A fluorescent lamp, or fluorescent tube, is a low-pressure
Mercury-vapor lamp – Wikipedia
gas-discharge lamp that uses fluorescence to produce visible light.
What are the long light bulbs called?
Tube lights, also known as linear light bulbs, are frequently used in office buildings, kitchens, work spaces and commercial installations as well as homes, with varying sizes and brightness levels.
What type of fluorescent tube do I have?
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. Fluorescent tubes are measured in eighths of an inch.
What are tubular lights called?
The fluorescent tube, also referred to as the fluorescent strip or tube light, is a low-pressure mercury vapour gas-discharge tube that converts fluorescence into visible light. Fluorescent tubes have the advantage of benefitting from much greater energy efficiency than incandescent lamps.
What kind of lights are the long tubes?
Linear fluorescent tubes are the most common type of fluorescent lamps.
Are T8 and T12 interchangeable?
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 is the length of fluorescent tube?
Common tube ratings Tube diameter in 1⁄8 in (3.175 mm) Nominal length Nominal power (W) T8 4 ft (1,219 mm) 36 T8 5 ft (1,524 mm) 58 T8 6 ft (1,829 mm) 70 T12 14–14.5 in (356–368 mm) 14,15.
How do I know which tube light to buy?
First, you will need the diameter or how wide it is around. This is expressed as a number such as T8 or T12. The “T” stands for tubular, and the number is a measurement of the diameter in 1/8″ increments. So a bulb with a 1″ diameter would be a T8—eight 1/8″ increments.
What is the difference between T8 and T12 light bulbs?
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 I replace fluorescent tubes with LED?
Yes, you can replace fluorescent tubes with LED tubes or LED-integrated fixtures. If you just want to replace the bulbs, you can use plug-and-play, direct-wire, or hybrid LED tubes. Plug-and-play tubes are the easiest to install as they do not require any rewiring to the fixture.
What is T5 tube light?
T5 lamps are fluorescent lamps that are 5/8″ of an inch in diameter. Differences in length and socket pin design versus conventional fluorescent lamps prevent any problems with electric circuits or human factors.
How many types of tube lights are there?
Yes, there are three different types of tube lights and they are T12, T8 and T5 tube lights.Different Types of Tube Lights – T12, T8 and T5. Tubelight (type) Diameter (inches) Length (inches) T12 (regular) 1.5 48 inches T8 (thin) 1 48 inches T5 (Ultra thin) 0.62 45.2.
How does a fluro light work?
A fluorescent lamp generates light from collisions in a hot gas (‘plasma’) of free accelerated electrons with atoms– typically mercury – in which electrons are bumped up to higher energy levels and then fall back while emitting at two UV emission lines (254 nm and 185 nm).
What is a Balaster?
ballast – A device required by electric-discharge light sources such as fluorescent or HID lamps to regulate voltage and current supplied to the lamp during start and throughout operation.
Can I 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.
What size is a T5 tube?
T5 Fluorescent Tubes (15mm Diameter).
Can I use T5 bulbs in a T12 fixture?
T5 lamps cannot replace T12 or T8 lamps because of differences in physical and electrical characteristics. T5 lamps come in different lengths than T8 and T12 lamps. A nominal 4-foot T5 lamp is actually shorter than an equivalent T8 lamp [1149 millimeters (45.23 inches) in total].
What is better T12 or T8?
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. For some applications, one T5 bulb can replace two T12 bulbs, providing even greater energy savings (a process called “de-lamping.”)Oct 9, 2015.
Which is better T8 or T5?
If you do not need as many lumens, the lesser wattage T8 would be the better choice since it offers lower lumen and watt consumption. If you need higher levels of lighting, the T5 might be ideal for your situation.
What is a T8?
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.
