What is T8 vs T12?
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.Can you replace T12 with 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.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 T8 better than T12?
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. DEFINITIONS: Initial lumens – the average lumen output of the lamp after 100 hours of operation under controlled lab conditions.Can I use T8 bulbs with a T12 ballast?
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.#399: T12 vs T8 vs T5 vs LED Lights - Tank Tip
Can I replace my T12 bulbs with LED?
Can you actually retrofit T12 to LED without changing out the ballast? Actually, yes. But before you make a decision, there are other LED solutions to consider for a high-efficiency lighting option for existing T12s. A lot has changed in just a few years in the lighting industry.Are T8 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.Can you put a LED bulb in a fluorescent fixture?
You have fluorescent tube lights in your home or business already, and you're wondering if you can pop LED tubes in these fixtures or if you'll need to change out the fixtures for something designed for LED. Good news! You can use LED tubes in your existing fixtures!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 ...Do T8 LED bulbs need a ballast?
Most T8 LED bulbs do not need a ballast. The only type of LED tube that requires a ballast is plug-and-play. Used as direct replacements for fluorescent tubes, plug-and-play LED tube lights install without fixture rewiring, and operate off the existing fluorescent ballast.Do I need to remove 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.How do I know if my bulb is a T8?
If you do not see markings, the size or diameter of the tube will be the easiest way to tell the kind that you have installed. T8 tubes will be one inch in diam. and T12 will be 1 1/2 inch in diameter. If you happen to have a tube that is relatively small in diameter, about 5/8 of an inch, it is a T5.Are fluorescent tubes being discontinued?
Notes to editorsThe new regulations would phase out most remaining halogen lamps from September 2021 and the traditional fluorescent tube lighting, which are common in offices, from September 2023 onwards. HL R7 halogens will remain available on the market, and some fluorescents such as T5s.
How do I know if my ballast is compatible with LED?
You can determine whether you have a compatible fixture in seconds. 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.Do LED fluorescent lights need a ballast?
No LED bulbs require a ballast, although some are engineered to work with an existing ballast. You will find ballast-compatible or "plug-and-play" LEDs that are designed to replace linear fluorescents, compact fluorescents, or HIDs. Incandescent and halogen lamps do not require a ballast.Can I use T8 LED in T12 fixture?
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.Which light bulbs are being phased out?
The following light bulbs cannot be placed on the market* after 1st October 2021:
- Compact Fluorescent Helix Light Bulbs.
- Halogen Linear R7s Lightbulbs (over 2,700 lumens)
- 12V Halogen Spotlight Bulbs (MR11, MR16)
- Lower performing LED lamps.
Can you mix LED and fluorescent tubes?
LED and fluorescent lights on the same circuit? Some things were never meant to work together. If you intend to upgrade some lights to LED, ensure that there are no old technology lights remaining on the same circuit. LED drivers contain electronics that may be upset by old technology transformers on the same circuit.Why do fluorescent lights flicker when turned on?
When the light switch is flipped on, the starter sends out a shot of electricity to the gas inside the fluorescent tube. That gas is then ionized and can conduct the electricity necessary to run the bulb. But there's a slight delay in this process, so the bulbs flicker a bit before they turn on completely.Do T8 and T12 bulbs use the same socket?
T12 vs T8 Fluorescent TubesT12 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.
Are all T8 bulbs LED?
LED Linear Tube Options. There are three primary types of LED T8s on the market suitable for retrofits and one type that is a combination of two types. Primarily they are differentiated by how they interact with existing fluorescent ballasts. All fluorescent tubes need ballasts to operate, but not all LEDs do.What happens if you don't bypass the ballast for LED lights?
The most significant negative to a ballast-bypass linear LED is the risk of electric shock since the sockets carry line voltage. It's a common practice to place a finger on the lamp pins while you are trying to install it, and this becomes a risky endeavor when using single-ended ballast-bypass lamps .Do LED Fluorescent lights need a starter?
LED tubes do not need to have a starter (fuse) and can be fixed to be used without ballast. LED tubes are mostly used for home offices, garages and storage spaces at home.
