Mares EOS Strobe
450-Lumen Rechargeable Dive Strobe with 360° Visibility
Stay easier to spot during night dives, low-visibility conditions, and underwater signaling situations.
The Mares EOS Strobe is a rechargeable underwater marker and signaling light designed to make a diver easier to identify during night dives, low-light conditions, and other situations where visibility matters. Its 450-lumen LED, diffused 360° output, and flashing or steady-light modes make it a practical addition to a diver's equipment.
For underwater photographers, this is primarily a diver-visibility accessory, not a camera flash or high-output video light. It can be carried alongside a camera system without requiring an electrical or optical connection to the housing.
Night diving, low-visibility diving, dive guides, and underwater photographers carrying additional visibility equipment.
360° diffused visibility rather than a narrow, directional flashlight beam.
Can be carried independently of most underwater camera systems; no TTL or fiber-optic connection.
Rechargeable power, rotary magnetic control, and wider stated visibility.
Not a synchronized photographic strobe and not a substitute for a primary dive light.

Mares EOS Strobe Frequently Asked Questions
Is the Mares EOS Strobe compatible with my underwater camera housing?
The light operates independently of your camera housing, so it can be carried alongside most camera systems. It does not connect to TTL, fiber-optic, or electronic flash triggering systems.
Can I use the Mares EOS Strobe to take underwater photographs?
It is a diver signaling light, not a photographic flash. For synchronized still photography or consistent video lighting, choose a dedicated underwater photo strobe or video light.
How long does the Mares EOS Strobe battery last?
Published specifications list 5–25 hours depending on the operating mode. Runtime can vary with battery condition and use.
How do I charge the Mares EOS Strobe?
The EOS Strobe uses USB charging and includes a charging-status indicator. Published charging times are approximately six hours with a 5 V/1 A supply or twelve hours with a 500 mA USB connection.
How do I attach the EOS Strobe to my BCD?
Use a secure, suitable attachment point and compatible retention hardware. Keep the light accessible and positioned so it cannot interfere with hoses, controls, or safe movement underwater.
What is the maximum depth rating of the Mares EOS Strobe?
Mares advertises 120 m, while detailed technical listings also report 100 m. Confirm the approved rating of your exact product revision before using it beyond 100 m.
What should I do if the Mares EOS Strobe does not turn on?
Check the charging status, rotary switch position, and accessible external contacts or seals according to the Mares manual. If the light still fails, stop using it underwater and contact Bluewater Photo or Mares for support.
How should I maintain the EOS Strobe after saltwater diving?
Rinse the exterior with fresh water after diving, dry it before storage, and inspect the seals following manufacturer instructions. Never open a charging compartment or battery housing while wet.
