Frequently Asked Questions
About Siros S
What is the difference between a monolight and a power pack?
A monolight combines power supply and lamp unit in one housing. There is no need for a lamp cable, making the device very handy and convenient. A battery powered monolight allows you to work completely wireless. In order to keep size and weight to a minimum, monolights are limited when it comes to flash power. Each monolight features its own controls and works independently of other monolights. The whole system is not down in case of a technical issue.
A power pack usually stands on the ground, therefore size and weight are not as critical as compared to monolights. Therefore, they offer substantially more flash power. Several lamp heads are connected to and controlled by one power pack. In case of a failure the whole system may be temporarily down. The (separate) lamp heads are much smaller and lighter than monolights.
Does Siros S feature the broncolor HS function?
Only Siros 800 S does feature the HS function (flash power level 4 to 10 only) , Siros 400 S is not supported.
Please note: both battery devices Siros 400 L and Siros 800 L feature the HS function.
Can the broncolor HS function be retrofitted?
No, as there are not only software but hardware modifications as well, this function can not be retrofitted.
Which radio remote controls can broncolor Siros S monolights be controlled with?
- broncolor RFS 2.1 system:
- RFS 2.1 Transceiver (Transmitter kit) | item number 36.133.00
- broncolor RFS 2.2 system:
- RFS 2.2 C Transmitter (Canon) | item number 36.160.00
- RFS 2.2 F Transmitter (Fujifilm) | item number 36.163.00
- RFS 2.2 N Transmitter (Nikon) | item number 36.161.00
- RFS 2.2 S Transmitter (Sony) | item number 36.162.00
Is colour consistency maintained when using HS?
Activating the broncolor HS function has a small influence on colour temperature.
However, other light sources such as daylight or ambient light usually have a stronger impact on colour temperature.
Hence, the broncolor HS function’s influence on colour temperature is alleviated in sunny conditions.
HS is meant to be used in a bright outdoor environment.
How does HS compare to short flash duration?
Without HS, the minimal flash duration cannot be shorter than the fastest shutter speed of the camera (X-sync).
The broncolor HS function provides a way to circumvent the restriction imposed by the X-Sync time:
1) The flash fires before even one pixel of the image sensor has been uncovered
2) The first shutter curtain starts to open.
3) The second shutter curtain starts to close (think of it as a scanning procedure).
4) The flash continues to burn (like a continuous light) and only stops when the scanning procedure is complete. For this reason we need the longest possible flash duration. The result is a great feature; now you can use a large aperture to provide an out-of-focus background, or simply freeze super-fast motions.
What kind of modelling light does the Siros S have?
Halogen max. 300W/120V

Siros S Key Features
-
Abundant power
With up to 800 joules of power and carefully calculated reflectors, you can illuminate the largest sets as well as achieve outstanding results when photographing against the sun.
-
Impressive speed
Freeze the moment with its extreme short flash duration of up to 1/8500 s (t 0.1) - shorter than the fastest shutter speed of your camera. With the impressive recycling time on the Siros S, you can trigger your next shot in 0.02 seconds.
-
Easy to use
The single rotary controller makes it extremely easy to operate the Siros S. It enables you to change the power outlet precisely in full or 1/10 f-stops increments over the entire power range of 9 f-stops and access all advanced settings in the menu.
-
bronControl
Alternatively, you can remotely control your Siros S with the advanced and intuitive bronControl app. It gives you access to many more creative functions such as sequences, delays, alternate, freemask and more.
-
Home around the world
Siros S automatically adapts to the main (AC-line) voltage 100-120 V and 200-240 V.
The quality of the light is fantastic
Built like a tank, the quality of the light is fantastic, they are always consistent, and having something less to worry about during a shoot, I suppose we are all going to agree, is always so much appreciated.
Then, during the shoot, when I needed to change between backgrounds (white and grey), using the WiFi app on the Siros made it super-quick and easy to just turn off my background lights and I was ready to shoot right away.
