They’re powered by an interchangeable 28.8 volts lithium-ion battery which gives up to 440 flashes at full power for the 400 joules model and 220 flash with the 800 joules version. Full recharging takes just 75 minutes. These new monoblocs are exclusively battery powered, but like Profoto’s B1, with the battery housed internally, operation is entirely cable-free.
The Siros 400 L and 800 L employ Broncolor’s ECTC (Enhanced Colour Temperature Control) technology – as also used in the Scoro and Move power packs – enabling a fast flash duration of up to 1/7400 second (t0.5) with constant colour temperature stability over the full output range. Recycling times can be as fast as 0.03 seconds. In the monoblocs’ Speed Mode the flash duration can be as short as 1/19,000 second, but without the ECTC-controlled colour stability.
A 25 watts LED-type modelling lamp is fitted and balanced at 3000 degrees Kelvin to match the halogen modelling lamps used in the mains-powered Siros monoblocs.

The Siros L models are compatible with the entire range of Broncolor light-shaping accessories. Availability is from early July and will include various travel kit options. Local pricing is yet to be announced.
