If size and weight are your primary deciding factors, the Ikelite DS51 II 50W TTL Underwater Strobe is for you. The DS51 II is one of the smallest and lightest strobes in its class, weighing less than one pound per strobe. The compact size makes it simple to position the strobe for macro, super macro, and close focus wide angle. The strobe power/exposure mode switch is prominent on the rear of the strobe with a bright white detail that makes it easy to see where it's pointing. When used in TTL mode together with a compatible TTL converter, your camera will meter the scene and adjust strobe power automatically.
