22 Poul Henningsen 1928: med indførslen af det elektriske lys har vi gennemlevet en opløsning af rummenes møblering, som svarer til varmespredningen ved overgang fra kakkelovn til radiator. Hverken varmen eller lyset har generelt fundet den kvalitet, det havde før de moderne installationer... with the introduction of the electric light we have passed through a dissolution of the rooms' furnishings, which corresponds to heat diffusion in the transition from the stove for heating. Neither heat or light has generally found the quality it had before the modern installations

We use very much shade to discover objects and to make the interior beautiful at night, the furniture and large objects must cast distinct, but not too sharp shadows. There is never painted anything interior of any painter, where the shadow not of the utmost importance for the image Poul Henningsen
