Compliance
level
Floors should be wood, concrete
or ceramic tile. If floors are covered
with synthetic material, the relative
humidity should be at least 30%
Mains power quality should be that
of a typical commercial or hospital
environment.
Mains power quality should be that
of a typical commercial or hospital
environment.
(>95% dip in U ) Mains power quality should be that
T T
of a typical commercial or hospital
(60% dip in U ) environment. If the user of the
T T
model TL 50 requires continued
(30% dip in U ) operation during power mains in-
T T
terruptions, it is recommended that
(>95% dip in U ) the TL 50 daylight therapy lamp is
T T
to be powered from an uninterrup-
tible power supply or a battery.
