Broncolor Siros 800 L WiFi / RFS 2.1 - 25% OFF WITH TRADE-IN

OFFER ENDS 31/05/2026 - CONTACT US FOR DETAILS.

The Siros L is Broncolor’s battery-powered monolight, which provides ambitious professional photographers with the opportunity to enjoy the perfect lighting, be this in a mobile form in the studio, or for external shots – offering up to 440 flashes at full power per battery charge, colour constancy and very fast flash durations. Easy to control with the bronControl app. Available in 400 and 800 joules.

All Siros L units with the latest software update are “HS” compatible. “HS” lets you use flash in combination with shortest shutter speed settings on your camera. For example, with ambient light, even with the aperture wide open (selective focus), the image can be underexposed correctly with up to 1/8000 s and Siros L still lets you set dominant and creative light effects.

All you need for this is the RFS 2.2 trigger, which is available for Nikon, Canon, Fuji and Sony cameras. 

Abundant power

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. 

Battery endurance

A single charge of the compact and lightweight battery stores power for up to 440 flashes. Full power flashes! 

Impressive speed

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! 

LED modelling light

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. 

Easy to use

Very simple operation using the single rotary controller. Alternatively, Siros L can be controlled via the advanced, intuitive bronControl app.
