broncolor Monolights

Broncolor Siros 400 S WiFi / RFS 2, Monolight. Raise your ambitions and foster your creativity with the uncompromising power as well as the vast amount of functions of the Siros S. Enough power to face any challenge, control range of 9 f-stops, extremely fast flash duration, while maintaining absolute colour constancy – the Siros S has it all in one compact and sturdy housing. In addition, our frontrunner monolight is equipped with the Broncolor bayonet, which opens up a world of high-quality accessories for maximum creativity and efficiency.

Abundant power

With up to 400 joules of power and carefully calculated reflectors, you can illuminate the largest sets as well as achieve outstanding results when photographing against the sun.

Impressive speed

Freeze the moment with its extreme short flash duration of up to 1/5500 s (t 0.1) - shorter than the fastest shutter speed of your camera. With the impressive recycling time on the Siros S, you can trigger your next shot in 0.02 seconds.

Easy to use

The single rotary controller makes it extremely easy to operate the Siros S. It enables you to change the power outlet precisely in full or 1/10 f-stops increments over the entire power range of 9 f-stops and access all advanced settings in the menu.

bronControl app

Alternatively, you can remotely control your Siros S with the advanced and intuitive bronControl app. It gives you access to many more creative functions such as sequences, delays, alternate, freemask and more.

The quality of the light is fantastic

"Built like a tank, the quality of the light is fantastic, they are always consistent, and having something less to worry about during a shoot, I suppose we are all going to agree, is always so much appreciated. Then, during the shoot, when I needed to change between backgrounds (white and grey), using the WiFi app on the Siros made it super-quick and easy to just turn off my background lights and I was ready to shoot right away."

Broncolor Siros L 400 WiFi / RFS2, battery-powered monolight. A 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.

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 1/9000 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 400 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.

Bron Elektronik AG, founded in 1958, with its well-known broncolor brand, has developed over the past half-century into a global player in the international market for professional lighting systems. broncolor aims to produce State of the Art products, housing in a corporate and modern design including broncolor's technological innovations and guaranteeing an unbeatable quality standard. This is also what you expect from broncolor in your daily work in the studio or on location.
broncolor aims to meet your needs and continuously surprise you with innovations - this is what ignites their passion.

Stelos is broncolor’s top model among battery-powered monolights – built for professional photographers who refuse to compromise. With 800 joules of flash energy, battery operation with simultaneous charging while in use, and the legendary broncolor light quality, you get full freedom both in the studio and on location. The unit is compact and intuitive: two buttons, a combined rotary/push control and a clear menu save valuable time on set. The bright LCD screen can be customised to your needs – from minimalist to a full overview.

• 800 J flash energy
• Battery operation with charging while in use
• Over 300 flashes at full power
• Variable flash colour temperature
• HSS (High Speed Sync)
• LED modelling light 2700–6500 K
• Battery with V-mount universal interface

V-Mount battery interface

Thanks to the universal V-mount interface, the Stelos works with a wide range of batteries from broncolor and third-party manufacturers. Charging is done easily via USB-C, either with a standard laptop charger or the supplied 140 W charger.

Adjustable colour temperature

A unique feature for monolights is the variable flash colour temperature — previously exclusive to broncolor’s high-end power packs. High Speed Sync (HSS) is of course included. The LED modelling light is powerful and adjustable between 2700–6500 K.

Large accessory range

The solid bayonet mount gives you access to broncolor’s extensive range of light shapers — even the largest can be used safely. Full compatibility with RFS 2 and 3 transmitters, the bronControl app via built-in WiFi and bronAPI for integration into custom applications make the Stelos a future-proof solution.

In larger setups identification is easy thanks to the multi-coloured Cognition Lights. The Stelos can also be tilted 90° up and down on a stand, all parameters can be controlled directly on the unit, and the size has been significantly reduced — broncolor has listened to photographers worldwide and given them creative freedom.
