The new SESA&SEAS YS-D3 LIGHTNING is equipped with a maximum Guide Number of GN33, maximum beam angle of 120°, and high precision circuitry enabling the new SEA&SEA YS-D3 to fire at any moment. The two-stage recycle time function provides priority shutter availability.

Product Features:
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 150°. (Aspherical troidal lens is located in front of the flash tube.)
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 two-stage 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.
