Abstract
A prefinished curved reflector suitable for use in recessed lighting, downlighting, head lamps, and tail lamps is made from metal sheet, preferably an aluminum alloy sheet. An outer surface of the metal sheet is either anodized, laminated, or polymer coated to provide desired appearance and performance. Surprisingly, the metal sheet retains its reflectivity and resistance to corrosion even after deformation into a curved reflector.
