Is this Iray lighting? If so, you need to create a spotlight, then change the geometry shape and size. For example, if you change geometry from the default Point to Disc, then increase the size from the default 10 to 100 (ie. 1 meter), that gives you a large disc which will cast diffuse shadows. The smaller the disc size, the harder the shadows will be.

Works great! Thank you :) What exactly are those parameters (particularly changing it to disc) doing though?
