With its high intensity #2 reflector and prismatic glass, the tiny focusable Pro-light is more efficient than a Fresnel of equal wattage, yet it gives an exquisite even light, with Fresnel-like shadow quality. It can be used as a low-level key or accent light, fill light (with diffusion), or backlight. In addition to a wide variety of customizing accessories, its versatility can be increased by adding a DC adapter cable & swapping its bulb for use as a camera-top fixture.
