The first trick is to look at the glue: the first line light has such serious yellowing phenomenon after one year because the glue is too poor. There are many inferior glues sold in the name of waterproof PU glue on the market. They have poor waterproof performance and are easy to turn yellow and dark. Similarly, the price of it is far different from that of normal waterproof PU glue, basically more than double the price.
The second trick is to look at the aluminum: ultra-thin aluminum is easy to deform. In the selection of aluminum for line lights, regular manufacturers will first consider whether the heat dissipation performance is good. Do you think the thicker the aluminum, the better? In fact, it is not. The thicker the foundation, the better you look when you put on makeup? Definitely not. If aluminum is not easy to deform and has good heat dissipation, it must be selected with a moderate thickness. It cannot be said that the thicker the aluminum, the better. In addition, if the aluminum of the line light is thinner, will the heat dissipation be better? NO! The thinner the aluminum, the worse the heat dissipation. It is easy to be squeezed and deformed during installation, so cutting corners is not allowed! Another is the issue of cost performance. If you want a high cost performance, the materials used by the manufacturer must be well controlled.
The third trick is to look at the lamp bead components: In the industry, there are only a few well-known packaging manufacturers, such as Cree - Bridgelux - Nichia - Taiwan Jingyuan, etc., but can you tell whether this is the brand chip you got? Some unscrupulous linear light manufacturers boast about how good the raw materials are in their quotations, and use chips worth a few cents to pretend to be big-name chips, but the price law actually exists all the time. How can you buy good products at a low price? Customers are also deceiving themselves and are willing to be deceived. The editor is also drunk. Some domestic lamp bead brands have been tested and improved for many years. Their craftsmanship and performance are also very mature and stable. According to your project cost, you can also choose some better domestic brands, such as Sanan, which is also good.
The fourth trick is to look at the selection of circuit boards: Is aluminum substrate definitely better than fiberglass board? Indeed, most of the high-end linear lights use aluminum substrates as circuit boards for light sources. Has fiberglass board always been labeled as inferior? This is not true. I used to think that fiberglass products were not high-end products. Later, after the technicians explained, I also understood that fiberglass can be good or bad, and can even be better than aluminum substrates. As long as they perform stably, whether they are aluminum substrates or fiberglass, they are all good circuit boards.
The fifth trick is to look at the waterproof plug: the LED market is really big. At the beginning of each year, customers will ask once: "Is there a new price this year?" Some manufacturers will reduce the material a little under this pressure, but some manufacturers will lower their profits to maintain existing customers. There are also cheap waterproof plugs, but they are relatively poor in conductivity and waterproof performance. They are easy to get water in and cause leakage. Basically, the square head four-core plug is also very good. Although its price is high, the overall stability can reach 99% waterproof, and that 1% may not be plugged in tightly.
