As my practice shows, many people do not know that when using raster lamps there is no need to buy new ones in order to install LED lighting. The simplest and effective method, this is an upgrade with T8 LED lamps for 600 mm and 1200 mm.
Such ceiling lights are common in offices, shops, and office spaces. As a rule, they are mounted in Armstrong suspended ceilings. But in addition to built-in ones, there are also overhead models. They are now outdated and too thick. They were replaced by new diode ones with a thickness of only 1 cm, convenient to install using an overhead type of installation.

Types of T8 lamps
T8 lamps, also marked G13, are also called T8 LED tubes. Externally, this is also a tube made of matte or transparent polycarbonate, but the filling consists of LEDs. The dimensions fully correspond to luminescent ones, standard sizes are 600 mm, 900 mm, 1200 mm.
Structurally, they are of two types:
- the driver is installed inside the tube under the LED diodes, accordingly, it is powered by a voltage of 220V;
- An external driver is used, like from an LED strip, powered by a voltage of 12V.
Built-in drivers for 220 volt models
According to their design, flasks are divided into 3 types:
- transparent, 0% loss;
- translucent, satin, loss 10%;
- matte, not transparent, light loss on average 20%.
The flask is made of acrylic plastic or polycarbonate, which gives good mechanical strength.
Standard sizes:
- 300mm. for desktop;
- 600mm. for Armstrong ceiling lamps;
- 900mm;
- 1200mm.
The luminous flux increases in proportion to the length, the length has increased 2 times, it shines 2 times brighter.
The color temperature has the same characteristics as LED lamps:
- warm white light;
- neutral white, daytime;
- cold, bluish compared to warm.
Of these options, the best one is neutral daylight, the eyes perceive it best, a white sheet of paper will be really white and will not turn yellow as if it were warm.
Benefits of replacing with LED
Let's calculate how profitable it is to install new diodes instead of fluorescent ones. We take into account that they are placed on an Armstrong suspended ceiling and shine in all directions. Due to the limited dimensions of the body itself, the body of the tube obscures its reflected light. The calculation was made by an electrician, he has more extensive experience in this.
Let's carry out a simple calculation for gas-discharge systems, which will involve:
- Efficiency of all luminescent from 70%
- shading coefficient of light flux when reflected from a mirror reflector, 0.6-0.7;
- light source efficiency 50-60 Lm/W;
- service life no more than 18,000 hours.
For diodes, these values will be respectively:
- 90% efficiency depends on the power supply;
- 0.9 because it only shines down;
- 100-120 Lm/W for medium price category;
- up to 50,000 hours, after this period the brightness will decrease to 70% of the original.
Using the above coefficients, you can make your own calculations. A diode light source is 2 times more efficient and economical only in terms of electrical parameters. If we take into account the service life, then in the end the superiority of new technologies will be 4 times.
At low temperatures, the efficiency of gas-discharge sources decreases, while that of diode sources increases. This factor should be taken into account when making calculations.
Which T8 lamps to choose?
A large number of readers ask which lamps to choose and where is the best place to buy. If you are interested in high-quality and proven T8 LED lamps, I recommend buying Philips. They provide European quality; the requirements for lamps in Europe are much stricter. Philips does not inflate the specifications, as domestic brands do.
I checked many stores looking for the best value for money. The best was the discount store Sibertek.ru Online store of chandeliers and lighting fixtures The first discounter in Russia, Wholesale prices retail.
Types according to connection diagram
Installation and connections of T8 LED tubes
Let’s determine in advance that the ballast is a ballast, the same as the ignition unit for xenon. Electronic ballasts are an electronic version that performs the starting function.
According to the connection diagram, they are divided into 3 types:
- regular connection instead of standard luminescent ones, as a rule they are only compatible with old electromagnetic ballast and cannot be installed with electronic ones;
- The ballast is removed and the tube is connected directly to 220V;
- The ballast is dismantled, the new ice bulbs are powered by an additional 12V power supply.
In fact, the model with a built-in driver is a full-fledged lighting device that only requires a 220V socket and a wire. Therefore they can be completed electrical wires with special plug and switch.
All connection options with built-in driver
Wiring connections depend on the model, please check before purchasing:
- connection on the left side;
- from the right;
- at both sides.
T5 lamps
Difference between T5 (above) and T8. Set of wires for separate connection
T5 lamps are a variation of T8. They are widely used in retail counters, especially with refrigerators. A long light source is suitable for the aquarium; sometimes LED strips or rulers are installed, but they are not splash-proof. In addition, the fish may try to tear off the LED, mistaking it for food.
Simple modernization of the lamp
In addition to the standard types of installation of G13 T8 diode lamps, I also have my own designs that you can repeat with your own hands. My method is 2-3 times cheaper, but a little more complicated. Based on the use of LED strips and 12V power supplies. Appearance It will turn out different, but no worse. Do you often look at the ceiling indoors? In addition, they are covered with bars to prevent blinding.
The body of the raster lamp has a reflector installed on the base, which we use.
- remove fluorescent tubes;
- remove the ballast filling;
- glue it onto the reflector LED strip SMD 5050 density 60 LEDs per meter;
- glue 8 pieces of 50 cm each;
- we combine food;
- install and connect the power supply.
The rated brightness of the standard is 3600 Lumens, taking into account losses the result is about 650 Lumens from one tube. 1 meter on SMD 5050 LED diodes gives about 700 Lumens. In order not to glue 8 pieces of 50 cm each, you can use double-width tape, you will get 4 pieces.
Such modernization increases maintainability and significantly reduces its cost. Even if the LED diode fails, only a segment of 3 LEDs will go out.
For one rework, one will need 4 meters, 700 Lumens per 1m. it will be 2800 lm, a little less, but not significantly. You can also use a more powerful option, for example ice rulers on SMD 5630 and 5730. You will only need 150cm of them, 3 pcs. 50cm each.
Upgrade cost
Let's calculate what benefits we will get from independent modernization.
Let's calculate the rework.
- tape price 135 rub./m.;
- 4m. cost 540 rubles. This is enough to replace 4 tubes;
- at the usual way it will cost from 1200 rubles, with a minimum price of one 300 rubles.
In order not to install 1 unit for each, we will install 1 power supply for 4-6 lamps.
Let's calculate for an office 6 fluorescent pieces.
- my method: 540 * 6 = 3240 rub., plus 1000 rub. to the power supply;
- regular: 8400 rub.;
- total: mine from 4240 rubles, regular from 8400 rubles.
The gluing procedure is very simple:
- wipe the installation site;
- carefully glue;
- put connectors on the ends or solder wires;
- put all the pros and cons together.
Anyone who has ever held a soldering iron or changed a T8 G13 lamp can handle this. And for those who are really bad with this, amateur radio stores sell ready-made kits with ready-made step by step instructions for replacement with diode strips.
Replacement video
A foreign colleague will tell you and show you how to properly replace them with diode ones. Everything is shown in great detail and will be clear without words or translation.
Price example
Beware of Chinese products without a listed manufacturer. The Chinese are lying when it comes to LEDs. They use their favorite method: they install a weak crystal in a standard LED diode housing, the power of which is 3-5 times less than the branded one. And the characteristics are written on the product, as if branded LEDs were installed.
But on the domestic market there are inexpensive and good models With affordable price from 290 rub. for 1 piece
But the best way is to sell the installed old raster ceiling lights and replace them with modern LED panels. Their thickness is 1-3cm. and the cost for small wholesale purchases is from 1000 rubles. for the 3600 lm model. with Japanese quality diodes.
Linear fluorescent fluorescent lamps are more economical (about 5 times) and have a longer service life (5-10 times).
A little history Edmund Germer is considered the inventor of the fluorescent lamp (fluorescent lamp). He and his team in 1926 obtained white-colored light from a gas-discharge lamp, the bulb of which was coated inside with fluorescent powder. 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 this is when 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 standard sizes of linear fluorescent lamps with a power of 20, 40 and 80 watts (length 600, 1200 and 1500 mm, respectively). The flask had a large diameter of 38 mm for easier ignition at low temperatures. |
Fluorescent linear fluorescent lamps are available in many types: different power, length, with different bulb diameters, different bases and different light levels depending on the purpose of the lamp. Moreover, 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 fluorescent lamp tubes are T8 (Ø 26 mm), T5 (Ø 16 mm) and T4 (Ø 12.5 mm). T8 tube lamps have a G13 base (13mm between pins), while T4 and T5 have a G5 base (5mm between pins). T8 fluorescent lamps are currently available in wattages from 10 to 70 W, T5 lamps from 6 to 28 W, and T4 lamps from 6 to 24 W. Naturally, the power of the lamps directly affects the size (length) of fluorescent lamps: the ratio of sizes and powers is 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 have a color rendering index (indicated 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 the same as in 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 lumen output and lifespan 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 precisely these lamps with a power of 18 W ("short") or 36 W ("long") that are first remembered when they hear the phrase "fluorescent lamp." And although the range of such lamps consists of models with a power of 10 to 70 W, the lamps with a power of 18 and 36 W are most often used, which are interchangeable with Soviet fluorescent lamps LB/LD-20 and LB/LD-40, respectively. Linear fluorescent lamps with a T8 tube and a G13 base are used mainly in industry (warehouses and production workshops), as well as in offices and municipal government institutions (administrations, schools, kindergartens). The average operating time is 10,000 hours. The diameter of the T8 tube is 26 mm. They work both with electromagnetic chokes (EMG) in conjunction with starters, and with electronic ballasts (EPG). |

Standard linear fluorescent lamps with T5 tube and G5 base |
|
|
|
T5 fluorescent lamps (as opposed to T8) are most common in the residential sector. They are narrower, and therefore lamps with them are better suited for illuminating niches or kitchen tables under cabinets. The range of fluorescent linear lamps with T5 tube consists of models with power from 6 to 28 W (replacement of incandescent lamps from 30 to 140 W). Lamps with colors of 4200K and 6400K are mainly produced. T5 lamps have a G5 base (5 mm between pins). The average operating time is 6,000 - 10,000 hours (depending on the manufacturer and model). The diameter of the T5 tube is 16 mm. Used with electronic ballasts (EPG). |

Linear LED lamps replaced the old T8 tubes. Great energy savings are achieved by using LED elements.
Fluorescent lamps are produced in lengths of 600 mm and 1200 and 1500 mm (sizes 600/1200/1500). They can easily replace traditional T8 (G13) tube fluorescent lamps, as they can be used on 110-240 VAC, and also have an increased service life, bright light and do not pollute the environment. These led lamps are used for lighting, in most cases, public places, such as: offices, warehouses and production facilities of factories/factories, supermarkets, schools, parking lots, airports and much more.
Why is it worth buying T8 LED lamps:
- Energy savings up to 60%. High efficiency;
- Service life 5 years;
- Instant on, no flickering or changing lighting;
- The power source is a highly efficient DC power supply (95%), as well as a special thermal insulation protection system. The DC control device may operate under unstable electrical voltage;
- Lack of electromagnetic and radiation waves;
- Environmental Safety. Does not contain mercury, heavy metal fumes and is not harmful to the environment.

Introducing LED linear lamps T8, produced by the company – our long-time partner in LED lighting products. These types of LED lamps are similar in shape to conventional tubular fluorescent lamps. They got the name linear because they provide a line of continuous light.
Such lamps look very organic in corridors or elongated rooms. They are usually placed parallel to the long axis of the room.
Abbreviations and numbers in the marking of a T8 lamp with a G13 socket
According to the designation system used in the USA, linear or tubular lamps are marked with a capital letter “T” and a one- or two-digit number. The letter T is an abbreviation of the English word “tubes” or “tubes”. The number indicates the diameter of the glass tube of the lamp.
IN American system designations of linear fluorescent lamps (in the USA they are called fluorescent), the digital part corresponds to an integer multiplied by 1/8 inch. For example:
- T2 is 2/8 inch or 0.25 inch (“finger”) or in and equals 1/4 x 25.4 mm = 6.35 mm;
- T5 – 5/8 in or 15.875 mm;
- T8 – 8/8 in – 25.4 mm;
- T12 – 12/8 in or 38.1 mm.
To simplify, the diameter is rounded to convenient values - 6, 16, 25, 38, etc. Therefore linear LED lamp Led T8 has a real diameter of 25.4 mm, conventionally rounded to 26 mm.
The length of a llama's bulb is usually proportional to its power. For T-type LED lamps with a two-pin G13 base, the website offers three lengths - 600, 900 and 1200 mm.
T8 tube lamps with LEDs
LED linear lamps with G13 socket are intended to replace fluorescent lamps in previously manufactured luminaires. They have appropriate installation dimensions and lighting characteristics. Lamps T8 220V They operate directly from AC power, so they do not require separate power supplies.
An example of such lamps would be a lamp of the ECOTUBE category model.
A special feature of the lamps presented on the site is a rotating base. A flat LED strip is installed in the lamp tube, giving light not in all directions, but only in one direction. After installing the lamp in the lamp, you can turn it and direct the flow of light in the required direction. This feature is reflected in the lamp marking with the letters DR (Dado Rotating - rotating base).
