Elinchrom has launched its new Elinchrom ONE portable off-camera flash. The ONE is intended to be a true go-anywhere light source, weighing just 1.5kg / 3.3lb, measuring a similar size to a 70-200mm lens, and featuring extensive weather protection.

A major part of the incredible compactness and low weight is the ONE's internal Li-ion rechargeable battery. This has the capacity for 725 full-power flashes on a single charge and can be recharged from any USB-C power source, eliminating the need for spare batteries or chargers. What's more, with Elinchrom's Active Charging feature, the battery can be charged while the flash head is in use, regardless of the battery's charge level.

The ONE's flash tube is unconcealed to boost light output and enhance beam spread, and can be fitted with Elinchrom's newly-developed OCF modifier mount, enabling the use of most Profoto OCF light sharpers like spill-kills, barn doors and brollies.

Although max light output is quoted at a relatively low 131 Ws, watt seconds is a measure of power capacity rather than light output. Elinchrom states that actual measured light output from the ONE is equivalent to the illumination from most 200+ Ws flashes. At 1 meter (3.3ft) and 100 ISO, the ONE is rated to achieve f/11.9. With the Diffusion Dome attached, and combined with the HP Reflector, Elinchrom claims the achievable f-stop increases to f/45.2.

Other noteworthy features include an easy to read touch-screen rear panel and newly-designed menu interface to simplify settings adjustment, while a bi-color LED modelling lamp can output 3000 lumens, with color temperature adjustable between 2700k and 6500k at a CRI of 95.

High speed sync of up to 1/8000s is also available to help freeze motion or overpower ambient light, and the ONE incorporates intelligent Pro-Active cooling that learns your shooting style and adapts cooling for maximum effect at minimal noise levels. Even the tilt head is removable, making the ONE more suited to hand-held use.
