When fully extended, the MagBeam gives you super-focused light with a hard edge, similar to a stage spotlight. Collapse the MagBeam down one or two stages to create a wider beam pattern while retaining the beautiful shape and crisp edges.
Its like having a Hollywood-style fresnel spotlight that fits in your pocket..
2 to 3 stops brighter than your bare flash.
Sometimes photographers need more "juice" from their speedlites, and the MagBeam is up for the job. It's designed to give you up to 2 to 3 effective extra stops of useable light.
This means more light at a greater distance, and your flash recycles 4 times as fast. Ya, its a big deal.
