As far as safety is concerned, you can exchange them. If you place T12 tubes in a fixture with a T8 ballast, you will wear out the ballast and have to replace it. If you place T8 tubes in a fixture with a T12 ballast, then the tubes will have a shorter life due to a higher current through the tube.
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.
Which bulb is brighter T8 or T12?
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.
Are T8 and T12 pins the same?
As we describe in our how to article, T8 and T12 feature the same G13 bi-pin connector. T8 tubes are simply 1 inch in diameter versus the 1.5 inch diameter of T12 tubes.What happens if you use a T8 bulb in a T12 fixture?
T8 LED lamps which are not direct-wire compatible (with ballast) will require a T8 ballast to operate, so unless the T12 ballast in the T12 fixture is replaced with a T8 ballast, a non-direct-wire compatible T8 LED lamp will not work in a T12 fixture.
Do T8 and T12 bulbs use the same socket?
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 is better T12 or T8?
The smaller the lamps the more energy efficient they are. T8 bulbs use about 35% less electricity to produce the same amount of light as a T12. … For some applications, one T5 bulb can replace two T12 bulbs, providing even greater energy savings (a process called “de-lamping.”)
What's better T5 or T8?
T5 lamps are smaller and more efficient than T8 bulbs. T5 lights are the winner between the two, they do cost about 2x more than T8 options. While T8s are cheaper upfront, T5s are a more affordable option long-term and are great for most growing needs.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.
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.
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.
What's the brightest fluorescent light?
Fluorescent T5s T5s are fluorescent tubes that are 5/8 of an inch in diameter. These are the newest development in the fluorescent family. Although they are the smallest, they are the most energy efficient and brightest.
How do I know what size fluorescent tube 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.
Is F40 same as T12?
This is calculated in 1/8″ increments. This means a T8 lamp is 8/8ths of an inch in diameter, or 1 inch. A T12 is 12/8ths of an inch, or 1.5″ in diameter. … All F32 and F40 lamps are essentially 4 foot long lamps (47″ if you don’t count the pins).
Are T12 sockets shunted?

Can you put LED lights in a fluorescent fixture?
Many LED tubes are “plug and play”, meaning you can just install them like you would a fluorescent bulb. For this to be true, look for bulbs that are “ballast-compatible” meaning that they can use the ballast already installed in your fluorescent fixture to power the LEDs.
Can you replace old fluorescent tubes with LEDs?
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.
What does T8 fluorescent mean?

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.
How long do T12 bulbs last?
Typical lamp life for a fluorescent bulb is about 20,000 hours, but this can degrade as a consequence of frequent switching (turning on and off). Burning life is extended if lamps remain on continuously for long periods of time.
Can I use a T5 bulb in a T8 fixture?
T5 lamps cannot replace T12 or T8 lamps because of differences in physical and electrical characteristics. … Miniature bi-pin sockets fit T5 lamps, while T8 lamps need medium bi-pin sockets.
Are T8 LED bulbs worth it?
They are not only more efficient than all other forms of commercially available lighting. They are far more efficient than all other forms, and that racks up over time. You could save a lot of money on energy by replacing your fluorescent bulbs with LEDs.
Can you mix LED and fluorescent tubes?
Yes, and there are advantages in mixing them. The LEDs comes on instantly, whereas the CFLs can take longer, so a mixture is faster acting than only CFLs. Even though CFLs don’t come up to full brightness instantly, their slow speed is much less noticeable with an LED or two in the mix.
