5.9 Changing the bulb
LED
The devices in the OSF-4 series are all fitted with LED bulbs.
Due to the long service life of an LED lighting system, for these microscopes it will
not be necessary to simply change a bulb.
Problems with the lighting unit would therefore, in most cases, be caused by defects
in the electrical system. If this is the case, then our Technical Service will be able to
help.
