Siros L is battery-powered

A single fully-charged lithium-ion battery stores enough energy for a Siros 400 L to flash more than 440 times - and it does that at maximum power! A miracle? No, quality!

Siros L is fast

In only 0.03 seconds your Siros L is ready again. The flash duration can last less than 1/9000 s (t 0.1) or 1/19'000 s (t 0.5). Truly miraculous times.

Siros L is simple

Very simple operation using the single rotary controller. Alternatively you can use the advanced, intuitive app. Either way using Siros L is fun.

Siros L is powerful

The high light output, up to 800 J, leaves no photographer standing in the dark - it can even challenge sunshine.

Siros L is LED

With its low power consumption, the 25 Watt LED module provides bright modelling light at a colour temperature of 3200 K. The light characteristics is absolutely comparable with the modelling light from a mains-operated Siros S.

Siros is Swiss

Do you appreciate quality? In Siros L you have Swiss precision and quality - inside and out. Be inspired!

Siros L is family

Proven meets innovation! The battery-powered Siros L, the Siros studio lights and Siros S are all available in both 400 and 800 Joule versions. Equipped with the Broncolor bayonet fitting, they are part of the best light system in the world.

Innovative Technologies | Made in Switzerland

Innovative technologies from the prize-winning Scoro and Move power packs have been adapted to the Siros L. These include:

Cut-off technology

Flash duration and light output are the two decisive factors in light control. A microprocessor in Siros L will calculate the shortest flash duration for a given energy setting. That is convenience!

Constant colour

The second generation of our patented ECTC (Enhanced Colour Temperature Control) technology, which adapts flash voltage and flash duration to each other, ensures a constant colour temperature over the entire output range. Reliability at the highest level.

Enormous range of settings

With Siros L you have a free choice of 9 f-stops to set the flash output you need, all the way to 2 Joules. Photography with maximum freedom.

Speed Mode

In Speed Mode fast charging and short flash times have absolute priority. In this case the calculation of constant colour temperature (ECTC) is suppressed. For quick results.

Lithium-ion battery

The latest lithium-ion technology in the batteries enables charging times never achieved before, and supplies energy for over 440 complete charges to full power - and all this from a weight of only 0.6 kg. It makes photography pure pleasure. Test the performance of our Siros L for yourself!

Interest will be charged at a rate of 18.9% APR on outstanding balances (backdated to the first date of the loan).
