Light apparatus and systems to produce a diffused light source for stage, studio, motion picture and still photography. A tube constructed from selected proportions of diffusion material and reflective material is secured at opposite ends to light reflectors or light reflecting umbrellas with light sources. The light generated by the light sources is reflected off of the reflectors and is also reflected off of the reflective material of the tube to produce a desirable light dispersion pattern across the length of the diffusion material of the tube.
