The 800Ws Siros 800 L Battery-Powered Monolight from Broncolor is the latest in the Siros series of monolights. Powered by a lithium-ion battery, the flash head gets up to 220 full-power flashes on a 70-minute charge. The modeling light is a 25W LED to conserve battery power.

Speed is central to the design of the Siros L. Recycling is a lightning fast 0.03 to 2.7 seconds, while normal t0.5 flash duration is as short as 1/7400 sec. There's also a Speed Mode that bypasses the Siros L's Enhanced Color Temperature Control to prioritize short flash durations and fast recycle speeds. The result is a flash duration fast enough to freeze water droplets and other stop action effects. The Siros L has a 9-stop variable power range from full power all the way down to 2Ws. While at higher settings it's possible to out-flash the sun, lower settings allow use of even the widest apertures for your desired effect. All functions are available on the simple, intuitive panel via an ergonomic rotary controller, but you also have access to the menus and controls of up to 6 units using your tablet or smartphone and the free bronControl app.

Siros 800 L features Broncolor HS for syncing at shutter speeds up to 1/8000s. Broncolor HS requires an RFS2.2 transmitter, available for Canon, Nikon, and Sony cameras. Existing Siros owners should ensure that their lights have the latest user-upgradable firmware, available online at

Siros L is Battery-Powered

A single fully-charged lithium-ion battery stores enough energy for a Siros 800 L to flash more than 220 times, and it does that at maximum power.

Siros L is Fast

In only 0.03 seconds, your Siros L is ready again. The flash duration can as fast as 1/4400 sec (t 0.1) or 1/7400 sec (t 0.5).

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.

Speed Mode

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

Siros L is Simple

Very simple operation using the single rotary controller. Alternatively, you can use the advanced, intuitive app.

Siros L is Powerful

The high light output leaves no photographer standing in the dark. It can even challenge sunshine. And with a control range of 9 stops, you can still use wide-open apertures when needed.

Siros L is LED

With its low power consumption, the 25W LED module provides bright modeling light at a color temperature of 3200K. The light characteristics are absolutely comparable with the modeling light from a mains-operated Siros S.
