Swiss-built Broncolor Siros heads have been developed for high-end studio applications, where exact colour replication, speed and operability are primary considerations. Compact, reliable and precise, Siros produces an extremely consistent light in terms of temperature, brightness and duration. A joy to handle and easy to operate via a simple, illuminated dial or phone/tablet app, Siros is certainly one of the finest studio lighting heads available.

Key Features:

Siros is fast
With flash durations from 1/8000s (t0.1) or 1/13000s (t0.5) and recycling times from 0.02s, you can capture every moment perfectly. 'Fast' mode prioritises speed - capturing motion brilliantly.

Siros is simple
Operated by the single, illuminated rotary controller or the advanced Broncontrol app. Both are intuitive.

Siros is powerful
High light output in a robust aluminium housing leaves no photographer standing in the dark.

Siros is Swiss
Swiss precision and quality - designed and manufactured in Switzerland.

Siros is family
Available in basic, standard and S versions, and in 400J and 800J variants. Optional radio synchronisation via RFS2.1 transmitter.

Demonstration video

Broncolor’s new compact device combines unbeatable flash- and super-fast charging times with reliable and intuitive handling. At 400 or 800 joules, Siros is available in two output versions and also as either a basic- or S- high-end model.
The flash time curve in the new Siros is controlled by Broncolor’s widely known ECTC technology, which also guarantees flash times of up to 1/13,000 s (t 0.5) and constant colours. Charging times of 0.02 up to 0.65 s at 400 joules as well as an enormous control range – up to 9 apertures and reducible to only 2 joules – round off the impressive performance of the S high-end model.
Furthermore Siros is fully compatible with the extensive accessory range of light shapers that Broncolor is so well known for and which offer limitless creative possibilities. Two of these light shapers have been especially developed for Siros: an umbrella reflector; which - combined with a lid - can also be used for protection during transport and an L40 reflector, optimised in size and - through a snap-in system - easily extendable with a honeycomb grid. Handling and menu navigation are both easy and intuitive with Siros and are regulated through a single control dial, which allows for aperture adjustments in 1/10 steps or, by using the new ‘twist’ function, in full apertures.

Brand-new app ‘bronControl’ for all-round control
Also new with Siros is the ‘bronControl’ app, which allows remote control of all functions and is compatible with iOS tablets and phones, with full Android support shortly available (as of Feb/15). As soon as Siros has established a Wi-Fi network, different devices in the studio or outdoors are recognised via multi-coloured LEDs and can be controlled via a smartphone or tablet.
