The GF400 Portable Flash System provides 360° illumination and boasts 400 Ws power output with 80 m Guide Number. It is capable of wireless-remote manual power control when used with the Genesis Wireless Trigger kit (sold separately).

Key Features: Calumet GF400 Portable Flash System

The GF400 gives you excellent manual control of flash settings with compact form and ease of use. It features intuitive controls, a rotating head with 90° tilt capability, and removable reflector. This system has 7-stops of variable output from 1/128th to 1/1 power in 1/3-stop increments. Recycling time to full power is 4 seconds and the flash duration time is 1/300-1/10000 seconds. The GF400 features 5 different flash modes (Manual, S1 & S2 Slave Triggering, RPT Stroboscopic Flash, and Hi-speed Sync Triggering), and comes with an off-camera adapter base.

What makes this flash system exciting is the wide range of light control accessories available, including a 16-channel wireless trigger kit, an umbrella reflector, beauty dish with grid and snoot, to name just a few. Additionally, all Genesis light modifier accessories are compatible with the Quantum Qflash TRIO & 5dR flash units.

Other notable features of the GF400 include a large LCD display, simplified controls, a separate ON/OFF button, rotating head with vertical adjustments up to 90°, MF-Assist Beam (ideal for low-light or low-contrast conditions), Audio Ready function, and built-in overheating protection circuitry. Built-in PC sync and 3.5 mm sockets also provide flexible triggering options.

Each GF400 portable flash system includes a flash, flash tube, reflector with diffuser, power cable, 3 m (9.8 feet) 3.5 mm sync cord, mini-stand, an off-camera adapter base, protective bag, user manual, and is backed by a 1-year warranty.

The GF400 is designed to be used with Gensis PowerPort Duo 1000, and is compatible with a wide array of lighting accessories, including the Genesis Wireless Trigger Kit.

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.
    • Self-employed.

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 Photo Video 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.
