The Photoflex Starlite QL gives you the results you've been looking for in a hot light. Uniquely designed for use with a softbox, the long bulb extends directly into the center of the box, reflecting light evenly off all four sides. This maximizes both output and efficiency. The Starlite QL is a "flicker-free" light source, which provides a light quality that is soft, beautiful and natural looking, yet powerful enough for the demands of video or digital photography. Lamps must be purchased separately.
