Turn on the strobe light by plugging the power cord into the nearest electrical outlet. The strobe will begin to flash one time per second.
Locate the strobe light speed-adjustment knob on the back on the light's frame. Turn the speed adjustment knob clockwise to increase the speed of the flash. This setting is best used to give the appearance of slow motion.
Turn the speed-adjustment knob counterclockwise to slow down the flash speed to allow more time in between flashes. This setting is used when imitating a flash of lightning or an explosion.
