C1.2
RECESSED COFFER, LIGHTING DIRECTED CENTRALLY TOWARDS THE CEILING
2 rows of lamps type LT5-B5
An even higher light level is achieved using 2 rows of lamps in the same colour of white. Very pleasing effects can also be obtained with a mix of 2 different colours, either 2 different shades of white (warm white and cold white), or one shade of white with another colour (e.g. white and blue or white and red).
