Quote - Question for the light boffins: using a meshlight (RealityLight), is it quicker than a material converted to light?

I'd say thats a factor of the converted surface shape and enviroment, propbably the most efficient being an internal white sphere surface or white ibl.  

Not good in photogenic character though.  I come to beleive that attempting to max out efficency in lighting, detracts a lot form the image atmosphere
