At first glance, fake opal lamps are generally rough in workmanship and have many burrs at the corners. The manufacturer's logo on the opal lamp is vague or even absent. The installed interface is not so seamless. Then look at the transparent surface of the opal lamp. The glass surface of fake parts is generally opaque, so the bulb and reflector inside can't be seen clearly, and there may be impurities inside. Authentic opal lamps do not have such problems. False lights are generally not correct in color, light or heavy in color, and some fake products will fade. There must be a quality problem with the lamp in this situation.

Second, as long as you turn on the light, you can see the inherent quality of opal lamps. Generally, the light emitted by fake opal lamps will be divergent and irregular due to the poor reflector. The same two lamps may have different brightness. Authentic products will not have such problems. Third, look at assembly. Although the grinding tools of fake opal lamps are made by imitating real opal lamps, there are still some differences, so they will not stick together after assembly. 4 Comparison: Because some fake parts are still highly simulated, it is still difficult to distinguish true from false by the above methods. At this time, you need to compare the opal lamps removed from your home to distinguish between true and false. Only by comparison can you distinguish the product identification and material of fake parts.

Finally, it is not enough for optics to meet the above points. It is most important to choose a reputable dealer. The simulation degree of some chess pieces is unbelievable, so choose a good merchant to prevent being cheated. Of course, maybe their price will be more expensive.
