Playing with light blocks

I was messing around with light blocks and then I found that I could make some really cool gradients(they were brighter in game)

In the last photo I made two of the light blocks that covered the ceiling 1 level brighter and I wondered if this was a better way of shading like the underneath of a skylight maybe using tinted glass. Because it did give the impression that there was a hole in the ceiling but with realistic light not Minecraft’s spread out shading
