Size & Weight

Surefire M600DF and Modlite 18650 bodies are very much identical as far as dimensions go.

The Modlite has slightly different machining profile without lot of markings on the body. Both light bodies feature scout mounting footprint to accept mounts that are already available on the market. 

The weight of both lights are pretty much the same, and Modlite is just 0.3 oz heavier, and it's not significant enough to feel the difference if the light is the only accessory you have on the firearm.
