Which T8 lamp you choose: LED or fluorescent + simple change to lamp
Title: Luminescent 
Quite often, they will cross the light lines, crawling out the line, or such, call lamp lamps. Osventov is not spawned in the office itself, workers and public premises, but also in the housing fence. For a long time, the T8 fluorescent lamp has been used as a light source in such a lamp, but soon the technical LED colleagues appeared. Which source is better for lighting and how, if necessary, and change the standard LDS with LED, without and change the lighting body itself? For now, let’s talk about this experience and dissuade me from asking questions.
containment: 1. Construction and plinth 2. Species and characteristics on the lamp 3. Which illuminator is better - fluorescent or LED 4. Change to T8 fluorescent lamp with LED lamp
Construction and plinth
The T8 blade is structurally directed under the format on a pipe with a diameter of 25.4 mm (0.8 inch), in the edges on a g13 pin and base with a distance between the pins of 13 mm. These shields are used for storage on the lighting body and at the same time with the fixation in the lighting body. For the sake of the si format, the sources for the light line will be called linear or trubni.

Somehow you can see in the picture, the length of the charge may be different and depend on the power of the device, and this is not the intended purpose:

Most popular ca T8 devices with lengths of 600mm and 900mm.Illuminate the body with two takivas, byakha montirani everywhere, both in public institutions and in bitov and premises. Use 1200 mm and 1500 mm in order to cross each other and use it mainly for lighting in the industry and the public halls.
Find devices that are used for local clarification or in the confusion of body lighting: both surface-mounted and vgraded. A classic example is a tavanna lamp with four Armstrong lamps:
Rasterized illuminating body with four semiconductors and illuminating body t8 10 W 600 mm
Species and characteristics on the lamp
Contrary to the similarities, the appearance is different, but the T8 can and work on completely different principles. Dnes need a source for light from the base g13 ca:
- Luminescent.
- LED.
Fluorescent lamp T8
Fluorescent tube T8 is a fluorescent lamp (LDS), which is known. Kolbat on such a device is e plna from the livelihood of the bet, which, once again, shines a discharge of premine desperation, the soil and the radiation of ultraviolet light. Tazi is an ultraviolet light oath of phosphorus, which is slightly curved on the krushkata. As a result, the soil phosphorus shines on it, and ultraviolet radiation is harmful to the eyes, it absorbs from glass to trabata and samium phosphorus. Behind the starter and work on the lampata, there are two electrodes - spirals, preemptively for some time applying pres conjector g13, positioned in the margins on the trbat. For this, everything is prevented from turning the luminous discharge into the crankshaft into an uncontrollable random discharge, only by limiting it from a specially designed device for electronic control on the ballast, which at the same time is starting up at the crankshaft. Electronic ballasts can be both electromagnetic (EMPRA) and electronic (electronic ballasts).
Electronic ballast, montiran directly into the lighting body, starter starter and work on two fluorescent lamps of 18 W each
T8 LED bulbs
In such a device, yama zhivak and phosphorus and shine thanksgiving on the LED, put it in the bowl. The lighting on the LED can be different and depends on the power of the product (light power) and the size. There are two types of T8 LED lamps: with protected protection (driver) and without.
Please don’t seek out any additional devices and you can connect directly to a 220 V lighting network. The driver’s own driver repeats the type, for some reason for your own work, those sophisticated purchases are purchased on a special protective unit. This device converts the intervoltage into voltage, it is necessary to store it on the LED.

Which illuminator is better - fluorescent or LED
For yes, let's analyze these problems, let's compare the main predominance and lack of these two types of claims.
Comparative characteristics of fluorescent and LED tubes t8 with base g13
Luminescent LEDThe term for exploitation is 5 - 10 khiladi hours (depending on the frequency of switching on and the quality of the voltage) The term for exploitation is up to 50 khiladi hours Efficiency 80-100 lm / W 0 Hz In case of high-quality devices, the flutter is completely false, Euthyno The spectrum is wrong, Unpleasant for clear, enhanced from phosphorus protection However, in the spectrum of the purpose of the life cycle, under the condition that the manufacturer used to respond to the LED Low factor on the power on the verigata for the protection of the throttle valve (the level from the use of the electronic ballast) power 360 degrees on the stop of the tripod from the reflector lamp on the light depending on the design Variety of colors and temperature and colors and nuances Variety of colors and temperature and colors and nuances
Somehow, from the table, the main predominance is on the T8 fluorescent lamp - efficiency and durability - with interest, it's better with LED. The main disadvantage of the semiconductor and light sources is high delivery cost, but for the time being, you still intend to produce products and financial opportunities. At some point, it’s not a breeze, but the starter is equipped with a fluorescent lamp, but the electronic ballasts are more powerful than 1 T8 LED lamp.Please advise if you want to replace the fluorescent light with LED just for the sake of this reason. Osventova with the development of technology on the technology of svrhyarki diodi barzo poevtinyavat and dory sensible temples go out of their way to make their belly and economics so exploratory.
So the conclusion is not clear: LED source is good in any situation. The exclusion is ruled by the theses of the situation, some of which are impossible or difficult to turn on to illuminate the body with LEDs for some reason, for example, some are blocked from entering the factory structure. Tova mozhe yes bde problems for the organization.
Let's just figure out how to exchange T8 fluorescence for LED with minimal effort and go.
Change to T8 fluorescent lamp with LED lamp
Somehow brighten, some fluorescent, and T8 LED needs to be sized and equipped with connectors. Tova was significantly simply crushed into a single type of lamp from a friend directly into the illuminator. That is, if you always have a lamp using LDS, you don’t need to buy new ones, but you can avoid fluorescent lamps and LED analosi.
But simply skipping one lamp from contact and putting it on another is not enough. More tryabva and let's exchange the schematic for a self-illuminating body. Contrary to the foreseeable difficulties, it is enough to send it for everyone, who, for the first time, base knowledge on electrical engineering.
First of all, let’s see how a single LED lamp can be and is more than just a mrezhat. Depending on the model, the T8 semiconductor tube has a following wiring diagram:
Typical switching circuit for LED tube t8
In this case, lampite, which means that the veriga pres is a single connector (figuratively left), ordinarily, the driver is not included.And the lamp, which turns on the prez two connectors (figures clearly), imat the driver and can and can connect directly to the 220 V network.
Important! Some manufacturers will produce lamps with any pre-powered circuit, regardless of whether there is a driver included. When buying, do not take it away and tell how it turns on the lamp and how it saves the voltage!
Now let's say you have 2 standard T8 mugs. Unity without a driver (fig. left), others with graden (fig. vdyasno). How can we replace LDS with LED in a conventional lighting body designed for use with fluorescent lamps? Nay-lesniyat start and send the product and mate the semiconductor source to the light with a graded driver. For yes, send the comrade, it is sufficient and pervert two simple operations:
- disconnect the starter, which you will remove from contact;
- koso connection on gasta.
Wiring diagram for T8 LED lamp with 220 V driver instead of fluorescent lamp in standard lighting body
Ty kato droselt e with koso connection, that is not participating in the process on the storage on the lampata and, if desired, can be dory and be dismantled.
Ako accidentally or unknowingly bought a T8 diode lamp without a driver grade, togawa, wow, I’ll buy it again. In this case, the schematic for finalizing on a standard fluorescent lamp is also as follows:
Modification to fluorescent lamp for tube type t8 for LED tube lamp without driver
Tazi scheme, parse it, it's a little more complicated. But just as they taught good at the school and remember the electrical engineering, togawa such a revision is yama yes, it is difficult to see.
Dependence on visual perception on lightness from lampite on color temperature
So cheer up the lamp t8.Now you don’t know how the fluorescent lamp is different from LED, but you can independently and replace one type of lighting rod with another without special purchases for new bodies.
