UE4 Sequencer project Relighting - CGMA Art of Lighting for Games week 7-8

Relighting practice I did during CGMA Art of Lighting for Games weeks 7-8. Completed in ~20 hrs from scratch. Based on Sequencer project from UE sample projects.
On this project I decided to perform experiment with physically correct values and exposure. I used parameters of a real OSRAM tube light with size similar to ones in the scene. Warm lights have 800 lm brightness, 4000K temperature an IES profile provided by manufacturer (except Epic sign light). Most real-world cold lights have color temperature 6500K, but I had to use 7500K to achieve desired color contrast.
As a reference I used subway fight scene from "The Matrix". I also found behind the scenes short to check how lighting looked before color grading. Using behind the scene shots I generated LUT to match these shots to shots from the movie. In UE I replicated lighting similar to behind the scenes, then used LUT with some fine-tuning to make my scene look matrix-alike, but fit in the given project.
As a side experiment I wanted to use as few lights as possible - environment is lit only by 5 omni lights and 2 spot lights - this exactly matches the light source count featured in the scene - no extra lights at all. Of course, character lighting utilizes additional lights per shot.
