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.
Providing a 800Ws output in a compact design, the Siros 800 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 - 1/500second and a recycle time of 0.07 - 1.35 seconds depending on power settings. Additionally, the monolight has a halogen modeling 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
