For over 50 years broncolor has refused to compromise on the quality of light. In this sense, Siros is a true broncolor product.


The Siros S includes the ECTC technology you know from our high-end Scoro and Move power packs. ECTC controls the flash curve and guarantees flash durations from 1/19’000s (t0.5) and constant colour at all times.


The enormous control range goes up to 9 f-stops, resulting in output as low as 2 joules which gives the photographer an unrestricted choice of aperture. And the lightning-quick charging time, 0.02 to 0.9 s at 400 joules, means you never have to wait.


broncolor offers the world’s most comprehensive range of light modifiers. Siros is fully integrated into this system of unlimited creative possibilities.



Innovative technologies from the prize-winning Scoro and Move power packs have been adapted to the Siros S monolight.


Cut-off technology
Flash duration and light output are the two decisive factors in light control. A microprocessor in the Siros will calculate the shortest flash duration for a given output for you. This enables rapid flash sequences with up to 50 flashes per second.


Constant colour temperature – ECTC
The second generation of our patented ECTC (Enhanced Colour Temperature Control) technology, which adapts flash voltage and flash duration to each other, achieves a constant colour temperature over the entire output range.


Enormous control range
With Siros S you have a choice of 9 f-stops to set the flash output you need, from the top power level all the way down to 2 joules.


Speed Mode
When the instant counts, it is time for Speed! In Speed Mode you can set the fastest flash duration as the exclusive priority. When using Speed Mode, constant colour temperature functions (ECTC) are suppressed.



Operate your Siros with an app!
All the basic functions of Siros can be operated using the new bronControl app. As soon as Siros is associated with a WiFi network, each device in a studio is clearly identified by different-coloured LEDs and can be controlled using a smartphone or tablet.


The photographer can make all necessary settings and adjustments at the camera using their chosen device – conveniently and simply. This saves time and lets the photographer concentrate on his or her work.


App is available on App Store and Google Play Store.
