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 linear lights? Good or bad, where should we analyze it?
Analyze the quality of line lights from the basic five points
First type
Look at the glue: the first line lamp has such a serious yellowing phenomenon after 1 year because the glue material 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 it is far from the normal waterproof PU glue. Basically, the price is more than doubled.
Second type
Look at aluminum: ultra-thin aluminum is easy to change. In the selection of aluminum for linear lights, regular manufacturers will first consider whether the heat dissipation performance is good or not. Do you think that the thicker the aluminum, the better? Actually otherwise, the thicker the foundation you put on the makeup, the better it looks? Definitely not. 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, does it dissipate heat? The better? NO! The thinner the aluminum, the worse the heat dissipation, and it is easy to squeeze and deform during installation, so cutting corners is not necessary! The other is a cost-effective issue. If you want to be cost-effective, manufacturers must control the materials they use fairly well.
Third type
Look at the lamp bead components: In the industry, there are some line lamp manufacturers who have buried their conscience. Their quotations advertise how good the raw materials are. They take a few cents of chips to sell them as big-brand chips, but the price law has always existed. , How is it possible to buy good goods at a low price? Customers also deceive themselves and are 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.
Fourth type
Look at the selection of the circuit board: will the aluminum substrate be better than the fiberglass board? It is true that the high-quality linear lights mostly use aluminum substrates as the circuit boards of the light source. Has the fiberglass board been labeled with poor quality all the time? This is not true. Fiberglass boards are also good or bad, and can even be better than aluminum substrates. As long as they perform stably, whether they are aluminum substrates or fiberglass boards, they are all good circuit boards.
Fifth type
Look at the waterproof plug: The LED market is really big. Every year, customers will consult once: "Is there a new price this year?" Some manufacturers are forced to reduce the material because of this pressure, but some manufacturers The profit is lowered to maintain the original customers. There are also cheap waterproof plugs, but relatively speaking, they are not conductive, and have poor waterproof performance. They are easy to leak and cause leakage. Basically, the square-head four-pin plug is also very good. The price is higher, but the overall stability can reach 99% waterproof, that 1% may not be tightly plugged.
