The 11R is a bright, highly focused reflector, providing very high output, direct lighting. With its long throw and narrow 50º beam spread, the 11-inch reflector is excellent for sports photography, illuminating subjects over a greater distance with high intensity. The 11R will fit in place of the standard 7-inch reflector on all AlienBees flash units, measuring 6.25 inches deep, and 11 inches in diameter.
