Choosing modern and over-dimensional components in combination
with tested micro-processor electronics results in one of the most powerful
and fastest recycling underwater strobes in the world.
The core of the Hartenberger strobes is the powerful and robust transformer.
This allows a power rating of 625 watt/seconds and a recycle time at full
power setting of 0,8 seconds !! (see technical specifications). The recycle
time using lower power settings allows more than 10 frames per second
(vital for fast motor drive use).
After recharging the condensers, the transformer switches off automatically.
This reduces cell use and also avoids the prolonged radiation caused by
the charging which disturbs some underwater life, causing them to flee.

The strobe ready signal appears on the switch panel of the
strobe and in the viewfinder of the camera and easily visible. At the same
time, a short acoustical signal (beep) can be heard.
The camera shutter speed is automatically set according to the synchronisation.
A special technical feature of our strobes is the extremely
short flash duration hereditary in ring formed strobe tubes.
This is necessary because some Nikon cameras (i.e. F5, F100, F90...) require
the entire light for a correctly exposed picture within 1/500th of a second.
Should the strobe require longer than this to achieve the correct exposure,
then the camera will not send out the TTL cut off signal to the strobe!!!
In this case, the remaining energy is released as light and results in an
uncontrolled, overexposed picture. |
