There are a wide variety of LED linear lights. Many manufacturers admire the quality, low price, long life, etc. of their own linear lights. There are also some high-priced "brand goods". How do we distinguish the quality of linear lights?
1. 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. Do you think that the thicker the aluminum, the better? If the aluminum wants to be resistant to deformation, If the heat dissipation is good, you must choose a moderate thickness. It cannot be said that the thicker the aluminum material is, the better, and if the aluminum material of the line lamp is thinner, is the heat dissipation better? The thinner the aluminum material, the worse the heat dissipation, installation It is easy to squeeze and deform, so cutting corners is not necessary! Another issue is cost-effective. If you want to be cost-effective, manufacturers must control the materials used quite well.
2. Look at the selection of circuit boards:
Will the aluminum substrate be better than the fiberglass board? It is true that the line lights of good quality are mostly used as the circuit board of the light source. Is the fiberglass board always labeled with inferior quality? Fiberglass boards are also good or bad, even better than the quality of the aluminum substrate, as long as they are stable, whether it is aluminum substrate or fiberglass board, they are all good Circuit board.
Three, look at the glue:
The serious yellowing of LED linear lights occurred after 1 year because of the poor glue material. There are many inferior glues sold under the name of waterproof PU glue on the market. They have poor waterproof performance and are easy to turn yellow and dark. The same It is far from the price of normal waterproof PU glue, basically the price difference is more than doubled.
4. Look at the waterproof plug:
The LED market is really big, and every year at the beginning of the year, customers will consult once: "Are there any new prices this year?" Some manufacturers are forced to reduce their materials because of this pressure, but some manufacturers lower their profits. To maintain the original customers, there are also cheap waterproof plugs, but relatively speaking, they are not conductive, and have poor waterproof performance, which is easy to enter water and cause leakage. Basically, the square-head four-pin plug is also very good, although its price is higher. , But the overall stability can reach 99% waterproof, that 1% may not be tightly inserted.
