Introduction
Thank you for choosing the Impact FF-OF4 Octa 4-socket
uorescent xture; a compact and portable lighting xture
that uses Edison-base compact uorescent lamps (CFL)
up to 85 W per socket. It is ideal to use when a soft and
diffuse light source is needed. When tted with the Octa
Softbox FF-OSB60; the FF-OF4 will also provide excellent
round catch-light lighting.
Two rocker switches on the back panel provide control
over the selection of your lights, while the low operating
temperature of uorescent bulbs lets you comfortably
place the lights closer to your subject without discomfort.
The FF-OF4 mounts on any 5/8” stud, and its built-in
umbrella socket provides another lighting option. Multivoltage circuitry (100~240V/50/60 Hz), allows you to plug
in the FF-OF4 anywhere with the correct plug adapter (not
included).
The FF-OF4 offers a practical and economical solution
for digital lighting applications in studio, home, or ofce
locations.
