Siros 400 L Battery-Powered 2-Light Outdoor Kit 2 was put together by Broncolor to give photographers studio quality lighting on the road free from power cords and sync cords. The kit includes two Siros 400 L flash heads, two Li-Ion batteries, a charger, a silver/black umbrella, a softbox with adapter ring, a sync cable, and an Outdoor Trolley Backpack.
The Siros 400 L Battery-Powered Monolight is the latest in the Siros series of monolights. Powered by a Li-ion battery, the flash head gets up to 440 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 400 L. Recycling is a lightning fast 0.03 – 1.2 seconds, while normal t0.5 flash duration is as short as 1/6200 sec. There is 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 of 1/19000 of a second at minimum power: 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 400 L features Broncolor HS for syncing at shutter speeds up to 1/8,000s. 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 www.bron.ch/sirosfirmwareupdate/.
