There are many styles of LED linear lights. Many manufacturers admire the quality, low price and long life of the linear lights made by themselves. There are also some high-priced "brand goods". How do we distinguish the quality of linear lights?
The first trick is to look at the glue:
The line lamp has serious yellowing after 1 year because the glue is too poor. There are many inferior glues sold in the name of waterproof PU glue on the market, which have poor waterproof performance and are easy to send. The yellow becomes darker, and the price of normal waterproof PU glue is far different from that of normal waterproof PU glue. Basically, the price is more than doubled.
The second trick is to look at aluminum:
Ultra-thin aluminum is easy to change. In the selection of aluminum for linear lamps, regular manufacturers will first consider whether the heat dissipation performance is good or not. Do you think that the thicker the aluminum, the better? Yes, if you want the aluminum material to be resistant to deformation and good heat dissipation, you must choose a moderate thickness. It cannot be said that the thicker the aluminum material is, the better. In addition, if the aluminum material of the linear lamp is thinner, is the heat dissipation better? What? NO! The thinner the aluminum, the worse the heat dissipation, and it is easy to squeeze and deform during installation, so it is not necessary to cut corners! Another problem is cost performance. If you want a high cost performance, the manufacturer must control the materials used quite well.
The third trick is to look at the lamp bead components:
In the industry, there are only a few famous packaging manufacturers, such as Cree-Preh-Nichia-Taiwan Epistar, etc., but you can tell if it is you Did you get the brand-name chips? There are some unscrupulous line lamp manufacturers whose quotations indicate how good the raw materials are. They take a few cents of chips to pretend to be big-brand chips, but the price law has always existed. How could it be possible? Cheaper will buy good products? Customers are also deceived by themselves, willing to be deceived. There are some domestic lamp beads brands that have been tested and improved for many years. Their craftsmanship and performance are also very proficient and stable. According to your project cost, you can also choose some domestic better brands.
The fourth trick depends on the choice of circuit board:
Will the aluminum substrate be better than the fiberglass board? It is true that the quality of the line lights is mostly used as the circuit board of the light source. Is the fiberglass board always labeled with inferior quality? This is not true. I used to think that the product of fiberglass board is not a high-quality product. After the explanation by the technician, I also understand that the fiberglass board is also good or bad. It can even be better than the quality of the aluminum substrate, as long as it is stable, whether it is an aluminum substrate or a glass fiber board, they are all good circuit boards.
The fifth trick is to look at waterproof plugs:
The LED market is really big, and customers will consult once a year: "Are there any new prices this year?" Some manufacturers will reduce their materials because of this pressure, but some manufacturers will reduce their profits. Lowered to maintain the original customers, waterproof plugs are also cheap, but relatively speaking, the electrical conductivity is not good, and the waterproof performance is poor, and it is easy for water to enter and cause leakage.
