Optimal light spread

Shaping light is at the heart of every great image you create.

Your choice of light shapers

Engineered to use the newly developed Elinchrom OCF modifier mount, the Elinchrom ONE is also compatible with most Profoto bayonet light shapers, greatly expanding your selection of available light shaping tools.

Engineered for peak efficiency, its 131 Ws of capacity generates a light output usually seen in 200+ Ws units. At 1 meter (3.3ft) and 100 ISO, the ONE can achieve F-11.9, with the Diffusion Dome attached, and when combined with the HP Reflector, the achievable F-Stop climbs to F-45.2.
