How to distinguish the quality of LED line lights?

There are many styles of LED linear lights. Many manufacturers praise their own linear lights for their good quality, low price, long life, etc. There are also some expensive "brand products".

First, look at aluminum:

        The ultra-thin aluminum material is easy to change. When selecting the aluminum material of the line light, the regular manufacturers will first consider whether the heat dissipation performance is good. Do you think the thicker the aluminum material, the better? If the aluminum material is not easy to deform, If the heat dissipation is good, you must choose a moderate thickness. It cannot be said that the thicker the aluminum material, the better. In addition, if the aluminum material of the linear light is thinner, is the heat dissipation better? The thinner the aluminum material, the worse the heat dissipation. It is easy to be squeezed and deformed, so cutting corners is not a good thing! Another issue is the cost performance. If you want to be cost-effective, the manufacturer must control the materials well.



Second, look at the selection of circuit boards:

        Is the aluminum substrate definitely better than the fiberglass board? It is true that good-quality line lights mostly use aluminum substrates as the circuit boards for the light source. Has the fiberglass board been labeled as inferior all the time? Fiberglass board is also good or bad, and it can even be better than the quality of the aluminum board. circuit board.



Third, look at the glue:

        The serious yellowing phenomenon of LED line lights after one year is because the glue materials are 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 prone to yellowing and darkening. The same It is far from the price of normal waterproof PU glue, basically the price difference is more than double.



Fourth, look at the waterproof plug:

        The LED market is huge. Every year at the beginning of the year, customers will ask: "Is there a new price this year?" Under this pressure, some manufacturers will reduce their materials a little bit, but some manufacturers will lower their profits. To maintain the original customers, there are also cheap waterproof plugs, but relatively speaking, they are not good at conducting electricity, and their waterproof performance is poor, and they are prone to water leakage and leakage. Basically, the square-headed four-pin plug is also very good, although its price is higher. , but the overall stability can reach 99% waterproof, and that 1% may not be plugged in tightly.
