Title: strobist 101: bare bulb/tube w/professional look at a great price
Review: If you want to diffuse the light, this a cheap way to do it (with a more professional look than a cut up plastic tupperware soup bowl from your nearest Chinese fast food restaurant). From stobist.com (Lighting 101: Bare-Tube-Style Lighting), you should use these to bounce the light off walls and not directly on the subject. It's to create the "bare tube" or "bare bulb" effect to light up a room and fill in the shadows in all directions.Note that any diffusion source you use between your flash and subject will likely decrease the amount of light that reaches your subject and may provide a different color cast/tinge to the color of light. You can adjust your exposure compensation and white balance settings as needed.
