Hi, fire up FNVEdit and filter by "show conflict users". Watch out for conflicts in RWELE Imagespace records. In my case the fnvlodgen esp overwrote a cell with record NVExterior (or something similar) with WaselandExterior (or something similar). Make sure that Imagespace Settings from RWELE are not changed by any other mod, especially fnvlodgen (either by putting rwele at the very last position in your loadorder or by manually putting an override entry into your bashed / merged patch). This should fix the brightness issue.
