Beginning with just 2 lights and 2 umbrellas is the perfect way to learn about studio lighting. If you're ready to begin working with strobes, this SP Systems Basic 2-Light Studio Portrait Kit can get you headed in the right direction: 2 flashes, 2 light stands, 2 umbrellas and 2 swivel/umbrella brackets give you all you need for a wide variety of photography. Portraits, still-lifes, interiors and more can be effectively handled with a simple 2-light set-up like this. Each flash has a guide number of 92, a 60W modeling light, and a power ratio switch, to change the power to 1/4, 1/2 or full. It also features a built-in optical slave, which can "see" the light from another flash, and fire instantaneously. A carry case is included for storage and transportation of the kit. Supplied for use with 120VAC.
