Simulating Daylight isn't very easy, especially not with LED diods. https://vgl.ict.usc.edu/Research/OptimalLED/ There was a lot of research in covering the daylight spectra by adding additional LED diods to get close to daylight. Coming from a filmset background, usually strong metal Halide lights are used only to simulate a daylight scene, for example the arri daylight 18, which is using a Metal Halide 18000 Watt bulb.Attached outside of windows. Furthermore light sources (except for lasers) drop intensity quadratically, meaning the size of your room is a big factor. Talking about LED's, even on shoot's like the "mandalorian" where the main light source is a LED-WALL, the light isn't enough so that additional Studio lighting is added.
