In all inventions bulb invention is undoubtedly the best invention, it makes our lives turned upside down, it is still deeply affect our lives. There are modern lighting in a variety of uses, and can bring us pleasure and visual pleasure, no doubt that the stage lighting, stage lighting in the theater, concerts and other performance of the head. Of course, the beauty of light is also known around the fascinating buildings, like the lighting effects on the tower in Guangzhou, Shanghai Pearl lights at night showing a perfect posture. Of course, the stage lights charm more than that, there are many different uses. Having said this, I believe we all understand, then everyone on the stage lighting price inherent in secret and you know what?

 1, the power supply, the market price is much lower power is not vacuity or use fully rated power 180W led par lamp 108W low power, in fact, consumers are very easy to identify quality of power supply. Good brand power transformers and power above the cylinder volume are relatively large, the overall look more plump texture; arrangement of components and production technology is relatively better, the overall look clean and beautiful. Low power design of insecurity cutting corners, anti-surge, rectifier, steady flow could save the province, but also the province should not be spared, electronic components are also useful for recycled materials, without considering the security and stability of the actual use.

2, the weight of the added value of the product price point of view, in fact, a good product needs to invest some research funding in order to create new products and services. Most of the companies on the market through imitation as had the core technology, which is a price gap.

3, lamp beads, LED lamp beads on the market price varies. Why do some light beads sell so cheap, some lamp beads price difference of a few times, in fact, there are tricky. First, it is certainly the worst materials, such as wire instead of copper wire gold wire, stent use recycled materials or scrap production, something these raw materials, the consumer is not out of judgment, the use of only slowly after exposure come out. Second is to increase the use of power, had normal use of power lamp beads may just 1W, 0.75W, added to the power 3W, beyond the scope of use, the initial brightness is high, but attenuates soon, a few months on the dark. Once again, virtual standard power, is the subject of 3W lamp beads, the real objective is to take 1W or 0.75W to replace lamp beads, or even lower, the consumer generally did not go to the test.

4, radiators, lamp work beads luminous part of the energy is converted to heat, poor heat dissipation, a direct impact on the life of the lamp beads. LED PAR radiator, consumers can identify visually open the lamp housing. Now the market is filled with many small Par thin radiator, and even many businesses in order to price competition does not install the heat sink. As we all know, a lamp power of Par there is no guarantee how good heat sink it? How can we ensure the stable operation for a long time all bright lights beads it?
