Behind the pure and luxurious appearance, how many hidden secrets are hidden?
Most crystal lamps are made of artificial crystal
Currently, the crystal lamps sold on the market are divided into three levels. The best imported crystal lamps use high-grade artificial crystals (not natural crystals, of course, natural crystals are too expensive, and its transparency is also high. Less than the lighting requirements), such as Swarovski has produced semi-finished crystals, sold in bulk to other manufacturers to do crystal lamps, these crystals and counters crystal jewelry quality refraction transparency are the same, the crystal lamp made is also very beautiful 璀璨The price is generally above 10,000 yuan.
From the point of material technology, crystal lamps can be divided into heavy lead crystal blowing chandelier, low lead crystal blown chandelier, crystal glass mid-range chandelier, crystal glass pendant chandelier, crystal glass die-casting cutting chandelier, crystal glass bar chandelier and so on. Crystals can be randomly cut into various shapes and can realize numerous ways of arrangement and combination, so crystal lamps can flexibly change various shapes. More common anchor, disc and spiral hanging shape.
Yan Ming, head of Suming Lighting's Nanjing market, said that the crystal lamps on the market are mostly made of crystal. The materials used in the crystals are different, and the effects are also different. The crystal lamps of good quality are made of high-tech materials, and some crystal lamps that are filled with fine crystals even use plastic as the material of the crystal, and the light and shadow effect is naturally poor. “Crystal lamps are mostly aimed at relatively high-end customers, so the prices of crystal lamps in the market are relatively high, mostly ranging from several thousand dollars to more than ten million. If consumers see a few hundred dollars of crystal lamps, Choose carefully."
Must pay attention!
Thousand yuan below the "crystal lamp" to prevent false
"Man-made crystal parts are also divided into domestic and imported, the purity is different, the quality is not the same, the price is not the same." Red Star Meikailong light Matt supermarket also said that the domestic crystal belongs to the second level, now the general price In the range of a few thousand dollars to more than 10,000 yuan, it is mainly determined based on the technology of cutting and the components of the process. There are glass crystal lamps that are less than one thousand yuan in price and polished and die-cast. Whether they are crisp or transparent, they are much worse than high-grade imported or domestically-made crystal lamps.
When it comes to the difference between crystal and glass, the industry stated that although their components are all silicon dioxide, crystal is a crystal of silicon dioxide, and glass only contains a mixture of silica in the molten state. Their hardness is different, and the refractive index of light is naturally different. A small pineapple-shaped glass costs only a few cents, and the same size of lead-based synthetic crystal will cost between a dozen and a few hundred dollars.
“Because ordinary consumers can hardly distinguish heavy lead crystals, low-lead crystals, crystal glasses, and lamps of similar styles, materials may vary widely. Coupled with the lack of uniform pricing, many unscrupulous merchants use discounted prices to attract customers’ attention.
If it is pure and inexpensive, buy a fake plastic “crystal lampâ€, even if it is sold well, if the wind drifts, the lighting of plastic products will “floatâ€, not calm and less full and transparent. Under long-term lighting, it is also easy to produce harmful substances; if you purchase crystal lighting that is not properly proportioned with tin oxide or is simply a glass product, the visual sensation of refracted light is certainly not as good as that of a crystal lamp. Lamp holders and support rods are easy to issue after the sale.
A lot of comparison!
Artificial crystal "matching degree" determines the quality
Industry insiders also reminded consumers that crystals are chemically synthesized from glass and metallic lead. Among them, the role of lead is to make the glass more light transmissive. When the proportion of glass containing lead oxide is more than 24% and the refractive index reaches 1.545, it can be called crystal. "If the ratio is not good, or unqualified, crystal products will release lead, over time will cause harm to the human body, therefore, when buying crystal lamps should try to choose brand lamps, so as to avoid unscrupulous businessmen shoddy. "Consumers can also ask for the difference between crystal glass lamps and leaded artificial crystal lamps or even plastic lamps in some specialty brand stores. Highly reputable branded merchants generally display their differences on the spot.
In addition, the transportation, installation, and later maintenance of crystal lamps are also troublesome. Hexi Decoration City Lighting Factory official said: "Because of the relatively high installation height of the crystal lamp, coupled with its complex shape, the brand lighting shop will arrange for someone to be responsible for transportation and installation, after-sales service is also guaranteed, regular home maintenance can also provide regular, Avoid damaging lamps or falling."
