In general, DMX values don't represent any real-world values. Most manufacturers just make 0 be the lowest output they can physically create, and 65535 be the highest, with some kind of linear or proportional scale in between. There's no reason to make the DMX value of 1000 match a particular Mirek, or any other value.
