What is the projector lamp selection?
There are many types of projector bulbs on the market today, which can be roughly classified into the following six categories according to the place of production.
The first category is the original light bulb introduced by the projector manufacturer. Its obvious mark is the packaging of the manufacturer's logo and the special lighthouse, which is called the "original package."
Features: Its quality and service life have been rigorously tested. The quality of the product is absolutely guaranteed. It can basically reach the average usage time stated by the projector manufacturer. Users are advised to use this type of bulb as their first choice. However, due to the increase of profits at the channel level, prices are generally high. And very few sources of goods, it is difficult to buy. 
The second category is light bulbs produced by projection lamp manufacturers that flow from the other channels to the market, such as PHILIPS and OSRAM.
Features: Some of the so-called "original light bulbs" are manufacturers of defective or projector manufacturers test light bulbs, it is difficult to easily identify the appearance, the life is relatively short, in the purchase must pay attention to avoid being deceived.
The third category is Taiwan light bulbs produced by Taiwanese manufacturers such as Guo Qiao. .
Its characteristics are: can replace U HP, VIPR and other light bulbs, but the service life is much less than the original light bulb, usually in about 500 hours; its single light bulb offer lower, but the average cost is very high, are at 3 yuan / hour, More than 1-2 yuan more than the original light bulb. Due to the short use time, the brightness is attenuated quickly, and the frequency of replacement is frequent, causing inconvenience to the user. Users are advised to buy this type of lamp with caution. 
The fourth category is homemade bulbs. There are currently three major manufacturers in Wuhan China Optical Valley Huameng Optoelectronics, Dandong Xinya, and Nanhai Snow Wright (formerly Nanhai Huaxing) that can produce replacement U HP lamps.
Characteristics: It is the lamp life is not long, and the light bulb is similar to the Taiwanese. It is easy to extinguish the unknown cause during use. However, the homemade bulbs were printed by U.S. Hewlett-Packard as original U-bulbs.
The fifth major category is the modified light bulb. For example, using VIP into U HP bulbs, HSCR into U HP bulbs, UMPRD modified into NSH bulbs.
The sixth major category is old bulbs or counterfeit bulbs, such as illicit merchants' wicks and counterfeit projector bulbs in Japan, Taiwan, and domestic coastal areas.
Its characteristics are: rough work, short life, poor compatibility, the use of the process will be extinguished for unknown reasons. Unscrupulous merchants generally use wicks or old-made wicks that have been removed from old bubbly bulbs and are sold on light cups. Currently Sony, Sharp, EPSON, BenQ, etc. are mostly wicked light bulbs, it is recommended that users carefully identify when buying, be careful. 
According to different materials can be divided into metal halogen lamp, UHP lamp, UHE bulb, led bulb.
1, the advantages of metal halide bulbs are cheap, shortcomings are short half-life, generally less than 1000 hours use will be reduced to half the original brightness, and heat is high, the projector cooling system requirements are high, not suitable for long-term projection use .
2, UHP bulbs are (Ultra High Performance), belongs to ultra-high pressure mercury bulb, its long life, generally nominal 6000 hours, the longest even nominal 12,000 hours, the cumulative working hours after 4000 hours will not appear brightness Obvious attenuation. At the same time UHP bulbs are also an ideal cold light source, but due to the high price, they are generally used in engineering projectors.
3. UHE bulbs are also a kind of cold light source. UHE bulbs are the ideal light sources widely used in mid-range projectors. The advantage is that the price is moderate, and the brightness is hardly attenuated until 4000 hours have elapsed.
4, led light bulbs. LEDs are also called light emitting diodes. This technology has long been used in display and lighting applications. Its main body is an electroluminescent semiconducting material. A positive voltage is applied to both ends of the electroluminescent material. The current flows from the LED anode to the cathode. The semiconductor crystal emits light of different colors from ultraviolet to infrared. The stronger the current, the stronger the light emission. . Long service life, energy saving and environmental protection. Compact, portable, feature-rich, and powerful interoperability with portable digital devices.

How much is the projector lamp?
As we all know, the projector's light bulb has a time of use. Once the light bulb is broken, even if the projector is good, it cannot be used again. If the projector lamp is not damaged during the warranty period, it can be repaired and replaced free of charge. If it is not under the warranty period, it depends on what model and brand you are, and it will cost hundreds of pieces. If you are expensive, it may be more than 3,000.
