(Barndoors, bulb and stand sold separately.)With its high intensity #2 Reflector & Prismatic Glass, the tiny focusable Pro-light is more efficient than a mini-fresnel of equal wattage. It gives an exquisite even light, with fresnel-like shadow quality, evenly dispersed flood, and a uniform spot with significant barndoor cut.Used with today's more light sensitive digital cameras & filmstocks, it's compact size makes it the perfect low-level key or accent light, fill light (with diffusion), or back-light for interviews & other small shooting-areas. In addition to a wide variety of customizing & control accessories, its versatility can be increased by adding a DC adapter cable & swapping its bulb for battery operation. Replace the Prismatic Glass with Clear Safety Glass for a non-focusing super-spot in special use situations.
