Product Information
The Sea & Sea YS-03 SOLIS Lighting System is an all-in-one underwater strobe package that bundles the YS-03 SOLIS strobe with a Flexible Grip 280X & Single Tray X arm and tray set and an Optical Fiber Cable II with M/2 connectors, giving divers a ready-to-mount slave TTL strobe kit for a compact camera and housing combo. It has a guide number of 20 (ISO 100, land value) and a depth rating of 75 meters.
Who it is for
This system is built for divers running a compact camera and housing combination whose built-in flash offers a pre-flash TTL exposure function. Because the package already includes the arm, tray, and fiber-optic sync cable along with the strobe, it suits shooters who want the core lighting components bundled together rather than sourced piece by piece.
Key details
- Guide number 20 (ISO 100, land value); beam angle 100 by 100 degrees, or 110 by 110 degrees with the diffuser
- Color temperature 5600K, or 5250K with the diffuser
- Powered by 4x AA batteries: alkaline (6V) rated for 230 flashes, or Ni-MH (4.8V) rated for 300 flashes
- Recycle time 2.5 seconds on alkaline or 1.9 seconds on Ni-MH
- Depth rating of 75 meters
- Body dimensions 68mm (W) x 108mm (H) x 129mm (D); weight 430g (body only, batteries excluded), with an underwater weight of approximately +10g with batteries installed
- Single dial-style power switch with only an OFF to TTL adjustment and an auto power-off function
Compatibility and sizing
The YS-03 SOLIS strobe is designed to work with any camera that has a pre-flash and TTL flash exposure function. It requires an optical fiber cable to sync with the camera's built-in flash, and Sea & Sea's own optical fiber cables are recommended for this connection; this system includes the Optical Fiber Cable II with M/2 connectors for that purpose.

Frequently Asked Questions
Does the Sea & Sea YS-03 SOLIS support TTL exposure?
Yes. The YS-03 SOLIS operates as a slave TTL strobe, syncing optically to the camera's built-in flash to achieve TTL exposure. The power switch only offers an OFF to TTL adjustment, and it requires an optical fiber cable, included in this system, to communicate with a camera that has a pre-flash TTL function.
What batteries does the YS-03 SOLIS use and how many flashes can I expect?
The strobe runs on 4x AA batteries, either alkaline (6V) or Ni-MH (4.8V). Alkaline batteries are rated for about 230 flashes with a 2.5 second recycle time, while Ni-MH batteries are rated for about 300 flashes with a faster 1.9 second recycle time.
What is the difference between the YS-03 SOLIS Lighting System and the YS-03 SOLIS strobe alone?
The YS-03 SOLIS Lighting System (part number 03126) bundles the YS-03 SOLIS strobe with a Flexible Grip 280X & Single Tray X arm and tray set and an Optical Fiber Cable II with M/2 connectors. The strobe alone (part number 03125) does not include the arm, tray, or cable.
What is the depth rating of the Sea & Sea YS-03 SOLIS strobe?
The YS-03 SOLIS strobe included in this lighting system is depth rated to 75 meters. The strobe body weighs 430 grams without batteries, with an underwater weight of approximately +10 grams once batteries are installed.
