The earliest use of 4 x 8 aluminum sheet was in lamps, especially commercial lighting. Such as well-known grille lights, bracket lights, outdoor lights, flood lights, spotlights, aquarium lights, etc.
The main function of the specular aluminum reflector is to reflect from the inside of the lamp, often called a reflector. The role of the reflector in the lamp is very critical, and the luminous efficiency can be increased by more than 60%.

It is recommended to pay attention to the surface damage of processing mechanical fragments.
