I hope the Enscape team will change the lighting system of Enscape to the lighting system of Vray. Because Vray lighting is more accurate, they have Watt/ Lumens/ Color Temperatures. And most importantly they have " Mesh Light " that works very well. 
I agree with you that V-Ray lighting is very high quality, but also much more time & processing power-consuming than real time rendering. I do miss having lumens as an input value and I would also like to see more refined options for light power control.
Mesh lighting is very expensive in terms of render processing and is not likely to be included in real-time rendering as a light source. (see this topic for example Is this a lighting bug? How to solve it? Many versions have this problem.)
In the meantime, the self-illuminated material is a good option to recreate the effect in Enscape (albeit in conjunction with adding a point source to provide light output)
