Learn three tricks to easily distinguish the pros and cons of LED wall washer. Let you easily buy high-quality products.

The first trick: look at the glue: If the LED linear lamp has serious yellowing after 1 year, it is 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. It is easy to turn yellow and dark, and the price of it is far from the 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. Regarding the selection of aluminum for LED 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? Otherwise, the thicker the foundation for your makeup, the better it looks? Certainly not. If you want aluminum to be resistant to deformation and good heat dissipation, you must choose a moderate thickness. You can't say that you want the thicker the aluminum. Well, if the aluminum of the linear lamp is thinner, is the heat dissipation better? NO! The thinner the aluminum is, the worse the heat dissipation is, and it is easy to be squeezed and deformed during installation.

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 this is you Did you get the brand-name chips? Some unscrupulous LED linear lamp manufacturers advertised how good the raw materials are. They took a few cents of chips to pretend to be big-brand chips, but the price law has always existed, how? Maybe you can buy good products cheaply?
