Technical Data
Light intensity on optical axis
The effective light intensity for bilirubin dissociation (E
depends on how far away the lamp housing (lower edge)
is.
If a higher intensity of light is required, the white light
lamps may be replaced with blue phototherapy lamps (by
trained service personnel or DrägerService). The hours
used by the two additional phototherapy lamps will not
be registered by the hour meter.
