Product Information
The Sea & Sea YS-D3 MKII LIGHTNING is an underwater strobe rated to 100m / 330ft with a Guide Number of 33 (28 with the diffuser attached). This listing does not include the Fiber-Optic Cable.
Who it is for
It suits underwater photographers shooting through a Sea&Sea or third-party optical TTL converter, since the YS-D3 MKII LIGHTNING carries a newly designed circuit that improves TTL accuracy and converter compatibility over the original YS-D3 LIGHTNING, while keeping the same product number (03123) as a running change update.

- 140 flashes on alkaline batteries, 220 flashes on Ni-MH batteries, with a full recycle time of 3.5 seconds (alkaline) or 1.7 seconds (Ni-MH)
- Color temperature 5800K without the diffuser, 5500K with it
- Depth rated to 100m / 330ft

Frequently Asked Questions
Does this YS-D3 MKII LIGHTNING come with the Fiber-Optic Cable?
No, this DiveCatalog listing does not include the Fiber-Optic Cable. The strobe can be triggered through a 5-pin Sync cord/N or a Fiber-Optic Cable. The box holds the strobe unit, Ball Mount Strobe Adaptor, Diffuser, silicone grease and DiveCatalog's Coil Lanyard, so source a Fiber-Optic Cable separately.
What batteries does the YS-D3 MKII LIGHTNING use and how many flashes do they last?
It runs on 4x AA batteries, 6V with alkaline or 4.8V with Ni-MH. Alkaline batteries deliver about 140 flashes with a 3.5 second full recycle time, while Ni-MH batteries deliver about 220 flashes with a faster 1.7 second recycle time.
How is the YS-D3 MKII LIGHTNING different from the original YS-D3 LIGHTNING?
It is a running change update, so the product number (03123) stayed the same. The MKII version uses a newly designed circuit and aspherical optical toroidal lens that improve TTL light intensity accuracy and compatibility with Sea&Sea and third-party optical TTL converters, while keeping the same Guide Number, beam angle, and depth rating as the original.
