Stelos
Make the world your studio
For over 65 years, broncolor has delivered lighting solutions trusted by the world’s most demanding creators. With this next generation of monolight, we’re setting a new standard for on-location photography. Swiss innovation and precision – at its finest.
 | Impressive powerWith 800 joules of flash energy, Stelos delivers remarkable power despite its compact design. Its control range from 1 to 11 equals a dynamic range of ten f-stops – ideal for everything from the most delicate accents to powerful key lights. |  | Colour temperatureA first for a monolight: Stelos offers variable flash colour temperature – a feature previously reserved for high-end generator systems. This gives you creative control over the character of your light right from the source. |
 | V-Mount batteryThanks to the universal V-Mount interface, you can use batteries from broncolor as well as from third-party manufacturers. Charging is possible either with the included 140-watt charger or with any USB-C charger. |  | Intuitive interfaceStelos features a modern, user-friendly interface: just two buttons, a rotary push dial, and a clear, customizable menu help you work faster and stay focused. The high-contrast LCD screen can be set to a minimalist view or display all key parameters at once. |
 | Engineered to lastBuilt in Switzerland with premium materials and components, Stelos is made to endure. Whether in the studio or out in the elements, it’s your reliable companion. Long-term parts availability and repairability are part of the broncolor promise. |  | Tilt functionalityOur development team listened closely to user feedback: Stelos can now be tilted 90° up and down when mounted on a stand – a simple but powerful improvement that gives you even more flexibility for creative setups. |
Stelos is the latest flagship model among broncolor’s mobile monolights.
With 800 joules of flash energy, legendary broncolor light quality, and battery operation that allows charging while in use, it lets you make the world your studio.
Stelos combines maximum performance with outstanding portability. Its fast flash durations and precise colour stability open up new creative possibilities.
At the same time, it’s rugged enough for demanding on-set use and light enough to take with you anywhere.
Thanks to the broncolor bayonet mount, Stelos is compatible with the full range of light shapers and accessories. From small reflectors to large softboxes – all the familiar tools can be used without an adapter.
High-capacity lithium battery with quick-swap function: The V-mount battery is easy to remove and can be transported separately, making it more convenient to pack for on-location shoots. Its slim design allows multiple batteries to be stored side by side to save space. Five LED bars on the battery indicate the charge level or remaining capacity. One battery provides over 300 flashes at full power.
 | Charging and useThe battery can be used at all power levels while charging simultaneously. This makes Stelos both a truly mobile unit and a fully studio-capable compact device. Despite its portability, it delivers substantial power wherever you need it. |  | broncolor light qualitybroncolor light quality is defined by consistent output across the entire control range. Thanks to its always-rectangular flash curve, there is no drop in power at the end of the flash. This ensures both light intensity and colour temperature remain stable at all times. |
 | High-speed syncWorking with the shortest camera shutter speeds requires long light pulses. For this, Stelos reduces the intensity while maintaining a perfectly rectangular flash curve. As a result, light intensity stays consistent throughout the flash duration, ensuring even illumination across the entire sensor – even in HSS mode. |  | Light distributionAs with all high-end broncolor devices, the flash tube protrudes slightly. This guarantees perfectly even illumination inside light shapers such as parabolic reflectors – a technical detail with a big impact on light quality and brilliance. |
 | Built-In bronControlStelos features an integrated bronControl radio system for seamless operation via the bronControl app. This allows multiple units to be synchronised and centrally controlled. Firmware updates can also be carried out conveniently via the app. |  | ConnectivityIt is fully compatible with broncolor RFS 2 and 3 transmitters, the bronControl App via its integrated WiFi module, and even your custom applications through the bronAPI. All core functions are available directly on the device, no app required. |
 |  |  |
| Like all premium broncolor units, Stelos features a protruding flash tube. This design ensures that the light fills every corner of a modifier evenly, from the deepest parabolic reflector to the broadest softbox. The result is a beautifully uniform spread with exceptional clarity and tonal richness. | Thanks to the universal V-Mount interface, you can use batteries from broncolor or third-party manufacturers. Charging is equally flexible: either via the included 140-watt USB-C charger or a standard laptop charger. The secure, quick-lock mechanism of the V-Mount ensures fast battery changes and a reliable connection, even during demanding shoots. | The high-contrast display remains easily readable even in bright ambient light. All key settings are intuitively accessible and can be adjusted directly on the unit or conveniently via a trigger. Its clear menu structure supports both beginners and professionals in navigating quickly and efficiently. |

Swinging between light and dark
When the team from Switzerland asked me to test the new broncolor Stelos, I knew I wanted to take it straight to the streets of Berlin. I teamed up with the charismatic jazz musician David Hermlin, and together we set out to see what this light could really do.
Right away, I loved how compact it was. The side-mounted battery clicks off in a second, making it easy to travel light between locations. Indoors, I could plug it in while shooting, and it would quietly recharge itself — so when we stepped outside again, I had a fresh battery ready to go. That meant at least 300 full-power flashes without missing a moment.
What impressed me most was the range. From overpowering bright midday sun to dialing it down for moody, low-light interiors, the Stelos handled it all. Paired with high-speed sync, it gave me complete creative freedom to match the mood of each scene. Berlin was alive with trams rattling past and music drifting through the air, and the Stelos kept pace the entire time. It didn’t just light the scene — it became part of the performance.
Lighting power on the coast
Guernsey’s harbor, rugged seashore rocks, and Karl Taylor’s own studio became the testing grounds for broncolor’s newest light. Over several days, Karl put the compact 800 J unit through real-world scenarios — from braving breezes with a Para reflector to crafting precise studio setups. “Its size, its power, its flash duration, portability… even the fact you can charge it while using it — I’ve been blown away,” Karl says.
Karl praised its wide power range, rock-solid output consistency, and ultra-fast flash durations, freezing motion at speeds up to 1/15,000s. The LED modeling lamp, with adjustable color temperature, stayed visible even outdoors, adding versatility to both studio and location work.
When asked for his top features, Karl chose compact size, consistent power, and speed — with battery life as a close fourth. “This is going to be my go-to location lighting choice,” he concludes, reflecting on a week where one light lit harbor scenes, seashore portraits, and intricate studio shots with the same precision and reliability.
Where romance meets precision
In the grand gardens of a centuries-old estate, Yannick set out to create a story that merged romance and quiet defiance. Using a broncolor octabox 150 alongside the new Stelos light, he sculpted a scene where the soft blush of a flowing gown met the rich greens of the surrounding foliage. Every layer of tulle glowed with delicate precision, and the model’s skin took on a depth that felt timeless.
But Yannick’s vision wasn’t confined to the marble balustrades. Moving to the pond, he embraced the cinematic possibilities of the Stelos’s controlled output in open air. The dress floated like a dream, its ruffles spreading in the water as koi swam lazily beneath.
This was more than a fashion shoot—it was a study in creative adaptability. Working outdoors, Yannick used his tools not as constraints but as extensions of his imagination, tying the castle’s grandeur, the garden’s intimacy, and the pond’s quiet drama into one cohesive vision.
