| It is seen clearly that conventional
tubes not only distort colours but do not emit UVA radiation which is
crucial in all biological functions of plants and animals.
In contrast to this full spectrum tubes - as used in INSTANTDAYLITE° - follow
very closely the data of natural daylight in colour rendering, in colour
temperature and last not least in the all important UVA share of sunlight.
