Industrial-grade quartz flash tubes and a robust battery are housed in a rugged chassis built for demanding environments. The monolight accepts RFi and OCF softboxes, Profoto softboxes, umbrellas and hard reflectors, and performs well with large modifiers such as 4x6 ft and 5 ft Octa units.

It provides up to 250 full-power flashes per battery charge and lets you dial output from 0.8 to 750 Ws in 0.1 f-stop steps across 11 stops.

How does the battery interface limit flash performance in practice?

The internal battery caps you at 250 full-power pops per charge and governs the 0.01–2.3 s recycle window depending on the mode you select.
