Nowadays, there are various LED linear lamp manufacturers on the market. Many manufacturers favor the advantages of their own line lights, such as high cost performance, low price, and long life. There are also some high-priced "brand-name goods". How do you distinguish the quality of line lights? I will take everyone to master how to distinguish the quality of LED linear lights.

The first method: look at the super glue: because the super glue material is very poor, the line lights will become more severely yellow after one year. The fake and inferior super glue in the name of moisture-proof PU glue in the sales market has poor moisture-proof properties and is easy to light yellow and darken. The price of general moisture-proof PU glue is very large, and most of the price is more than double the price.

The second method: look at the aluminum alloy profile: the thin aluminum profile is very easy to deform. In the selection of aluminum profiles for linear lamps, manufacturers are the first to consider heat rejection characteristics. In all normal circumstances, when choosing the aluminum profile of the lighting fixture, consider the actual effect of the heat dissipation of the lighting fixture, the selection of the appropriate thickness of the aluminum profile. In addition, if the aluminum raw material of the linear lamp is very thin, the thinner the aluminum raw material, the worse the heat dissipation. It is very easy to be extruded and deformed during the whole process of installation and transportation! In order to be more cost-effective, manufacturers must manipulate the raw materials used very well.

The third method: look at the LED lamp beads: in the field, there are only a few well-known packaging manufacturers, such as: Cree-Preh-Nichia-Taiwan Epistar, etc., but you can distinguish the processing chips of this well-known brand you have obtained ? There are some ruthless line lamp manufacturers whose prices advertise how good the raw materials are. They use low-end processing chips to counterfeit processing chips of major brands, but the basic law of price has always existed, how? Is it possible to buy a good product in a cost-effective way? Consumers also take their own humiliation and are willing to be deceived. I and I are also drunk. Some well-known brands of LED lamp beads in China have been tested and improved for many years. Their processing technology and characteristics are also very skilled and stable. According to your cost and high performance-price ratio, you can also choose some well-known brands in China, such as Sanan processing chips are very good.

The fourth method: the choice of circuit boards: Will solar cells be stronger than fiberglass boards? Indeed, high-quality linear lamps are the key to the circuit board of the lamp source. Is the fiberglass board always marked with fake and inferior logos? This is not the case. I used to think that fiberglass board products are not high-quality products. After experiencing the expressions of professional and technical personnel, because I have grasped the pros and cons of fiberglass board. It can even be stronger than the quality of solar cells. If it is stable, whether it is solar cells or glass fiber boards, they are all good circuit boards.

The fifth method: Look at the waterproof plug: The LED sales market is indeed very large. At the beginning of this year, customers will ask once every year: "Are there new prices in 2020?" Some manufacturers will reduce raw materials based on this type of work pressure. , But there are also some manufacturers who reduce profits to keep their original customers. There are also cost-effective waterproof plugs, but relatively speaking, the cable diameter is small and the conductivity is poor, and the moisture resistance is weak. It is very easy for water seepage to cause power failure. Most of the square-head four-pin plugs are also very good. Although its price is higher, the overall reliability can be 99% moisture-proof, and 1% may not be plugged in.
