The Z-240 and D-2000 strobe (*1) has two flash tubes in "T" configuration and unique reflecting mirrors (*2) to provide wide 100° circular beam angle without diffuser panel.
T-shape Twin Flash
The T-shape Twin Flash having two flash tubes in T-shape configuration generates 100 degree circular beam all around enabling free and flexible strobe position without considering camera's orientation. Together with INON arm system enabling free strobe position, the T-shape Twin Flash benefits you with flexible and creative lighting even shooting with a wide lens. Also the wide beam angle is delivered without a diffuser where maximum strobe power is usable even for wide imaging.
Conventional strobe with single flash tube
A strobe with single flash tube has rectangular reflecting mirror emitting oval beam creating blind corners if the strobe is not properly aligned with a camera. So strobe position has to be rather limited to evenly cover all image area even using an arm system allowing free strobe position. Using a diffuser panel makes the beam more like circular pattern but this is trade off against flash power.
T-shape Twin Flash creating soft shadow
Single T-shape Twin Flash strobe
Single flash tube type strobe
Another advantageous feature of the T-shape Twin Flash is to soften a shadow. Larger light emitting area of two flash tubes, together with T-shape configuration design, creates less and soft shadow. Attaching a diffuser panel prevents washout.
(*1) T-shape Twin Flash is also used for other INON strobe; Z-330, D-200, D-2000S, D-2000W/Wn, Z-240, Z-220 series and D-180 series
(*2) T-shape Twin Flash is patented in the U.S. (No.6,518,714) and in Japan (4458602).
