Raster fixtures using linear or so-called tubular lamps are quite widespread. Moreover, they are found not only in offices, workshops and public buildings, they can also be found in residential buildings. As a light source in such lamps for a long time a t8 fluorescent lamp was used, but recently their LED counterparts have appeared. Which of the light sources is better and how, if necessary, to replace the standard LDS with an LED one, without changing the lamp itself? Today we will try to answer these questions.

Construction and plinth

The T8 bulb is structurally made in the form of a tube with a diameter of 25.4 mm (0.8 inch), at the ends of which there are pin bases g13 with a distance between the pins of 13 mm. These pins serve to supply power to the device and at the same time fix it in the lamp. Due to their shape, such light sources are called linear or tubular.

T8 tubular (linear) lamps with g13 base

As you can see in the photo, the length of the tube can be different and depends on the power of the device and its purpose:

Standard sizes of tubular light sources and their approximate power

The most popular T8 devices are 600 mm and 900 mm long. Lamps with two such bulbs were installed everywhere both in public institutions and in domestic premises. Tubes of 1200 mm and 1500 mm were less common and were used mainly for lighting industrial facilities and large public halls.

The shortest devices are used for local lighting or in raster fixtures: both overhead and built-in. A classic example is the Armstrong raster four-lamp ceiling lamp:

Typical scheme for switching on the T8 LED tube

At the same time, lamps that have a switching circuit through one connector (figure on the left) usually do not have a built-in driver. And lamps that turn on through two connectors (picture on the right) have a driver, and they can be connected directly to a 220 V network.

Important! Some manufacturers produce lamps with any switching scheme, regardless of the presence of a built-in driver. When buying, be sure to specify how the lamp turns on and what voltage it has!

Now let's say you have 2 t8 lamps with standard switching. One without a driver (fig. on the left), the other with a built-in one (fig. on the right). How to replace LDS with LED in a conventional luminaire designed for the use of tubular fluorescent lamps? The easiest way to do this is to have a semiconductor light source with a built-in driver. To do this, it is enough to perform two simple operations:

• disable the starter by removing it from the socket;
• short the throttle.

Wiring diagram for a T8 LED lamp with a 220 V driver instead of a fluorescent lamp in a standard lamp

Since the choke is short-circuited, it does not participate in the process of supplying the lamp, and if desired, it can even be dismantled.

If you accidentally or unknowingly bought a T8 diode lamp without a built-in driver, then, alas, you will have to buy it. In this case, the scheme for finalizing a standard fluorescent lamp will look like this:

Linear daylight fluorescent lamps are more economical (about 5 times) and have a longer service life (5-10 times).

A bit of history Inventor fluorescent lamp(fluorescent lamps) is considered Edmund Germer. He and his team in 1926 received white-colored light from a gas discharge lamp, the bulb of which was coated with a fluorescent powder inside. The General Electric Corporation later bought the patent from Germer and brought fluorescent lamps to widespread commercial use in 1938. The light of the first lamps resembled natural street light on a cloudy day (approximately 6400K): it is believed that it was then that the name "fluorescent lamp" appeared. In the Soviet Union, mass production of fluorescent lamps began only in 1948, for which in 1951 the developers of the first Soviet fluorescent lamp became laureates of the Stalin Prize of the second degree. Soviet GOST 6825-64 defined only three sizes of linear fluorescent lamps with a power of 20, 40 and 80 watts (600, 1200 and 1500 mm long, respectively). The flask had a large diameter of 38 mm for easier ignition at low temperatures.

Fluorescent linear fluorescent lamps are produced in many types: different power, length, with different bulb diameters, different bases and different light depending on the purpose of the lamp. What's more, this range will be even larger if you consider that energy-saving lamps are also fluorescent lamps with built-in starters.

Today, the most common linear daylight tubes are T8 (Ø 26 mm), T5 (Ø 16 mm) and T4 (Ø 12.5 mm). Lamps with a T8 tube have a G13 base (13 mm between pins), while T4 and T5 have a G5 base (5 mm between pins). T8 fluorescent lamps are currently available from 10 to 70 watts, T5 lamps from 6 to 28 watts, and T4 lamps from 6 to 24 watts. Naturally, the power of the lamps directly affects the dimensions (length) of fluorescent lamps: the ratios of sizes and powers are standardized. That is, an 18 W lamp with a T8 tube and a G13 base from any manufacturer has a length of 590 mm.

Also fluorescent lamps according to the color rendering index (denoted by Ra or CRI - color rendering index), that is, the ability to accurately display colors compared to natural light. So lamps with 100% color rendering (Ra=1) display all colors in the same way as in daylight sunlight. But the most common (due to sufficiency and greater availability) are lamps with a color rendering index of 70 - 89%.

Below we provide a description and specifications the most commonly used lamps, both in the industrial and municipal (where they are most common) and residential sectors. The luminous flux and lifetime values ​​below are approximate and may vary depending on the manufacturer.

Standard linear fluorescent lamps with T8 tube and G13 base

The most common type of linear fluorescent lamps. It is these lamps with a power of 18 W ("short") or 36 W ("long") that are remembered first of all when they hear the phrase "fluorescent lamp". And although the range of such lamps consists of models with power from 10 to 70 W, it is lamps with a power of 18 and 36 W that are most often used, which are interchangeable with Soviet fluorescent lamps LB / LD-20 and LB / LD-40, respectively. Linear fluorescent lamps with T8 tube and G13 base are mainly used in industry (warehouses and production halls) as well as in offices and municipal public institutions (administrations, schools, kindergartens). The average running time is 10,000 hours. The diameter of the T8 tube is 26 mm. They work both with electromagnetic chokes (EMPRA) in conjunction with starters, and with electronic ballasts (EPRA).

Standard linear fluorescent lamps with T5 tube and G5 base

T5 fluorescent lamps (unlike T8) are most common in the residential sector. They are narrower, and therefore lamps with them are better suited for lighting niches or kitchen tables under cabinets. The range of linear fluorescent lamps with T5 tube consists of models from 6 to 28 W (replacing incandescent lamps from 30 to 140 W). The lamps are mainly produced in 4200K and 6400K colors. T5 lamps have a G5 base (5 mm between pins). Average run time is 6000 - 10000 hours (depending on manufacturer and model). The diameter of the T5 tube is 16 mm. Used with electronic ballasts (electronic ballasts).

Wiring diagram for T8 LED lamps

To change the fluorescent lamp in the fixture to LED T8, remove the starter (the throttle remains in the same place) and install a new lamp. At the same time, the sockets of the cartridge remain as they are, because they are suitable according to the standard for these lamps.

Important: before starting work, do not forget to turn off the mains voltage!

Wiring diagram for LED lamps in T8 housing

Wiring diagrams for LED lamps in T8 housing

When replacing fluorescent lamps with LED ones, it is necessary to remove the starters and either short out the transformers. or remove them completely. If electromagnetic ballasts (any modification) or high-frequency electromagnetic ballasts (any modification) were previously installed, they must be removed together with the starters.

The output contacts of the lamps, located on one side, are closed. Therefore, it does not matter which pin is energized.

Change fluorescent lamps to LED lamps T8 G13

Replacing T8 fluorescent lamps with T8 LED lamps (recently often heard "LED tubes") is quite simple.

Externally, connecting T8 fluorescent lamps, or as they are also called G13 T8, is no different from connecting T8 LED lamps, or rather, not even connecting, but the installation process itself. The fluorescent lamp was taken out, the LED lamp was inserted.

The peculiarity of the installation is that for operation, the T8 LED tube does not require a gear, or more simply, it must be directly connected to the 220V power supply like a regular light bulb, while the power supply of fluorescent lamps at the time of starting requires a starter and a choke.

Therefore, in the luminaire itself, in which T8 LED lamps will be installed, the fluorescent lamp switching circuit is subject to change, i.e., it is necessary to rewire the wires from the mains directly to the cartridges into which the G13 base is inserted, bypassing the ballast (starter and choke).

It is quite obvious that it is most convenient to perform these works with the lamp removed, on the mounting table. Before starting work where the T8 G13 lamp will be replaced To comply with safety regulations, turn off the power to the luminaire in which the fluorescent lamp will be replaced. To do this, simply turning off the switch is not enough, since it can be turned on by strangers quite by accident during the replacement work.

Replacing a T8 G13 Fluorescent Lamp

To install the T8 G13 LED tube in place of the T8 fluorescent lamp, you must perform the following work: disconnect the wires from the starter disconnect the wires from the throttle connect the wires from the mains to the G13 cartridge, i.e. apply 220V voltage to the lamp directly, as shown in the figure.

At the same time, it is not necessary to completely dismantle the starter and throttle - the lamps serve 50 thousand hours for 7-8 years, and in the event of a change of office or premises, the lamps can be restored to work with fluorescent lamps, and T8 LED tubes can be used in a new place.

LED lamp T8 G13. Wiring diagram

Additional Information

LED lamp T8 are used in all luminaires that use T8 G13 fluorescent lamps with a length of 600 mm, 1200 mm, 1500 mm and a power consumption of 18W, 36W, 58W.

A luminaire in which a T8 fluorescent lamp is installed consumes more, since there are losses in the ballast. If the luminaire uses an electromagnetic ballast, then the actual consumption of the luminaire is about 20% more than the indicated consumption on a fluorescent lamp, if the control gear is electronic, then the consumption of the luminaire is about 8% more than the indicated consumption on a fluorescent lamp. Advantages of T8 LED tubes no ballasts (starters, ballasts and other ballasts) are required) it does not contain mercury, therefore it does not require disposal (utilization of fluorescent lamps is a rather expensive procedure) the power consumption of an LED lamp is 2 times less than fluorescent lamps T8 LED lamps do not flicker and do not tire your eyesight a lamp with a T8 LED lamp does not buzz, the service life is about 50,000 hours (against 5-8 thousand hours for a fluorescent lamp).

T8 LED lamp

MAIN CHARACTERISTICS

are a complete replacement noah by luminous flux fluorescent lamps T8 in a raster with a lamp.

Energy savings up to 50% compared to fluorescent lamps.

SPECIAL TECHNICAL ADVANTAGES

The most important factor that ensures the longevity of the lamp is the quality of heat dissipation from the LED chips. In addition to the main radiator, the Maxus LED lamp has an additional fin for heat dissipation. Due to this, heat removal from the mounting plate is carried out through 3 points.

Installation of LED chips is made on a double-sided printed circuit board and when using a special material of increased density, which also contributes to high-quality heat dissipation.

Modular board system

Soldering is not used to connect the parts of the lamp circuit board. All parts are connected using special gold-plated contact connectors. This type connection ensures the reliability and durability of the lamp.

The driver uses modern microcircuits that allow minimizing the size and refusing to use a high-voltage electrolytic capacitor. As a result, a PF of 0.93 is achieved, there are no current surges when the lighting is turned on. The high-performance DNC filter completely eliminates mains interference.

The driver is built according to the scheme of a galvanically isolated pulse-width modulator (PWM), a current stabilizer with feedback, which makes it possible to maintain a stable current on LED chips with high accuracy in a wide supply voltage range of 175-275 V.

PWM is designed for a maximum load of 35 W, which ensures optimal temperature conditions even when working under significant load.

LED tubes OgonOK T8-600

For effective replacement of obsolete lamps, an analogue of a fluorescent lamp of 18 W. These LED lamps have standard size and suitable for any lighting fixtures. In addition to low power consumption (6.5 W), the tubes are flicker-free, so they are safe for the eyes. The lamps are made of impact-resistant safe materials, they cannot be accidentally broken and injured by them.

When turned on, the temperature of the tubes is only a few degrees higher than the ambient temperature, so it is impossible to burn them. With a sudden voltage drop, the tubes will continue to work. All of these characteristics allow the use of these lamps in a variety of conditions, even close to extreme.

Advantages:

• energy savings compared to fluorescent lamps
• no ripples harmful to the eyes
• does not require special disposal
• does not beat
• Doesn't heat up, doesn't burn
• does not contain mercury and other harmful substances
• resistant to temperature and voltage fluctuations.

Specifications:

T8 LED tubes are becoming more affordable every year. In new construction, ready-made luminaires with T8 LED tubes can be used, and in reconstruction, it is possible to upgrade existing fluorescent ones.

In one of the last articles, I considered the economic effect of replacing fluorescent lamps with T8 LED tubes. Consider how LED tubes are connected.

To simplify the replacement of T8 fluorescent lamps with T8 LED tubes, manufacturers made the same base (G13) for LED tubes as for fluorescent ones, although only 2 contacts are required to turn on the LED tubes, not 4.

Seals, security holograms, documents, everything is in perfect condition. Additional equipment: timers for automatic control of meters, 63A circuit breakers in a 25A case, additional consoles.

The connection diagram for T8 LED tubes is very simple and is no different from the connection diagram for a conventional incandescent lamp.

Connection diagram for T8 LED tubes

To turn on the LED tube, it is enough to apply voltage to the lamp without using any additional devices. Unlike a fluorescent lamp, an LED lamp does not require a ballast.

If you have fluorescent lamps with T8 lamps, then after a slight upgrade, these lamps can be operated with LED tubes.

The connection diagram for T8 LED tubes instead of fluorescent lamps is shown below:

Wiring diagram for T8 LED tubes instead of fluorescent lamps

From an existing fluorescent lamp, it is necessary to remove the starter and short-circuit the throttle, i.e. it is required to supply voltage directly to the LED lamp.

At any time it is possible to retrofit back and use the same fluorescent lamps without incurring significant financial costs.

Cleaning mirrors: If the mirror is dull, it can be updated. In a glass of hot water, add 2 tablespoons of vinegar and 20-30 grams of chalk. Drain the well-mixed and settled liquid and wipe the mirror with it. After that, the mirror should be wiped with a dry soft cloth.

Remove water stains from furniture: Remove water stains from a polished surface by dusting it with flour and then rubbing it with machine oil.

Practical studies have revealed that when using raster lighting devices to create an LED lighting system, users do not need to purchase new lighting equipment.

The technical characteristics of the fixtures make it easy to install a diode light element in them. The most suitable way to perform this task is the built-in T8 LED lamp at 120 cm and 60 cm. The product is energy efficient, safe to use and guarantees a long service life.

Technical features of the T8 series lamp

These units are ideal for offices, industrial premises, commercial buildings, supermarkets and other types of shops. To date, lighting technology with built-in 4/18 W luminescent elements is no longer as popular as before. In their place came more advanced and small-sized T8 600 mm surface-mounted LED lamps.

If you already have 4x18 W fluorescent lighting devices, you can significantly reduce the cost of purchasing full-fledged LED lamps and upgrade the old ones for T8 tubular diodes with a g13 base. In the process of manufacturing the product, matte or transparent polycarbonate is used to create the case; a certain amount of LED elements.

T8 1200 mm LED lamps, the price of which has slight differences, are equipped with diodes in the same way. The devices have the required length, which is suitable for connection to a 2x36W fluorescent lamp.

To modernize lighting installations, it is not enough to supply a led t8 model of the appropriate length; it is also necessary to reconstruct the electrical wiring in the equipment itself. The LEDs have a direct connection system to a 220V electric current source.

Varieties of fluorescent lamps

To date domestic market offers a wide range of LED tube lamps, differing in the type of driver, power and dimensions.

According to the dimensions, the product is divided into three types according to the length:

• 600 mm;
• 900 mm;
• 1200 mm.

By design features, lighting has the following classifications:

• a device with an integrated driver inside a polycarbonate housing, below the diodes. The maximum voltage level is 220V.
• element with installed driver external type. The degree of voltage varies between 12-24V.

The body of the installation itself has a different coating, which provides a sharp or diffused glow:

• Frosted flask;
• translucent;
• Opaque glossy;
• Transparent.

Materials such as acrylic and polycarbonate can be used in the manufacturing process of the case. This raw material is characterized by high strength, reliability and long service life.

Dimensional parameters of lighting equipment

LED lamps, regardless of the type of bulb and internal components, have standardized dimensional parameters. In addition, the type of installation of the product is determined by the dimensions.

An analogue of a fluorescent lamp produces a powerful luminous flux and consumes electricity, depending on the dimensions of the lighting equipment. Each manufacturing company has individual standards that have significant differences.

Table with approximate parameters of the LED lamp.

600 mm	Т8 g13	880-1100 LM	10 W
900 mm	Т8 g13	1200-1300 LM	13 W
1200 mm	Т8 g13	1450-1900 LM	15-18 W
1500 mm	Т8 g13	2030-2365 LM	23-24 W

The value of color power can vary depending on the type of lighting equipment:

1. 2700-3500 K (Kelvin) - a product that produces white light with a warm tint;
2. 3500-4500K - white standard lighting;
3. Above 4500K - cold light with a light blue, slightly noticeable tint.

The most demanded modification is the device with standard white light. Its power rating is considered the best option, which does not have a strong effect on the eyes.

If you need to create a cozy and comfortable atmosphere in the room, you should give preference to the first option, which has a warm shade.

Connecting the T8 LED lamp

The scheme for connecting diode installations to fluorescent lamps is considered to be quite easy, not requiring certain experience and labor. However, you should first carefully study the step-by-step installation instructions, since there may be several installation options.

To simplify the reconstruction of luminescent elements for a T8 LED lamp, manufacturers equip the base of this element with the same dimensions - G13. The mounting system is fully consistent with the installation of conventional luminous parts.

To connect, you need to remove the starter from the luminescent device and reduce the inductor, thereby providing a direct voltage flow to the tubular diode.

Lamps of the T8 series have recently become in demand in the technical market. The reason for this is an economical solution to the problem of replacing a luminescent part with an LED. In this case, the base of the light source is not subject to modernization. LED lamp, according to the manufacturer, can last from 50,000 to 100,000 hours, which equals 20 years.

However, according to the statistics of domestic use of the device, the service life reaches given value in very rare cases. This is justified by the acquisition of low-quality LED parts. The limit of operation of such devices is 3-4 years of intensive use.
