Broncolor 400 S Overview

Providing a 400Ws output in a compact design, the Siros 400 S WiFi/RFS 2.1 Monolight from Broncolor is a reliable studio flash unit with Wi-Fi connectivity and a built-in RFS 2.1 receiver for wireless control and triggering. It has a 9-stop power range which is adjustable in 1/10 or full stop increments for great control over light output. The Siros S is also quite fast with a flash duration from 1/8000 - 1/1000second and a recycle time of 0.02 - 1.4 seconds depending on power settings. Additionally, the monolight has a halogen modeling light.

Built into the Siros S is a specialized Speed Mode that speeds up the charging time and flash duration to provide a fast sequence of exposures, up to 50 per second at the fastest setting. Also, the unit has a USB connection for software updates and is fan cooled for temperature control. An integrated reflector and mount are included for adding modifiers to the light.

When the Siros is connected to a Wi-Fi network, each light can be identified by a different-color LED and can be easily controlled using the bronControl app for smartphones and tablets
With the integrated Broncolor RFS 2.1 receiver, users can use the RFS 2.1 transmitter for remote control from the camera
Cut-off technology uses a microprocessor to calculate the flash duration to an output, enabling sequences with up to 50 flashes per second
Enhanced Color Temperature Control technology adapts flash voltage and duration in order to achieve a constant color temperature over the entire variation range
Individual power distribution means the unit has controllers for each lamp in order to have greater control over the flash power range
Speed mode reduces flash duration and charging time while reducing the maximum power in order to achieve a series of rapid exposures without overheating
Single rotary control for flash power output setting, a slight turn provides 1/10 stops while a "Twist" function allows for whole stops
Internal discharge when power is reduced
Grip features double-wall plastic with a special coating for durability and comfort
Aluminum stand adapter can be used with the handle to function as a built-in floor stand
Standard sync port and built-in photocell are available for more elaborate triggering setups
Black aluminum body construction
Designed and developed in Switzerland

Are these heads battery powered and HSS capable?
Asked by: Gerardo G.
The Siros 400S is powered by a wall outlet and is not HS compatible. BUT the battery powered version - Siros 400L (B&H # BRS400LWFR2B MFR # B-31.710.07) is completely battery powered and HS compatible for Canon, Nikon, and Sony.
