Pose des lanterneaux [...] nous avons discuté des fenêtres ordinaires, mais que dire des lanterneaux (fenêtres de toit)?

Lanterneau : Noter que les grands dictionnaires donnent un sens restreint au terme "lanterneau" (voir la fiche "lanterneau/lantern light"); mais le concept ayant évolué, l'usage a précédé les dictionnaires et a étendu le sens de "lanterneau" à tout dispositif constituant une prise de jour en toiture. 11, record 1, French, - lanterneau

Puits de lumière : Hormis la publicité et la langue parlée au Québec, "puits de lumière" ne trouve pas d'attestation dans son sens concret et général entendu ici (voir la fiche "skylight/prise de jour en toiture"). Cependant son usage répandu et l'absence d'un terme véritablement propre nous semblent justifier parfaitement son emploi. 11, record 1, French, - lanterneau
