Can I replace T12 with T8?
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.Aug 19, 2016
What is difference between T8 and T12 lights?
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.May 16, 2019
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.Feb 1, 2010
Can I use a T8 LED tube in a T8 fluorescent fixture?
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. If you have T8 electronic ballasts this makes installation very easy. All you need to do is remove the existing T8 fluorescent lamp and install a new T8 LED Type A lamp ...
Are T8 fluorescent bulbs being discontinued?
Even some T8 lamps have been phased out. US Congress has enacted legislation to prohibit the manufacture of these and other inefficient lighting technologies, and is calling for manufacturers to meet minimum efficiency requirements and lumens per watt for new products.
Why are T8 more efficient than T12?
T8 lamps are fluorescent lights one inch (or 8/8ths) in diameter. T5 lamps are 5/8th in diameter. 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.Oct 9, 2015
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.
What's better T5 or T8?
The T5 has a higher lumen to watt ratio than the T8, which means its output is more powerful and brighter per watt of energy. The T5 is also more efficient because its light concentrates in a single spot because of its smaller diameter–– more watts per cubic centimeter.Feb 10, 2022
How big is a T8 lamp?
This means that the T8 has a diameter of eight eights of one inch , and the T12 has a diameter of twelve eights of one inch. Typically, the efficiency of a lamp can be determined by its size, and the smaller the lamp, the bigger the efficiency.
How many watts does a T8 bulb use?
And when it comes to energy usage, the T8 bulb is 32 watts, while the T12 bulb is 40 watts. This clearly means that the T8 is a more efficient light bulb to use and due to a federal act, a lot of buildings have to use the T8 bulb instead of the T12 preferably due to energetic efficiency.
How long does it take for a light bulb to stop working?
The bulbs tend to start decreasing their light output after around 7,000 hours of usage and even though that sounds like a lot, it is not an eternity (unfortunately). After that period of time, they start to lose quality, but most people only replace their light bulbs when they really stop working.
Why is T8 switching to T12?
Probably the most important reason why it's time to move over to T8 from T12 lighting is due to regulatory changes. Like it or not, T12 ballasts and bulbs are being regulated out of the picture. It's only a matter of time before we need to make changes.
How many watts does a T8 light use?
This characteristic, together with good engineering, allows for T8 lamps to run with more energy efficiency. T8 lamps run on 32 watts as compared with 40 watts for T12 lamps.
Is a T8 bulb brighter than a T12 bulb?
While T8 fluorescent bulbs run on less energy, it does not mean that they are less bright. In fact, studies have shown that they are slightly brighter than T12 bulbs. T8 bulbs were originally designed to shine just as brightly as T12 bulbs. In practice, this is found to be the case and even better. In one study, T8 was found to run at 2600 lumens, vs a sub-2600 level for the T12 bulb.
