Broncolor’s New Siros L Promises 440 Full Power Flashes on One Charge

Today, Broncolor is making a new addition to their super high end lighting in the form of the Siros L. They’re billing it as a light for photographer who want no compromises.

For starters, it’s boasting lithium ion tech, ECTC tech, and can produce 440 full power flashes on a single charge. Beyond that, it’s also got a flash duration of up to 1/19,000 and promises consistent color temperature output through the entire range of its power.

More details from the press release are after the jump.

Siros L is a true Broncolor unit, produced for ambitious professional photographers who do not want to make any compromises. Most modern lithium ion technology paired with the ECTC technology known from our high-end power packs makes it possible: 440 flashes with full power, flash duration up to 1/19,00 (t 0.5) and, of course, guaranteed constant color temperature over the entire control range.

Siros L is an absolute mobile unit, either outdoor or on location and corresponds with the photographer’s need for more mobility. However, Siros L can also be optimally used as an additional unit with a Broncolor studio equipment. The 25 watt LED modules offer a bright modeling light with a color temperature of 3000 K. The quality is comparable with the modeling light of our AC powered units.

From the sales launch, Siros L will be available in two power levels, 400 joules and 800 joules. The 400 J version with the smaller dimensions and weight is the option for photographers who are often on the move. The 800 J version is made for photographers who refuse to compromise also with regard to power.
