You can sense the performance and robustness of Siros L from afar. The elegant, black aluminum body of Siros L makes a powerful statement, but its simplicity and ease of use are equally impressive. Sirs L was entirely designed and developed in Switzerland. Production and quality control also remain at the headquarters of Bron Electronic AG and so guarantee the familiar high quality of every bronchiolar device. Innovative technologies from the prize-winning Scoro and Move power packs have even adapted to the Siros L.
Cut-off technology
Flash duration and light output are the two decisive factors in light control.
A microprocessor in Siros L will calculate the shortest flash duration for a given energy setting. That is convenience!
Constant color temperature – ECTC
The second generation of our patented ECTC (Enhanced Color Temperature Control) technology, which adapts flash voltage and flash duration to each other, ensures a constant color temperature over the entire output range. Reliability at the highest level.
Individual power distribution
With Siros L you have a free choice of 9 f-stops to set the flash output you need, all the way to 2 Joules. Photography with maximum freedom.
Speed Mode
In Speed Mode fast charging and short flash times have absolute priority. In this case the calculation of constant color temperature (ECTC) is suppressed.
Lithium-ion battery
The latest lithium-ion technology in the batteries enables charging times never achieved before, and supplies energy for over 440 complete charges to full power - and all this from a weight of only 0.6kg. It makes photography pure pleasure
