Broncolor Siros 400 L WiFi / RFS2.1 inc. Flash Bag 1.1

With the latest lithium-ion technology, a single battery, in spite of its very compact size and low weight, can charge a Siros 400 L up to full power 440 times! Reduce the output, for example by just 2 f-stops, and you can have over 1700 flashes! The results will convince you.

The battery can be used over a very wide range of temperatures – from −10°C to +60°C degrees Celsius. This gives you a free range of locations – at the North Pole or in the desert, Siros L is your reliable companion.
When discharged, this high-quality battery takes only 70 minutes to fully charge again. In Siros L too, the ECTC technology you know from our high-end Scoro and Move power packs controls the flash curve, enables flash durations from 1/19’000s (t0.5). In addition, it guarantees constant colour temperature over the entire control range.
