Because it can bring a sense of luxury and fashion to the room, the crystal lamp is loved and purchased by many consumers. Although nowadays, more types and more styles of lighting have entered the market, but the crystal lamp is still the first choice in the high-end market.
First, different spaces, different families, different choices
When purchasing a crystal lamp, be sure to choose according to the size of the space and the shape of the lamp. Experts pointed out that according to space requirements, the living room of 20 square meters - 30 square meters should choose a crystal lamp with a diameter of about 1 meter. You can choose according to different rooms: many duplex families mainly use the living room, so they mainly use atmospheric and beautiful ceilings and hanging crystal lamps; some young people or newly married people are in the bedroom. When decorating, you can choose a wall crystal lamp with delicate and warm colors. If you want to install crystal lamps in the kitchen, you can install a hanging crystal lamp that is both energy-saving and warm.
Second, look for the brand to prevent the fish from mixing
Now, the crystal lamps on the market start at 1,000 yuan. Different brands of crystal lamps are similar in appearance. It is worth noting that some unscrupulous manufacturers only make superficial articles. They install high-quality lamp beads on the periphery or obvious parts of the larger crystal lamps, and shoddy the inner layers or hidden places of the lighting. In terms of appearance, they are very similar to some brand-name lighting. For the same appearance, people usually choose lower prices. As everyone knows, those commodities are inferior to them. After a long time, all kinds of problems have been presented. Therefore, people must keep their eyes open when choosing, and choose carefully. Some brand-name crystal lamp manufacturers have a brand logo on every crystal face to ensure their quality and consumers can buy a real brand, so if you buy a brand name, you only need to carefully identify it at the time of purchase. The brand logo is fine.
Third, pay attention to whether the color of the coating is lasting
The life of crystal lamps of different grades is different. Although the difference between high and low grades is not outstanding, the quality difference between high and low grades is obvious. When consumers buy crystal lamps, they must first look at its colorful effects, and then take a look at its gold-plated layer. Generally, high-grade metal fittings are mostly plated with 24K gold. This gold-plated layer will not change color for several years, nor It will rust, and the low-end will not achieve this effect, and it will lose its original color in two or three months. After a period of low-grade crystal light, the color will be dark, the bracket will appear rust, and the high-grade will not change color for two or three years or even longer.
Fourth, choose the crystal light crystal ball is the key
The reason why the crystal lamp can flash is mainly the purity and cutting surface of the crystal ball and the lead content. Therefore, consumers should look at the crystal ball for cracks, bubbles, water ripples and impurities when purchasing. Only crystal clear crystal balls can exert the best optical performance, so that the passing light reflects the magnificent color. On the cutting surface of the crystal ball, it is necessary to see if it is smooth and the edges and corners are clear, so that the crystal ball can achieve the best refraction effect. In terms of lead content, the general high-quality crystal ball will use the whole lead crystal. The lead oxide content is not less than 30%. It is the purest raw material and can emit a sinuous color.

A grade, this type of film is characterized by a neat and uniform appearance, printed electrode grid lines, no broken grid, no surface stains, no leakage, no aluminum package, no hidden cracks, no scratches, no black core, no reverse current, stable electrical performance, and high conversion efficiency
Using solar cell testing equipment to measure and screen, the conversion efficiency, filling factor, and appearance that meet certain standards are first level. Generally, the conversion efficiency, filling factor, and appearance of first level are better than those of level B
The level of solar panels can be divided into first level, second level, third level, and fourth level, and the first level components can be divided into first level+and first level - two levels. The second level is also the same, and the cost difference between different levels of solar panels is also very large.
