Wescott's Strobelite 3 Light Educational Kit is a great way to take studio quality lighting on the road. With a combined 900 effective watt/seconds, you have more than enough power for portraits, groups or product work. The kit is built around the Strobelite flash head which offers 300 effective watt/seconds of power with stepless variability from 25% to full power, as well as fast, 2.5 second recycle times and built-in optical slaves to avoid a tangle of PC cords. The 100W modeling lamp allows you to pre-visualize the light falling on your subject before triggering your Strobelite. Convenience features include a ready light and audible beep to insure that your lights are powered up and ready for action. The kit includes two 43" white translucent umbrellas, two 7.5' light stands and a carry case. A Backlight Stand that's compact enough to hide behind your subject is also included. A unique aspect of this kit is the inclusion of a light-placement floor mat and dedicated Educational DVD that walks you through lighting techniques and setups.
