COSMETIC ISSUE (Does Not Affect Operation)

Strobe Mount and 18650 Battery not included


The Marelux Smart Optical Flash Tube (SOFT) is a revolutionary, new high-end snoot for underwater macro photography. It can be adapted to most modern strobes and features a built-in aiming light (that can shut off automatically when the strobe is fired), an adjustable iris/aperture, and a quick release mount. The focus point is 170mm from end of the tube. The light diameter can be adjusted from 2mm to 60mm.

Key Features:

  • Aiming Light - The Smart Optical Flash Tube comes with an 180 lumen aiming light which greatly helps you position your strobe to perfectly illuminate your subject. It also features an auto shut off when the strobe is fired.
  • Aperture Adjustment -  The aperture can be adjusted to your liking with the external dial.
  • Battery - It uses the standard 18650 battery (length 67mm) which can power the light for 16hrs continuously.
  • Carrying Case -  The SOFT comes with a carrying case to protect it from dust, dirt & scratches when traveling.
