Stelos is broncolor’s latest flagship portable monolight, delivering 800 joules of flash energy and legendary light quality.
It runs on battery power with simultaneous charging via USB-C, using a standard or included 140W charger. The intuitive interface features just two buttons, a rotary controller, and a customisable LCD display. Stelos supports all broncolor RFS 2/3 transmitters, the bronControl app (WiFi built-in), and bronAPI. A solid bayonet mount handles even the largest light shapers. Features include adjustable flash colour temperature, powerful LED modeling light (colour adjustable), HSS, and user-driven upgrades like 90° tilt and compact size. Made in Switzerland for lasting reliability.
Compact 800 joules power
Stelos delivers an impressive 800 joules of flash energy in a remarkably compact and lightweight form. Designed for mobility and speed, it’s the perfect companion for fast-paced shoots—on location or in the studio. Despite its size, Stelos offers full performance without compromise.
Universal V-mount battery
Thanks to its V-Mount interface, Stelos supports a range of batteries from broncolor and third-party providers. Power your shoots flexibly, and charge using the included 140 W adapter or any USB-C charger—even while in use.
Renowned broncolor light quality
Stelos continues the broncolor legacy of exceptional light quality with precise colour consistency, adjustable flash colour temperature, and powerful, tunable LED modeling light. Whether you're shooting stills or video, expect professional results with every flash.
800 J of flash energy
Li-Ion battery (charge while in use)
Universal V-Mount interface (broncolor Stelos battery or suitable third-party batteries)
More than 300 full power flashes with a single battery charge
Legendary broncolor light quality (output consistency and colour temperature stability)
Flash colour temperature is adjustable
Powerful LED modelling light (2700 to 6500 K)
High-Speed-Sync (HSS)
Large display with excellent readability and a modern, intuitive user interface (currently 11 languages supported)
Fully compatible with RFS 2.1., RFS 2.2 and RFS 3 radio triggers
bronControl App or bronAPI available
Can be tilted up or down by 90 degrees on the stand
Up to 800 joules and carefully calculated reflectors never leave you in the dark. Siros L illuminates even your largest sets or dominates the sun. High-speed synchronisation ("HS") is integrated as well.
A single charge of the compact and lightweight battery stores power for up to 440 flashes. Full power flashes!
In only 0.03 s, the Siros L can be ready for the next flash. The flash duration can be as short as 1/9000 s (t 0.1) - shorter than the fastest shutter speed of your camera!
The LED modelling light consumes 25 W only but it is bright enough to build your set and focus properly. The colour temperature of 3000 K matches perfectly with the modelling light of Siros S.
Very simple operation using the single rotary controller. Alternatively, Siros L can be controlled via the advanced, intuitive bronControl app.
