The SP Commercial Lighitng Kit is a 2-monolight kit providing a total of 370 watt seconds of power, good enough for a small portrait set or as an augmentation of a larger lighting scheme. You'll get the 2 SP150 monolights, the SP100 slave-only flash, 90" light stands, an umbrella for softening the light, a sync cord, and a foam-lined case.
The 4-tube SP150 monolights have a switchable modeling light and variable power control (1/1, 1/2, 1/4, 1/8, or 1/16th power levels), with a recycling time of under 5 seconds at full throttle. The SPS100 slave flash is a compact and powerful flash that's easy to use, with a built-in slave.
The brackets included with the lights allow you to mount them to the included stands, but you can also mount them upon a standard 1/4"-20 tripod thread.
