The AD-S200 flash Stick, features a cylindrical design, with a transparent 360° flash tube. This allows the flash to emit light in all, directions, producing even lighting, with very little light fall-off. Due to its compact and slim profile, the AD-S200 flash head can be put into tight spaces that are either impractical or impossible to get a regular flash head with modifier into, and still have the ability to illuminate the entire space. The AD-S200 also comes with a set of barn doors, which enable you to control the spread of light, for times when full 360° illumination is not required or is undesirable. Perfect for Fashion, beauty, portrait, and lifestyle photographers, as well as interior or architectural photographers.
