This diffuser family utilizes a circular drum design to give designers maximum light output in a classic shape. The diffusers are suitable for either ceiling or wall mounts in commercial, residential, or hospitality applications. The classic drum design has been used in lighting for over 40 years. Now designers can use this time-proven design with energy efficient circline and compact fluorescent lamps. The diffusers are available in smooth injection molded white acrylic or polycarbonate, or clear prismatic injection molded acrylic and polycarbonate.
