The Profoto Acute/D4 Ring Flash Head is soft light source that encircles the lens and supports the camera via the included mount. The head is compatible with Acute and D4 power packs.

Popular with fashion photographers, the Acute/D4 Ring is renowned for its unique catchlights, soft, flat output, nearly shadowless quality of light at a distance and haloed shadows when close to a background. The head employs a safety glass cover for its ozone-free quartz UV-coated flash tube which has a capacity of 2,400W/s and 9,600W/s per minute of continuous firing.

The Acute/D4 Ring ships with a glass safety cover and a 13' power cable. Optional accessories include Softlight, Close-up and WideSoft Reflectors.
