Abstract: A baffle mountable on the tube of a fluorescent lamp which in the absence of the baffle yields a harsh and glaring light. The baffle is formed of a long strip of fabric material having a row of holes therein through which the tube is threaded to cause the strip to assume the shape of an undulating shade which conceals the lamp. The felt strip is preferably constituted by a pressed, non-woven felt fabric whose fibers are reflective of light and absorbent of sound or a similar flexible absorptive material. Light rays emitted by the lamp are intercepted and dispersed by the shade, thereby diffusing the light and softening the illumination. Ambient sounds impinging on the undulating shade are absorbed thereby to reduce the noise in the room in which the lamp is installed.
