If, however, a lamp has temperature-sensitive electrical characteristics (e.g. a fluorescent
lamp), or if the ta rating of the luminaire exceeds 30 °C, the ambient temperature within the
draught-proof enclosure shall be within 5 °C of the ta rating and should preferably be the
same as the ta rating.
