Broncolor Siros 800 L overview

  • 1Description

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 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 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 440 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.

Broncolor Siros 800 L reviews

Siros L 800Ws Battery-Powered Monolight is rated 4.7 out of 5 by 12.
Rated 4 out of 5 by from Great light but a wee bit annoyed So far I like the Siros! True high speed sync (without rapid pulsing) and the ability to control it from a smart device is huge! However, I do have a bone to pick with Broncolor. One of the reasons I went with the Siros L was the RFS 2.2C's hot shoe. I thought, and was told, that I'd be able to attach a Canon ST-E3-RT to the RFS hotshoe and, at least, be able to trigger my speedlites. Oh so very wrong! If that wasn't an issue, I'd have given the Siros 5 stars. I even got that mistaken impression from B&H. This issue isn't a deal breaker. Maybe an improved RFS 2.X C that deals with this, maybe? But, a straight answer on this BEFORE PURCHASE would have been a lot nicer.

Rated 5 out of 5 by from Expectations met I have had this wonderful light for nearly a year now and it has been an overall pleasure to use.� I am a Commercial Photographer where majority of my shoots are on location.� Up until now my lights have all been Elinchrom and stepping up to the Siros 800L has just simply, made my location shooting life and post production much easier.� Recycle times, color consistency, power output consistency all live up to the Broncolor hype.� Living on a small island that is predominantly Profoto in the High end flash scene, toting around Broncolor is nice. The stand mount has a very small window in between free moving and locked down.� You will have to be mindful if you want to be able to adjust the angle without loosening the lever first.� For such a heavy monolight it is very well balanced due to the forward placement of the stand mount and it's rear heavy design.� I have put a Metal 22" Beauty Dish 4'x6' Brolly Box, and a 60" Octo on it with no problems whatsoever.� Just make sure you are using an appropriate stand with a sand bag or 2. The modifier mount is something to get used to.� Once locked in, the modifier can freely rotate for a near 360 degrees.� It helps when you want to rotate a softbox, and you can lock down your speedring insert in the ring to make that more stable.� It could be improved if there were a way to lock down the insert on the light side to prevent inadvertent rotating of the modifier, which will happen if you move the light around. The RFS 2.2 is not the most impressive trigger I have used.� Godox makes a virtually identical trigger for Speedlights.� Go figure.� Used only at short distances of under 30 feet it has performed flawlessly.� Light pops every time I want it to, and only when I want it to.� The Hi-Sync is no joke.� I have taken outdoor photos of a 300 person High School Graduating Class (60 feet away on risers) with just the included reflector and at 1/2000sec (gotta have those blue skies) , output at 400J and overexposed by 1/3 stop.� Interface is rudimentary and a word of caution; if you change settings like Hi-Sync and speed mode on the light and not by using the remote, the changes will not be reflected on the remote until you do so manually. The included bag is great.� well padded with a few extra compartments that fit the charger, an extra battery or 2, light meter, speedring and a few other small accessories.� 2 long sections along the side and one small compartment at the end of the bag.� Other reviewers are correct that there is no real way to secure the closure.� Double zippers pulled simultaneously with a Velcro strip to "secure" the flap. My only real gripes are that there is no AC "dummy" battery available to use the light plugged into a wall outlet if I am shooting indoors and do not require the use of the battery; and that the modeling light has no dimming option.� Either it is on full power or completely off.� The modeling light is a much warmer color than the flash tube as they state.� If your subject is close to the light you will get a very warm cast from the modeling light.� Works great as a quick CTO replacement in a pinch and at close range. I agree with other reviews in saying that this light is not built for use in inclement weather.� Yes the housing is solid metal and feels really tough.� But the air vents are on top and no mention or visual sign of any weather resistance.� Keep it out of the rain! Just for everyone's knowledge, this light will NOT fit into a Think Tank Logistics Manager or the Production Manager 40 sideways with the included Siros Umbrella reflector and cover installed (even with the front cover taken off).� I have both bags and I have to situate the light the long way in the bag.� Bit of a bummer.� Seems like the Siros 400L would fit width wise due to it's slightly shorter length.�� This concludes my lengthy review.� I don't write many reviews, but this one deserved a thorough one.� I hope this helps you make a more informed decision on buying this light.

Rated 5 out of 5 by from Excellent product and beyond my expectations !! This item worked perfect out of the box. I've never owned a monolight before. I've alway shot with my SB-700 ( 2 ) and pocket wizards TT5, but I wanted to have something more powerful, more practical, be able to freeze action and also, be able to shoot several flash per second. TTL is great for moving subjects but at the same time, it is sometimes very inconsistent. I decided not to go with the Profoto B1 or D2 because neither are compatible with my Nikon D500. The B1 is just 500 Ws and the D2 is not battery powered. Also, I did not want to continue using TTL because I wanted to be able to control my light the way I wanted, under any ambient light condition. Beside, the Profoto are very expensive products, so I decided to turn my sight in another direction and the new Broncolor Siros 800 L, had my attention. This item is powerful, simple to use, practical, elegant and it is compatible with my two Nikon cameras : D750 and D500. Despite its price is higher than the Profoto B1, it is an 800 Ws in compare to the 500 Ws of the B1. I tested this item last night using HS. I was able to shoot at f/1.8 and f/2 ( using my Nikon 50mm f/1.8 lens ) and 1/8000 of a second without any problem at all. This product is advertised to shoot up to 50 flashes per second in Sequence mode and let me tell you, you do not need the Scoro pack at all ( which by the way, the price is $14k ) to be able to trigger several flashes per second. The only thing you need to do if you want to shoot several flashes per second is : setup your Siros to Speed mode or HS and make sure that your camera is in Rear Curtain mode and problem is resolved. I tried to shoot several flashes using the Sequence mode in the unit but it did not work at all; the solution is to setup your camera to Rear Curtain and you will be able to shoot as many flashes per second as you keep pushed down your camera shutter speed. Voila !! Now I do have a unit that have as much power as probably six SB-700 flashing at the same time, more power than the Profoto B1, no TTL and capable to shoot as many flashes per second without any hiccup. I can shoot at any shutter speed that I want and at any aperture and I can control my light output, as I wanted. Excellent !! Is it heavy ? Yes, but for me, that is not a drawback. B&H customer service is so good that before I placed my order, I talked to one of the representatives to find out if there was any heavy duty light stand that could hold this unit secured; he suggested right away to go with the Impact LS-96HAB for just $55 dollars. This stand holds 22 pounds and it goes up to 10 feet high. Well done B&H and thank you for keeping such an excellent customer service team. I do recommend this product to anybody. Despite the price is a bit more than the Profoto B1, the Transceiver RFS 2.2 is just $112 dollars in compare to the more of $400 that you need to pay for the Profoto remote control. Also, my Siros was already updated to the most recent firmware and the bag provided, has the right measure to be carried as a hand bag when you travel by air. Highly recommended !

Rated 5 out of 5 by from Siros L My camera is an older Hasselblad 205TCC using 120 size film. CF lenses I'm limited to 1/500 flash sync. Shooting during the day requires me to use filters to darken the ambient light when wide open aperture thus needing a more stronger flash and 800ws is just right. TTL is not available but I prefer to meter my exposures anyhow, so I don't need it. When wanting to use a speedlight for fill or background it's possible with an additional RFS 2.2 trigger connected with the speedlight. Studio lighting is all Broncolor, so all my light modifiers will work. With the Glass frosted in the front and clear on the sides, light is much better for filling around the light rather than just straight forward such as a speedlight would do.

Rated 5 out of 5 by from The light that goes with me... I love it! Powerful moonlight you can throw into a backpack and hike with. Works great indoors, of course, but on location it has no peers at the moment.Opens up entirely new class of creative possibilities.Quality of light is awesome, and it goes bare bulb if needed. The body design is great - nothing sticks out, protective cap covers the flash tube for safe transport, and it can be packed into a really small volume. Build-in radio trigger works well. It's not TTL, but who cares. I'm excited!

Rated 5 out of 5 by from I am planning to buy another one ! This is a great strobe. Worked as it should out of the box. Easy to manage, well built, elegant and it does include a nice bag to store it. You won't have TTL but this function is tricky and sometimes inconsistent. If you want to control your light 100 % and consistency, this is the answer. Setup the strobe in speed mode, lower the power between 3-5, setup your camera to Ch ( in my case my D500 to 10 fps ) and TTL and start firing up as many flashes that you want. It is simple and amazingly fast. Use the sequence ( up to 50 flashes per second ) to shoot as many flashes per second in a single frame shot. Depending of the power output, your battery will fire ( in theory ) up to 220 flashes per full charge. I can tell that I was able to shoot almost 200 flashes and still my battery was 50% charged but I was not using the full power at all. It is a bit heavy and you would have to have a very sturdy light stand to avoid any accident. Highly recommended !

Rated 4 out of 5 by from Fantastic light but fragile for travel So in what is probably an ironic twist is that this battery powered light is amazing but doesn't travel very well. The dish/cap that serves as the protector for the head fits loosely and is plastic. TSA didn't put the head back exactly as I had in my case (not the Bron case) and the dish broke a tab. This meant that the protective glass broke and so did the flash tube. This was a $400 repair.� The good news is the flash tubes are less than the Pulso tubes, but the weakness of the primary flash tube protector makes me worry about traveling with them more without figuring out a way to support the head/cap so it won't break again. I think if the cap had a foam disk glued in that would take up the space between the dome and the dish you'd buffer and support the whole thing. You'd then need a way to support the outside dish or give up and use an older style flash head cap.� Outside of this teething issue I'm thrilled with the light and will be replacing several packs with more of these heads. The light is traditional Bron which is to say perfect and the heads take the many modifiers that I already own. The battery works great giving very close to the reported number of flashes and the High Speed sync works well on the RFS remote - which is much better than my Pocket Wizards. I found HS significantly cut the output of the strobe when stopping down via shutter but perhaps there's a way to tune that. Nonetheless it worked and being able to adjust the power (which isn't intuitive but is accurate) was a boon when the head was in a Para 10' over my subject.� These are the lights location shooters have been waiting for - or at least I've been waiting for. I'd like them to be more durable so they get knocked a star but otherwise they're perfect.

Rated 4 out of 5 by from Siros L Does It Right! But, ... I absolutely love this unit: both the light it produces and the almost hands off flexibility it gives me. Being able to carry this much power and quality light around makes location shooting fun! Broncolor also chose to do HS the right way, IMO. There are some things, though, that I hope Broncolor can address in the form of software updates: - Adjustable modeling light output. Full and proportional power settings - Transceiver trigger so I can read the power setting at camera position - If it's portable and costs $2000+ it should be weather sealed - The control area should be better recessed in case of fall. I was lucky mine fell on something soft. Also move the sync socket, mini-USB and mains switch - E-TTL and a Sekonic radio module would be niceties but not necessary
