T8 tube. A very ordinary kind of lamp. Are energy saving lamps counted?

It's not an energy-saving lamp, just an ordinary incandescent tube, you can directly replace the incandescent tube with an LED tube, the LED tube is a little more expensive, but the light efficiency is high, 8W is as bright as the 30W of an ordinary tube. Or as the following friend said, replace the lampholder with energy-saving lamps, it is best to replace it with e27, home, more ordinary, easy to buy. It's beautiful and bright, and it's super power-saving, and my living room is very bright with a 15W 6400K.

The bedroom generally uses a warm energy-saving lamp of about 3000k, which is not dazzling, very soft and comfortable. Hope mine satisfies you.

Of course, forget it, but it is better to divide the electronic ones into the inductive ones. His disadvantage is that there are many components, troublesome maintenance, and large volume, but it is also its advantage that it is evenly distributed than energy-saving lights, which can be replaced by T5 (higher light efficiency), and can also be replaced by integrated compact fluorescent lamps (commonly called energy-saving lamps), which is easy to maintain.

In the past, the ordinary T8 bracket was full of inductive ballasts, which started slowly and flickered, because they used halogen powder tubes, which had large light decay and were not energy-saving.

The current T8 magnetic conductor, that is, the electronic ballast, will be a little better than the previous inductive T8.

But if you have installed T8, there is no need to remove the lampholder, just replace the original T8 lamp tube with the bracket of T8 to T5, remember to take off the starter!

Using T8 to T5-28W is brighter than the original T8-40W, and the better lighting effect 28W is definitely more power-saving than the previous 40W.

T8 to T5, T5 bracket lamp, is the trend of development, many cities have been used for a long time.

Interested can contact further ** this issue.

Whether it is an energy-saving lamp.

First of all, see whether the lamp is coated with "rare earth trichromatic phosphor", and the ordinary fluorescent lamp is coated with "halogen powder".

Let's see if it is an "electronic ballast".

Usually, energy-saving lamps are T5 or below.

What you said should not be an energy-saving lamp, but an ordinary fluorescent lamp, which is more energy-efficient than incandescent lamps and worse than real energy-saving lamps.

If you want to use real energy-saving lamps, you have to get rid of those things and buy them. Install a lampholder like an incandescent lamp and press the energy-saving lamp.

Difference in size: T8 tube size is 26mm, T5 tube size is 16mm, T5 tube diameter is smaller. Calculation:

T8 Diameter T*8 1 inch 26mm T5 Diameter T*5 5 8 inch 16mm where T is the diameter **, T 1 8 inches. The difference in brightness and energy saving: Because the diameter of T5 tube is much smaller than that of T8 and T12 lamps, the elastic collision probability between the noble gas atoms and electrons filled by the lamp is higher, and the energy loss is smaller, which is also very beneficial to the improvement of light efficiency.

Because the inert gas filled with is a unique inert mixture, it can not only better protect the cathode of the lamp and help the lamp to jump, but also can appropriately reduce the lamp inflation pressure. Further increase the luminous flux output of the lamp. As a result, although the power of the lamp is lower, the total luminous flux is not reduced, so that the light efficiency of the lamp is improved, which means that T5 is brighter and more energy-efficient than T8.

The difference in length: The average T5 lamp is 5cm shorter than the T8 lamp (the length is different, the interface is not the same), so we should fully consider the size of the lamp when we carry out the project transformation, if the previous lamp plate is used T8 lamp plate for energy-saving transformation and use LED, you can directly replace it with the LED T8 lamp, if you want to change the T5 lamp to be more energy-saving, you need to add a conversion bracket to install it. However, please note that if you use the T5 lamp panel for energy-saving transformation, you can not replace the LEDt8 lamp, because this cannot be installed, unless the lamp plate is replaced, but the cost is too great, so you can only use the LEDt5 lamp to replace. 5

T5 and T8 lamps belong to fluorescent tubes, and compared with LEDs, the luminous efficiency of LEDs is nearly twice as high as that of fluorescent tubes at the same power.

If you use fluorescent tube 40W, now use LED lights, choose 20-30W is enough. In contrast, LED lights are more energy efficient.

Let's answer this question simply and clearly. The biggest and main difference between T5 and T8 lamps is the difference between the circuit board and the driver. Because the volume determines the size of the circuit board, the size of the circuit board determines the size of the current voltage, and the size of the current voltage determines the size of the lighting power.

As for energy saving, the same product has the same degree of energy saving, because LED itself has the function of energy saving. Personally, I think the T8 is more energy-efficient than the T5 because the T8 has better heat dissipation than the T5.

1: Energy saving does not look at the lamps How to distinguish whether the lamps are energy-saving.

As you said T5 and T8, how to distinguish which one is more energy-efficient, you should use 2 points to compare: A: their power B: their luminous flux.

For example, the power of T8 is 18W, the luminous flux is 2800LM (lumens), and the power of T5 is 12W, and the luminous flux is 2200LM.

t8:2800/18=155lm/w t5:2200/15=146lm/w

The T8 is more energy efficient.

The biggest difference between T5 and T8 for lighting in the factory workshop is that the pipe diameter is different, and the pipe diameter of T5 is relatively thinner. The common specifications and sizes of T5 lamps are Hehe, which are mainly used in factory workshop lighting and office spaces, supermarkets and shopping malls, and can be used to replace T8 and T5 traditional fluorescent tubes. Let's find out with 100% lighting now!

1. The T5 lamp adopts a high transmittance PC lampshade, and the built-in plate is an aluminum alloy circuit board, which has good thermal conductivity and heat dissipation, which greatly guarantees the life of the lamp.

2. The lamp bead model is 2835, with high brightness and more stable light efficiency.

3. The constant current IC drive fully guarantees the stability of the current.

LED energy-saving popularization of integrated lamps began to be widely used in factory workshop lighting, ballasts were replaced by built-in constant current drives, and the integration directly replaced the bracket and fluorescent tubes, which were more secure in use and later use.

The traditional lamps used in the lighting of the factory workshop are different from the LED tubes, which are lighting fixtures that do not require starters and ballasts. The chip is used as the light source, and the single-tube wiring shell is mostly made of PC material. The summary of everyone's questions about LED lights is answered here one by one:

1. On the issue of quality assurance.

Regarding the warranty of LED tubes for lighting in the workshop, the warranty of LED products on sale is 3 years, and it is promised that if there is a quality problem in the middle, contact customer service to give replacement treatment.

2. On the issue of light decay.

The light decay within the normal range is normal, and if you want to have a long life of the lamp, you also need to understand the heat dissipation and other related aspects.

3. Misunderstandings.

The difference with the traditional light source is mainly in use, because the lamp itself has its own driver and light source, and the ballast and starter on the bracket need to be removed when in use, which is a major aspect of the customer's reflection problem, which is not a quality problem and a problem of use and operation.

T5 and T8 are only different in outer diameter, which has little impact on the energy loss of LED lamp beads, and it is impossible to compare which one is more energy-saving.

t", to put it bluntly, actually represents the diameter of the lamp. Each "t" is 1 8 inches. Everyone knows that an inch is equal to a millimeter. Then the diameter of the T8 lamp is: The remaining figures correspond as follows:

T12 diameter mm

t10 diameter mm

T8 diameter mm

T5 diameter 16 mm

t4 diameter mm

Diameter mmt2 Diameter mm

Theoretically, the thinner the lamp, the more efficient it is, which means that the same wattage emits more light.

T8 is much thicker than T5.

The diameter of T8 is about 3 cm, and the diameter of T5 is about cm.

T8 power: 36W (about 120 cm) 30W (about 100 cm) 18W (about 60 cm).

The power of T5: 28W (about 110 cm) 21W (about 88 cm) 14W (about 55 cm) 8W (about 30 cm).

T5 is a new type of lamp and T8 is an old type.

The main difference is that in appearance the T5 is smaller and thinner, and the T8 is thick and long.

Intrinsically, T5 is between 50 and 40 percent more energy efficient than T8.

And the life span is nearly 1 times longer than that of T8.

T5 fluorescent lamp has good color rendering performance, because it uses rare earth trichromatic phosphor configured by red, green and blue three primary colors, so the color rendering index Ra can reach more than 80.

Moreover, T5 fluorescent light has high efficiency. The luminous efficiency of a T5 fluorescent lamp with a correlated color temperature of 2700K is about 100lm W, while the luminous efficiency of an ordinary T8 fluorescent lamp is about 70lm W, and the luminous efficiency of an ordinary T12 fluorescent lamp is about 60lm W.

T8 is the kind of 40W lamp at home, there are 40W (36W W, 20W, (18W) and so on, the length of these wattage lamps is different, but the thickness is the same; T5 is a much thinner tube than it, there are 28W, 21W, 14W, etc., T4 is a thinner tube than T5, you will know it when you go to the lamps and lanterns that are sold.

T8 has high power but high brightness, T5 has little power and small brightness, and other specifications are the same.

First, most of the energy-saving lamp phosphor is mixed powder, that is, the three primary color powder and halogen powder are mixed in a certain proportion, and some unscrupulous manufacturers use pure halogen powder, the light efficiency of pure halogen powder is about 48lm w, and the fluorescent light effect of T5 straight tube has reached more than 85lm w, and some manufacturers can even reach 90-92lm w

2. Because of the spiral or multi-U-shaped structure of energy-saving lamps, the lamps are blocked from each other, and a large part of the light cannot be directly illuminated, resulting in a decrease in the utilization rate of light efficiency.

Hello dear, the differences between T8 ordinary lamps and T8LED tubes are as follows: 1. Different sizes: the word Xiang La's mother T is equivalent to 1 8 inches of Zen, so the diameter of T8 is 26 mm, and the LED is 16 mm.

2. Different lengths: LED tubes will be 5 cm shorter than T8, which also causes the two interfaces to be different. 3. The brightness is different

The LED tube diameter is small, but its brightness is stronger than that of T8, and it is more energy-efficient. 4. Different applications: T8 is mainly used in public areas, such as square signs, factories and hospitals, platform advertising, etc., and can also be made into a built-in power supply, while LED is limited by its own pipe diameter, which is difficult to do.

This question can be directly read to the encyclopedia.

T8 lamp is a kind of fluorescent lamp (or fluorescent lamp, fluorescent tube, fluorescent tube), with a diameter of 1 inch and about 25 mm, which belongs to a type of gas discharge lamp. It uses electricity to activate mercury vapor in argon or neon to form plasma and emit short-wave ultraviolet light, which causes phosphorus to fluoresce visibly for illumination. Typical fluorescent tubes are made of glass and have sockets at both ends to connect to the power supply and secure the position of the fluorescent tubes.

T refers to the English word tube, 8 refers to the diameter of the lamp, T8 is the diameter of eight eighths of an inch of the tube, that is, one inch diameter of the tube, one inch is, so the diameter of T8 is 26mm

T5 and T8 are CFLs

LED lamps are a type of semiconductor that converts electrical energy into visible light.

Comparison of LED light brightness and ordinary light brightness.

About brightness and energy saving comparison: 1W LED = 3W CFL (Energy Saving Lamp) = 15W Incandescent 3W LED = 8W CFL (Energy Saving Lamp) = 25W Incandescent Lamp 4W LED = 11W CFL (Energy Saving Lamp) = 40W Incandescent Lamp 8W LED = 15W CFL (Energy Saving Lamp) = 75W Incandescent Lamp.

You're t8 on the picture.

1. The difference between the size of LED tube T5 and T8 T stands for "tube", which means tubular, and the number behind T indicates the diameter of the tube, T8 is that there are 8 "T", and a "T" is 1 8 inches, and one inch is equal to millimeters, so each "T" is. The diameter of the T8 lamp is 26mm, and the diameter of the T5 lamp is 16mm. 2. The difference between the length of LED tube T5 and T8 is that the average T5 tube is 5cm shorter than the T8 tube (the length is not the same, and the interface is not the same).

3. The difference between the brightness of LED tube T5 and T8 is that the diameter of LED lamp T5 is much thinner than that of T8 and T12 tubes, and T5 is brighter and more energy-saving than T8. 4. The difference between the application of LED lamp T5 and T8 T5 and T8 two kinds of lamps have their own uses, T8 lamps are widely used in public areas, factories, hospitals, government agencies, bus advertising, stations, etc., T8 is everywhere, and T8 tube is easy to integrate built-in power supply, T5 due to the diameter is too small, it is difficult to drive the power supply directly inside the traditional lamp, and only through integration can the power supply be built-in or directly adopt the external power supply method.
