Sea & Sea YS-D3 Lightning - Underwater TTL Strobe

Controlled lighting, high precision circuitry
enabling the D-3 to fire at any moment.
The YS-D3 LIGHTNING is equipped with a
maximum Guide Number of GN33 and maximum
beam angle of 100°. The two-stage recycle time
function provides priority shutter availability.

High-Performance Strobe

The latest D3 circuitry and light-emitting strobe produces
a powerful guide number of 33. A newly developed high
precision aspherical optical troidal lens has been fitted
over the two flash tubes to disperse an even light from the
center to the edge. The strobe’s beam angle will increase
to 100° or 120° by attaching standard diffuser accessories.
When the optional Dome diffuser is attached, beam angle
will increase to 140°.

Superior Consecutive Firing Capability
to Capture those Critical Moments

The YS-D3 utilizes larger capacity condensers compared
with those used on competing strobes. In addition, the D3
is also equipped with a newly designed charging circuit.
As a result, the YS-D3 will fire at GN16 continuously
without any interval time. Even when the strobe is fired at
GN22, the strobe will fire again within a mere 0.6 seconds.
When the YS-D3 is fired at Guide Number over 22, a twostage
ready-to-fire signals will be issued. For instance,
after the strobe fires at full power of GN33, the strobe will
inform you both visually and audibly when the condenser
is charged to fire at GN22. Then, when the condenser is
charged enough to fire at GN33, another different signal
will be issued.
This design allows you to release more shutters in scenes
where you want to shoot as many pictures as possible,
maximizing shooting intervals between scenes.

Target Light with Increased Power

Incorporating a uniquely designed aluminum heat diffuser,
the target light is now powerful enough to be used as a
dive light.
