What sizes do tube lights come in?
While there are multiple types of LED and fluorescent tube lights, the three most common are T12, T8 and T5. The terminology comes from “T” for “tubular” and the diameter of the bulb in eighths of an inch, so “T8” represents a tube of 8/8ths of an inch, or 1 inch.
What is the standard size fluorescent tube?
T8s are 1-inch diameter fluorescent tubes, and they are the most prevalent of all fluorescent tubes. Four-foot T8s, in particular, are used everywhere – in hospitals, commercial office spaces, schools, retail spaces, warehouses… everywhere.
Which is better Tubelight or LED?
The efficiency of LED lights is very high. In comparison to ordinary incandescent bulbs, tube lighting has high efficiency. However, compared to LED bulbs, it is less efficient and makes it clear that LED bulbs are more efficient than tube light, and you can get yourself some of the best-LED bulbs from Jaquar.
How long is a T8 tube?

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.
Is LED better than fluorescent?
Better Energy Efficiency While fluorescent tubes are definitely more energy efficient than incandescent light bulbs and halogen lamps (which are just newer, brighter versions of incandescent bulbs) LEDs are even more energy efficient than fluorescents.
Which tube light is good for eyes?
Compact Fluorescent Lights (CFLs): CFL bulbs produce fewer UV rays and are more energy efficient than bright white incandescent and fluorescent tube bulbs.
How many watts is a normal Tubelight?
1. Energy Consumption
Technology | Ballast Factor | Operational Wattage |
---|---|---|
34 Watt T12 Fluorescent Tubes | 0.88 | 43 Watts |
16 Watt T8 Equivalent LED Tube | 1 | 16 Watts |
What does T8 or T12 mean?
A T12 lamp (on the left in the figure below) is therefore twelve-eighths of an inch, or one-and-one-half inches (3.81 cm), in diameter. A T8 lamp (on the right in the figure below) is eight-eighths of an inch, or one inch (2.54 cm), in diameter.
Can you still buy fluorescent tubes?
While the discontinued products may no longer be manufactured, they can still be sold until existing supplies are gone. In the meantime, consumers are likely to pay a premium for the lamps themselves, but also more in utility costs because these technologies use more energy.
Do tube lights use a lot of electricity?
Fluorescent lamps, including compact fluorescent lights (CFLs), use about 75 percent less energy than incandescent bulbs and last six to 15 times as long, according to the U.S. Department of Energy (DOE). But it’s widely believed that these popular bulbs use a lot of energy to start up.
