With the Top Light Puk colour filters, numerous light-colour effects can be created. They are either simply inserted between lens and housing or glass and housing. These accessories are available in red, yellow, green, magenta and blue. Colour filters can be inserted into the top or bottom of the Puk lamp. It is also possible to combine different colour filters in one lamp to create individual colour effects. A lamp with a glass insert diffuses the light more than a lamp with a lens. These colour filters are suitable for the following lamps: Puk Wall, Puk Wall +, Puk Fix, Puk Fix +, Puk Mirror, Puk Mirror +, Puk Move, Puk One, Puk One 2, Puk Plus, Puk Turn and Puk Choice Mirror/Wall.
