Frequently Asked Questions
What is the benefit of the broncolor HS technology included with the Siros 400 L flash heads?
The broncolor HS technology allows the Siros 400 L flash heads to sync with camera shutter speeds up to 1/8000s, enabling photographers to overpower ambient light and achieve wide aperture effects even in bright conditions.
How do the two Lithium-Ion batteries contribute to the portability of the Broncolor Siros 400 L kit for outdoor use?
The two included Lithium-Ion batteries provide untethered power to the Siros 400 L flash heads, allowing photographers to operate the lighting system effectively in outdoor locations where mains power is unavailable, significantly enhancing portability.
What is the primary use case for the included 85 cm silver/black umbrella and the 60x60 cm softbox?
The 85 cm silver/black umbrella is ideal for producing a broad, soft, and slightly specular light, while the 60x60 cm softbox with its adapter ring provides more controlled and diffused directional lighting for portraits or product photography.
Is the outdoor trolley backpack durable enough to protect the equipment during transport to various locations?
The outdoor trolley backpack is designed to provide protected transport for the entire Broncolor Siros kit, offering convenience and security for photographers moving between different shooting locations.
Can the Siros 400 L flash heads be controlled remotely, or do they primarily rely on the sync cable?
While the kit includes a 5m sync cable, Broncolor Siros flash heads typically feature built-in wireless control capabilities, allowing for remote power adjustment and triggering when used with a compatible transmitter.
