Smith-Victor A10UL Adapta-Lights have been a mainstay for photographers for decades. Now they're gaining a new popularity, as the next generation of photographers realizes you don't need expensive, high-tech lighting to create great lighting effects. The A10UL Adapta-Lights feature 660-watt medium screw-base phenolic sockets, 10ft. 2-wire cords, 5/8-inch mounts and new UM-6 umbrella mounts. The reflectors now have an umbrella punch-out, and are hand-spun and chemically etched to maximize light output. The exteriors have a photographic black, baked-on enamel finish. The insulated handles allow for heat-free adjustment while in use. Lamps sold separately.
