The 5.5" Magnetic Reflector for FJ400 & FJ800 Flash Heads from Westcott has a widely-used Bowens S-type mount that quickly attaches to the strobe. Its reflective silver aluminum interior maximizes the flash's output and allows it to be thrown at appreciable distances. A handy convenience feature is the magnetized lip around its diameter that accepts and holds magnetized Westcott CCT gels.
