The OC-OF7 Octa Fluorescent 7 Socket Fixture from Raya is a 7 Edison socket base that accepts five 50W CFL fluorescents with a combined wattage of 350W. The sockets handle up to 105W, but the fixture is limited to 2 lamps of that wattage due to their size. The OC-OF7's base has dual rocker switches, each of which control on/off function for 3 or 4 lamps allowing the creation of a light ratio. The Octa OC-OF7 has a multi-voltage power supply for worldwide use and has a standard 5/8" receiver for light stands and accessories. The OC-OF7 can also be combined with the optional Raya OC-OSB80 32 Octa Softbox, which has been custom designed to modify the light output of this fixture. Limited 1-Year Warranty
