T8 fluorescent tubes are wider in diameter, at 1 inch (2.5cm). The connector pins on each end of a T8 fluorescent tube are 13mm apart. It's called a G13 base, since the pins are 13mm apart. Note that older model T10 and T12 fluorescent tubes share the same G13 base as T8 tubes - so a T8 LED replacement tube light will work just fine in a T10 or T12 fixture.

Buyers of LED fluorescent replacement tube lights often ask if they can use a T8 sized LED tube in a T12 fixture. We cover most of the basics on but customers are often confused after purchasing when they receive an LED that is marked as T8.

T8 Lighting:What Is The Actual Lumen Output For T8 Fluorescent Bulbs?

T8 32-Watt Cool White (4100K) ALTO Linear Fluorescent Light Bulb (30-Pack) .. Here is a picture of just one T8 LED tube light, installed on the left, compared to two fluorescent tube lights, on the right. Even just one LED tube light is brighter than both the fluorescent tubes. The LED tube also seems brighter, and I don't notice any flickering. It takes about a second to warm up before it turns on, which doesn't bother me in the least.

Ballast Bypass type LED tube lights are extremely easy to install - just unscrew the fluorescent tube, and screw in the T5 or T8 led fluorescent tube replacement. They are true plug and play led tubes lights.

How well do T8 fluorescent lamps maintain light output

If you are looking for the best way to maximize your T8 fluorescent lighting, there are some general guidelines to keep in mind. Over the last 20 years, there have been many advancements in the quality of lighting for both industrial and residential use. Most of these advancements have come in better efficiency and light output with concerns to fluorescent lighting. These technological breakthroughs have increased the range of the spectrum cast by the lighting as well as enabled the ballasts to be more efficient in many different conditions. With these points in mind, there are a few more adjustments you may perform to increase your T8 fluorescent lights within your home or place of business.Now consider the arguments for replacing T8 fluorescent.
1. While it is true that the T8 fluorescent lamps put out more lumens per watt than current LED lamps, not all the light they generate is useful. What is useful is light radiated where we want it. Light that is radiated 360 degrees around a tube is that useful unless it is reflected (with losses) to where we want it. Thus, the rating of lumens generated is kinda a misleading efficiency indicator.
2. An LED light has a better ability to point light where needed and not “waste” light where not needed.
3. Current costs of T8 ballast by-pass LED light tubes are about $9 each and are still falling.
4. True most LED bulbs have a 50,000 hour rating life and slowly get dimmer after that. But, with LEDs there are less components in the fixture to fail. A standard fluorescent has the bulbs and ballast, while the LED has only the bulbs. Ballasts also have a failure rating about the same as the fluorescent bulbs making the effective failure of the light less than 25,000 hours depending on how many bulbs are in the fixture.
5. When a light fails, which way do you want it to fail: A. completely dark or B. dim? I would rather change a dim light knowing a bulb will fix it rather than a dark bulb to find out it is a bad ballast, or power problem.
