First of all, we can be judged from the lamp body itself, ultra-thin panel lamp is close to the panel and rear cover, is a state of seal.So that it can be effective moistureproof, insect-resistant, waterproof effect.Ultra-thin panel lamp shell are generally use high material of metal shell, long service life.But if is the ultrathin panel light quality is bad, the panel and integrated design, the fuselage is not only panel is metal, the fuselage or plastic material, although this panel lamp is very light, but not only the cooling effect is not good, and never use time is very long.

Second, ultra-thin panel lights a part of the material is also very important.Good quality ultra-thin panel lights are used in anti-oxidation aluminum alloy material, so whether in any environment can be normal use, and also won't appear rusty.But some of the bad quality of ultra-thin panel lights, their body use made of iron, it will be easy to rust in humid environment, and there will be the potential risk of leakage.If you take a piece of magnet can suck up, that is made of iron.
