California light works

Just put these up yesterday should I leave them in this direction or turn them 90° I mean I think it would matter consider it supposed to cover a 4 x 4 and yes I know the third is overkill but I want it anyways

The manufacturer states 4x4, when I ran them they covered a 2x4 area each well.

I’d personally want at least 2 more in the space you have.
