Priolite MBX500 Flash Head
Sorry, there are no more available.
The Priolite MBX500 Flash Head is a real step-forward in lighting technology, featuring 500 Watts of flash illumination and a slide-in battery pack, yet weighing only 3.2kg (approximately 7lb). The internal, swappable battery unit offers enormous flexibility and is far more convenient than carrying separate external battery modules. The battery pack is safe and easy to handle, although you may never even need to remove it, as the head can be powered and the battery charged via a mains lead. The Priolite offers a bright, easily visible display for adjusting the flash power settings and is adjustable in 1/10 f-stops using a turning knob. The head is already prepared for radio operation with built-in remote control modules. As the Priolite MBX500 is powered by a battery pack inside the light head there is no need for cables, making them highly versatile and portable to meet the needs of the demanding studio photographers of today.
May 2013 - The Priolite has thrown us a new piece of technology and thus introduced a whole new way of working in the studio. Bold claims I hear you say? Well, after you’ve read this you can make your own minds up about that, but first lets go through the nuts and bolts. Read more... »

Are you eligible for finance?
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.
