A T8 tube light is a 1 inch diameter fluorescent or LED tube of varying lengths with a bi-pin or single pin base. T8 tube lights are commonly used in high bay fixtures, troffers, and other general lighting applications. Can a T8 LED replace a T12? Yes, a T8 can replace a T12 bulb of the same length and wattage.
What is the difference between T5 and T8 LED tubes?
T5 lamps are 40% smaller than T8 fixtures, but are capable of containing just as much and sometimes more light in a smaller area. In other words, more T8 fixtures are needed to produced the same amount of light generated by significantly fewer high output T5 bulbs.
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 …
What is a T8 tube?
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. … A T8 lamp (on the right in the figure below) is eight-eighths of an inch, or one inch (2.54 cm), in diameter.
What is the difference between T8 and T12 LED tubes?
The have small pins on each end that fit into the ballasts located in light fixtures. T12 lamps have a diameter of 1 ½ inches (or 12/8th of an inch.) T8 lamps are fluorescent lights one inch (or 8/8ths) in diameter. T5 lamps are 5/8th in diameter.
Do you need starters for LED tubes?
Standard fluorescent tubes have a pre-heat starter which is not required for LED light sources. When replacing standard fluorescent tubes with LED tubes change the starter for this LED version to protect the LED tube from overload.
Is T5 better than LED?
LEDs also offer increased light efficiency when dimmed as opposed to T5 fixtures and usually produce more lumens per watt in general, which decreases energy usage and thus, energy costs. A lower wattage of LED luminaire will usually be just as efficient, sometimes more, as a higher wattage T5 lamp.
Do I need to remove ballast for LED lights?
LED technology does not require a ballast to regulate the amount of energy flowing to the lights. LED’s require less energy and can be sensitive to excess energy. … Additionally, removing the ballast will reduce energy usage and result in even great cost-savings as ballasts continue to draw more power than necessary.
Do T8 LED bulbs need a ballast?
Most T8 LED bulbs do not need a ballast. The only type of LED tube that does require a ballast is plug-and-play tubes. Used as a direct replacement for a fluorescent tube in a fixture, plug-and-play LED tube lights are installed without any rewiring to the fixture, keeping the fluorescent ballast.
Are T8 bulbs being discontinued?
US Department of Energy (DOE) regulations began phasing out various sizes of commercial fluorescent light bulbs in 2012. About all you can get today is the fluorescent workhorse of commercial lighting—the T81 bulb. By January 26, 2018 even T8s will be banned to align with new DOE energy efficiency standards.
Is G13 the same as T8?
A T8 tube is also called a TL-D tube from Philips and a Lumilux tube from Osram. You can recognize a T8 tube from it’s 28mm diameter. The socket is called G13 this because the 2 pins are 13mm apart from each other. . A T8 tube can work on an electronical ballast using a fixture without a starter.
Are T8 good for growing?
Four T8 fluorescent light bulbs will work well for growing vegetables indoors as long as you leave them on long enough to give the plants enough light.
Can you put a T8 LED bulb in a T12 fixture?
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 happens if you put a T8 bulb in a T12 fixture?
you have to remove the ballast- as most t8 tubes have an electronic one inside. If you put them in t12- you will burn the bulb up and they will work sporadically before they die. Also the fixture gets blackend.
How do you bypass the ballast for LED lights?
How to Bypass a Ballast

- Locate your ballast. …
- Cut the hot and neutral wires. …
- Cut the socket lead wires. …
- Remove the ballast. …
- Connect the input wires to the output wires.
