It cannot be denied that LED tube manufacturers make great contribution to the world by inventing T8 LED tube light, which is energy efficient, durable, environmentally friendly and so on. But it is far away from being an ideal light. Therefore, it is not widely spread and there is still a long way to go to replace low efficient lightings like fluorescent light with T8 LED tube light.
 
Why it is imperfect is that it is of high price. Most of families cannot afford to use it as home lighting. In addition to high price, there are other problems which make it impossible to use T8 LEDs universally for the time being. Let me explain the problems in the application of T8 LED in detail.
 
First of all, now the color temperature of some LEDs are relatively high. Blue spectrum makes people feel uneasy, so these LEDs fail to create a comfortable environment. What's worse, the light of these LEDs are not soft enough to protect eyes.
 
Secondly, the driving circuit designed for LEDs needs to be improved and regularized. Designers must work on life span, power consumption, power factor and other aspects.
 
Thirdly, heat dissipation is another problem needed to be dealt with. This is vitally important because to some extent, it determines the life span of LEDs. At present, most of the LED tubes manufacturer uses built-in power, and thus the heat of the power supply and the tube are to be dissipated through an aluminum shell. How to deal with such a great amount of heat is still a problem.
 
Fourthly, competition in LED tube industry is not well-ordered. Since LEDs were introduced into market, there have been thousands of LED tube companies crowding into the market. Suddenly this new born market is in a mess.
 
Some companies just imitate other companies' products without knowing the products well. Of course their products are of low quality. But this industry is so new that there is a lack of standard, and thus these low quality products flow into the market. Other companies make use of media hype, exaggerating the efficiency of LEDs and misleading people who use them.
   
The development of T8 LED tube light is still at the initial stage, so it is inevitable that there are problems impeding the development. The LED tubes manufacturer must work hard to solve these problems so as to boom the LED tubes industry.

Some Facts You Have to Know About LED Fluorescent Lamp
 
Nowadays, copper bathroom sinks have been applied to the decoration in order to enhance the visual appeal of room. Their attractive antique appearance please our eyes and their durability satisfied our functional requirements. Another positive aspect of copper sinks is that they are more sanitary than other materials. Copper is a natural element that contains anti-bacterial substance. It has been proved that a bacterium can live no longer than two hours on copper. Thus, copper sinks have a protective layer on which bacterial and harmful substances will not survive.
 
Although there are many advantages, the leading role in the market of sinks are still occupied by traditional stainless steel and ceramic sinks. Why copper sinks are not so popular as stainless steel and ceramic sinks? Below are some influence factors.
 
High Cost
Copper is an expensive metal, because of this, copper sinks are much more expensive than other kinds of sinks. The price is related closely with the percentage of copper it contains a higher percentage of copper always stands for a higher quality as well as higher price. The quality copper sink contains nearly 100 percent copper. Handcraft is another factor that will effect the price of copper sinks. Hammered bathroom copper sinks which are crafted by skilled artisans will be more valuable. Thus, the price of a high quality copper sink is several times than a stainless steel or ceramic sink.
 
special maintenance
Besides high price, there is another thing people always worry about when purchasing copper sinks. Many people think that keeping copper bathroom sinks shiny and clean is difficult. That is right. Copper sinks always require more maintenance than stainless steel or ceramic sinks.
 
The rustic, aged appearance is the most popular character of copper bathroom sinks. However, the color of the copper will gradually change with time and use. To maintain copper bathroom sinks beautiful, periodically cleanings with a copper clean are needed. When it comes to the method of cleaning your sink, any abrasive scrub should be avoided in order to protect the surface of copper sink from any scratch. Acidic foods, such as tomatoes, oranges and lemons should not be left on copper sinks for a prolonged period of time. Because the acid may produce spots on your sink. Also, it is better to wipe the sink dry after each use. Because hard water contains chemical element which will discolour the copper sink. Regular waxing and polishing could also provide additional protection and enrich the color of copper sinks if you prefer.
 
On the whole, specialized knowledge are necessary for the maintenance of copper bathroom sinks. In contrast, no additional step is needed if you choose to use stainless steel or ceramic sinks, daily cleanings with normal cleaner are enough.
 
However, copper bathroom sinks are indeed healthy and environmentally friendly, and can be matched with all kinds of decoration. With the development of our society, they may become more popular in the future.

Proper Care Keeps Copper Sink Looking Like New
 
In the ancient time, the scaffolding made of wood often brought some troubles. It's not solid enough, or its quality will be affected easily by bad weather. With gradual growth of economy and technology, the steel scaffolding is becoming more popular. While there are still some simple scaffolding made of wood. As a matter of fact, steel scaffolding has more advantages. Moreover, in current situation, many factors boost the comprehensive application of steel scaffolding.
 
1. Reduce the wasting of precious tree.
 
If the scaffolding is chiefly made of wood, what will happen? There will be lack in tree all over the world. Human needs the tree. It will make a better environment for human. If the wood is used as the primary material for scaffolding, we can't breathe the fresh air and we may live in the sand.
 
Instead, using the steel will protect the precious resource, for there is no wasting or cutting. We may adopt the discarded steel as the raw material for scaffolding. This way may bring us benefits in protecting the tree and solving the problem of waste material.
 
2. It's much safer for worker.
 
In fact, working on the scaffolding is a sort of perilous thing. The danger may be caused by improper operation or slimy structure. The slimy structure is the main factor. Can the slimy structure ensure the safety of worker? Of course, it can't. Actually, steel scaffolding is solid or stable enough to bear the load or resist the severe weather like a heavy wind. Wood is a kind of insulator. As long as you have done the insulating measure like using lightning rod, it also ensures staff against danger. But, you'd better avoid working in thunderstorm.

3. Steel scaffolding can be in the form of different structures.
 
Since the steel scaffolding was put into use, it has been designed into several kinds of types, including cuplock scaffolding, gate or bell and spigot scaffolding. The continual change will help improve the security and working efficiency. By comparison, the structure of wooden scaffolding is much simpler. So, the steel scaffolding can satisfy the market demands well. And this demand is a big chance for steel scaffolding suppliers or manufacturers.
 
4. It has a longer lifetime.
 
It's clear that steel scaffolding has longer life than wooden scaffolding. It's because that steel contains some features that wood doesn't have. For instance: steel scaffolding can be used below 250℃; Its better bearing capacity will help last its lifetime.
 
By contrast, the life of wooden scaffolding will be shortened by various reasons, like the water, high temperature or insect.
 
However, the biggest demerit of steel is that it will rust. If you repeatedly do the anti-rust measure, its working life won't be impacted badly.
 
Scaffolding as an important auxiliary device in construction is strict with material or structure. Of all the factors listed above, the steel scaffolding will absolutely replace the wooden scaffolding. Both of construction workers and steel scaffolding manufacturers will benefit a lot
 
Now with the development of technology, LED lamps are becoming more and more popular in the society. For example, they are used as car lights, traffic signal lights, display screens, and even desk lamps. We know that the stroboflash of fluorescent lamps does great harm to our eyes. And in the sense of lifetime, incandescent lamps are less durable than the LED ones. It seems that LED lamps seem to be the best choice for desk work.
 
But are the LED lamps good for our health? The fluorescent lamps emit light which is gentle and the whole process is clear of stroboflash. Is it the same for the LED lamps? According to the tests done by some professional organizations, LED lamps are free of stroboflash, glare, ultraviolet, and infrared.
 
Stroboflash can make man's eyes stay in a state of great stress, which will lead to the visual fatigue and thus the myopia. Different from the traditional lamps that apply alternating current, LED lamps apply the techniques of direct current. This could assure the disappearance of stroboflash. And the fluorescent lamp emits light through stimulating the fluorescent powder by the ultraviolet. While the LED lamps emit light through the current directly, leaving no possibility for the existence of ultraviolet.
 
With so many advantages of LED lamps, why do not buy one? But here is another problem? Since there are different types of these lamps. which type is the best one at the present time, leds t8 or leds t5?
 
Here “t” refers to “tube”, and “8 ”means the perimeter of the tube. So is with the phrase “led t5”. Is there any other difference between the two types of tubes besides the difference in perimeter? The led tube t8 is the common lamp used in homes while led t5 is used in the circumstances of commercial lighting. In today's market, the ballast of led tube t8 is better than that of led t5. And the energy consumption of the former one is much lower, whose energy consumption of itself is only 2 Watts while the energy consumption of the led t5 is about 6 Watts. And the amount of mercury in most t5 tubes is larger than in led t8 tubes. What's more, the caliber of led t5 is smaller, which means the voltage when the lamp is turned on is higher than that of led tube t8. The higher the starting voltage, the higher the temperature is. High temperature tends to lead to the degradation of the lamp and the electric power circuit. In addition, the technology for led t5 is still not so mature at present, so it is suggested to purchase led tube t8 for home uses.
 
With some comparisons above, it is clear that led tube t8 is the best choice for our daily use since there is no harm for our eyes, no danger for potential problems in power supply circuit and there is mature technology for this type of lamps.
