Keep a low profile
Add the flexibility of off-camera flash and light shaping to your kit without adding unnecessary bulk. Similar in size and weight to a 70–200 mm lens, the Elinchrom ONE is easy to carry and easy to keep close, whether you are travelling light, working on location or building a smaller everyday setup.
Built for location work
The integrated Li-Ion battery keeps the Elinchrom ONE compact and easy to handle while also improving protection for outdoor use. Because charging happens via USB-C, you are not tied to proprietary chargers or spare batteries. Charge from mains power, a power bank or another compatible USB-C source and keep your setup simpler wherever you work.
Keep moving without interruption
With up to 725 full-power flashes on a single charge, the Elinchrom ONE is ready for longer shoots. Active Charging also allows you to continue shooting while connected to a power source, regardless of battery level. It is a practical feature for photographers who want fewer interruptions and more freedom during the shoot.
Shape your story
Light shaping is central to creating more deliberate images. Designed around an exposed flash tube for broad and even light spread, the Elinchrom ONE delivers the light quality Elinchrom is known for. It gives you a strong foundation for building clean, controlled light in a wide range of situations.
Your choice of light modifiers
The Elinchrom ONE is built around the Elinchrom OCF modifier mount and is also natively compatible with most Profoto® OCF light shapers. This gives you access to a broader range of tools without making your setup more complicated. The included Elinchrom OCF to Bayonet Adapter also allows quick mounting to reflectors and speedrings that use the traditional Elinchrom bayonet.
Do more with less
Engineered for efficiency, the Elinchrom ONE uses its 131 Ws output to deliver performance that competes well beyond what its size suggests. At 1 metre and ISO 100, it reaches f/11.9 with the Diffusion Dome attached. Combined with the HP Reflector, output increases up to f/45.2. The result is a compact light that remains genuinely useful across portraits, products, events and location work.
Navigate quickly
The touchscreen interface and updated menu structure are designed to make setup faster and daily use more intuitive. Adjust settings quickly, move through menus with less friction and keep your attention on the image rather than the equipment.

Product FAQ
Yes. Elinchrom ONE and THREE have built-in Bluetooth and can be controlled via Elinchrom Studio Software as well as the iOS and Android apps. They also include a built-in Skyport Bridge, allowing them to communicate automatically with older Elinchrom flashes that can also be controlled from smartphone and computer.
Active Charging allows you to charge the battery while shooting. On ONE and THREE, charging happens via USB-C, which makes it possible to use a USB-C power adapter or power bank to charge the built-in battery while the unit is in use.
To lock the touchscreen on the ONE and THREE, press the ON button while turning on the device for 9 seconds. A lock symbol will confirm that the touchscreen is locked. To unlock it, turn the device off and on again.
Yes. The built-in LED light on ONE and THREE works well for film and video production. Light quality is high, helping colours and skin tones reproduce more accurately. Brightness can be adjusted, and colour temperature can be set in fixed steps from 2700 K to 6500 K. Output is approximately 3000 lumens, equivalent to roughly 120 W halogen light.
ONE and THREE use an OCF mount as standard, giving access to a wide range of light shapers from different manufacturers. An Elinchrom bayonet adapter is also included, which means the full Elinchrom light shaper range can be used as well.
Yes, the battery can be replaced through service. In practice, this is a question more often asked by prospective owners than by long-term users, since battery capacity and battery life are strong parts of the product. The built-in battery offers high capacity, and advanced battery management helps support long service life. Combined with Active Charging via USB-C, it gives ONE and THREE a flexible and dependable power solution. Tip: always recharge the battery after shooting. A fully discharged Li-Ion battery can be damaged if left without maintenance charging for too long.
