has a needle that will sweep to the right across the measuring scale. If the ballast is bad, then the needle won’t move.
What is the disadvantage of electronic ballast?
Electronic ballasts are more efficient and more compact in size and weight. They also provide the ability for continuous power adjustment at different settings. A disadvantage is that power fluctuations may cause a failure but this can be offset by adding a buffer capacitor. Operation of the ballasts generate heat.
Which is better LED or T5?
The main advantage of LED over T5 lights is that it is more efficient, which will save cost (bulbs & power) in the long run. Designs are often more sleek. LEDs also do not produce UV light by default (unless UV diodes are used), while florescent lighting does. …
What is T12 fluorescent tubes?
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.
Which is brighter T12 or T8?
The Standard T12 lamp produces 2,650 initial lumens per lamp. The standard T8 produces 2,800 initial lumens per lamp, 6% brighter. But the standard T12 lamp produces 2,300 design lumens and the T8 produces 2,660 design lumens. … Design Lumens are the average lumen output of the lamp after 40% of its rated life.
Is G13 the same as T12?
T12 38mm (G13) Fluorescent Tubes The largest size T12 (38mm) is no longer being manufactured, however, they did use the same G13 cap as the T8 fluorescent tube which means that you can replace the T12 tubes with the more efficient T8 of the same length.
