Broncolor Siros 400L

Siros L is battery-powered

A single fully-charged lithium-ion battery stores enough energy for a Siros 400 L to flash more than 440 times – and it does that at maximum power! A miracle? No, quality!

Siros L is fast

In only 0.03 seconds your Siros L is ready again. The flash duration can last less than 1/9000 s (t 0.1) or 1/19’000 s (t 0.5). Truly miraculous times.

Siros L is simple

Very simple operation using the single rotary controller. Alternatively you can use the advanced, intuitive app. Either way using Siros L is fun.

Siros L is powerful

The high light output, up to 400 J, leaves no photographer standing in the dark – it can even challenge sunshine.

Siros L is LED

With its low power consumption, the 25 Watt LED module provides bright modelling light at a colour temperature of 3200 K.  The light characteristics is absolutely comparable with the modelling light from a mains-operated Siros S.

Siros is Swiss

Do you appreciate quality? In Siros L you have Swiss precision and quality – inside and out. Be inspired!

Siros L is family

Proven meets innovation! The battery-powered Siros L, the Siros studio lights and Siros S are all available in both 400 and 800 Joule versions. Equipped with the broncolor bayonet fitting, they are part of the best light system in the world.

Endless battery power

For over 50 years broncolor has been synonymous with innovation and an uncompromising commitment to the highest light quality. And again with Siros L there are no trade-offs.

It is a real broncolor.

With the latest lithium-ion technology, a single battery, in spite of its very compact size and low weight, can charge a Siros 400 L up to full power 440 times!
Reduce the output, for example by just 2 f-stops, and you can have over 1700 flashes!
The results will convince you. The battery can be used over a very wide range of temperatures – from −10° C to +60° C degrees Celsius. This gives you a free range of locations – at the North Pole or in the desert, Siros L is your reliable companion. When discharged, this high quality battery takes only 70 minutes to fully charge again.
In Siros L too, the ECTC technology you know from our high-end Scoro and Move power packs controls the flash curve, enables flash durations from 1/19’000 s (t 0.5)In addition, it guarantees constant colour temperature over the entire control range.

Operation: as simple as possible for maximum convenience

All the basic functions of Siros L can be operated using the free “bronControl” app.
As soon as Siros L is logged in to the Wi-Fi network, you can control several devices using a smartphone or tablet with each clearly identified by differen tcoloured LEDs. In this way equipment that is difficult to access or far away can be conveniently and easily set and controlled.
Independently of the existing Wi-Fi environment, Siros L can set up its own network. One more advantage: the app controls the functions of up to 6 units with absolute clarity and full individual control. But even without the app, Siros L is still simple and intuitive to operate. With the single rotary controller, the “Twist Function” lets you set the output very quickly over several f-stops or very precisely in 1/10 f-stop steps.
By pressing on the same knob you have access to the menu and to all the additional functions. There’s no simpler way.

Perfect light without restrictions

The control range extends over a full 9 f-stops.
At high output it can even “outflash” bright daylight. And low settings enable photography even with wide-open apertures.  You can be certain that Siros L will never restrict your choice of aperture – it is every photographer’s ideal companion.
Many light shapers, such as Softboxes, open reflectors and above all Paras are parabola-shaped and only guarantee optimum light yield and quality when the light source is as close as possible to the internal focal point of the reflector.
As a consequently, for Siros L we decided in favour of an external flash tube, resulting in perfect light without compromises.
Broncolor has the most comprehensive light-shaper accessory system and, with its compatible design, Siros L is completely integrated into it.
In addition, two new reflectors have been developed especially for Siros: An umbrella reflector, which is equipped with a cover that also serves as transport protection, and a size-optimised standard reflector, the L40, which has a snap-in system for honeycomb grids or barn doors with filter holder.
