The Siros L 800Ws Battery-Powered Monolight  from Broncolor is the latest in the Siros series of monolights. Powered by a Li-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 of 1/18,000 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 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 www.bron.ch/sirosfirmwareupdate/.

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 1/8700 sec (t 0.1) or 1/18000 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.

Kinda flimsy…
Thought the assembly was metal, it’s some kind of PVC.

Fantastic for furniture making
Size: 16 x 18 Inch, Size: 16 x 18 Inch
Frankly, I didn't know what to expect... But these turned out to be exactly what I was looking and hoping for. These table legs were so easy to assemble. They come with adjustable feet so you can have a level table no matter your tabletop shape or floor situation. Assembly is done with a simple Allen key. Printed instructions are included with simple diagrams that are so easy to follow. Also, the seller provided all the hardware needed and more! They provided multiple black screws of different sizes that fit through the top holes of the legs, making it so easy to screw the leg base into the table top (use an electric drill with a Philips head for that). I had zero issues with any of the hardware provided. The base has a nice smooth black powder coat application on the metal. Shipping was so quick too. Seriously, if you are looking for a low cost, easy to assemble, good looking, and adjustable end table base, get this. I ended up making plant stands with these using some tree slices I had as you can see in my photo. 10/10 highly recommend.

Easy to put together
Size: 16 x 18 Inch
Great legs and look great with the table, however, the legs connect to a peak and is not level. A friend made me some spacers on his 3d printer so I could use them.
