Easy-to-use rotary controller and simple operation
Siros L is battery-powered
A single fully-charged lithium-ion battery stores enough energy for a Siros 400 L to flash more than 440 times – and it does that at maximum power! A miracle? No, quality!
Siros L is fast
In only 0.03 seconds your Siros L is ready again. The flash duration can last less than 1/9000 s (t 0.1) or 1/19’000 s (t 0.5). Truly miraculous times.
Siros L is simple
Very simple operation using the single rotary controller. Alternatively you can use the advanced, intuitive app. Either way using Siros L is fun.
Siros L is powerful
The high light output, up to 800 J, leaves no photographer standing in the dark – it can even challenge sunshine.
Siros L is LED
With its low power consumption, the 25 Watt LED module provides bright modelling light at a colour temperature of 3200 K. The light characteristics is absolutely comparable with the modelling light from a mains-operated Siros S.
Siros is Swiss
Do you appreciate quality? In Siros L you have Swiss precision and quality – inside and out. Be inspired!
Siros L is family
Proven meets innovation! The battery-powered Siros L, the Siros studio lights and Siros S are all available in both 400 and 800 Joule versions. Equipped with the Broncolor bayonet fitting, they are part of the best light system in the world.
Innovative Technologies | Made in Switzerland
Innovative technologies from the prize-winning Scoro and Move power packs have been adapted to the Siros L. These include:
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. That is convenience!
The second generation of our patented ECTC (Enhanced Colour Temperature Control) technology, which adapts flash voltage and flash duration to each other, ensures a constant colour temperature over the entire output range. Reliability at the highest level.
Enormous range of settings
With Siros L you have a free choice of 9 f-stops to set the flash output you need, all the way to 2 Joules. Photography with maximum freedom.
In Speed Mode fast charging and short flash times have absolute priority. In this case the calculation of constant colour temperature (ECTC) is suppressed. For quick results.
The latest lithium-ion technology in the batteries enables charging times never achieved before, and supplies energy for over 440 complete charges to full power – and all this from a weight of only 0.6 kg. It makes photography pure pleasure. Test the performance of our Siros L for yourself!

Applicants must be:
Aged 18 years or older from the application date
In permanent UK residence for a minimum of three years
Fulfil at least one of the following employment criteria:
In regular, permanent employment.
Retired from regular employment - With a minimum age of 50.
Not working through disability.
Note: All applicants will be subject to a credit reference check by the lender.
Credit is subject to application and status. Warehouse Express Ltd trading as Wex Photographic act as credit broker and not the lender. Barclays Partner Finance act as the lender.
Can I repay early? If so how?
No repayments are scheduled in the initial six-month deferral period. However, it is possible to pay off the loan, either by way of a lump sum or in smaller amounts. If the loan is fully repaid within the six-month deferral period, then no interest is payable, but a £29.00 early-settlement will be incurred. Such repayments may be made to Barclays Partner Finance by cheque, debit card or standing order. Unfortunately it is not possible to set up a direct debit within the deferral period. Further information on how to make such repayments will be set out in the loan agreement pack provided by Barclays Partner Finance.
What happens if I don't repay within the first six months (deferral period)?
Following the six month deferral period, Barclays Partner Finance will initiate a monthly direct debit payment for the remaining duration of the loan. Interest will be charged at a rate of 19.9% APR on outstanding balances (backdated to the first date of the loan). Late payment penalties and early repayment charges will apply from this point. Barclays Partner Finance will send a reminder letter approximately one month before the six month deferral period is due to elapse. Note: If you chose to spread the cost and pay monthly, interest is charged from the start of the loan, not from the start of the repayment period.
What will I receive from the finance provider (lender)?
Barclays Partner Finance will send a loan agreement pack approximately four weeks after delivery of the goods, confirming that the account has been activated and, from this point, it is possible to make repayments against the loan.
