Olympus BX53M Instructions Manual page 11

CAUTION - Halogen lamp housing / Mercury lamp housing -
Confirm that the lamp is attached properly and cords are
connected properly.
Remove the power cord from the product when replacing the lamp.
To avoid electric shock hazards and burns when replacing the lamp, set the
main switch of the power supply for the light source to
the power cord from the product in advance. When you replace the lamp
immediately after use of the microscope, wait until the lamp housing and the
lamp are sufficiently cooled down.

Secure the sufficient space around the lamp housing.
The surface of the lamp housing on the back of the microscope gets very hot.
Therefore, when installing the microscope, secure the sufficient space around
the lamp housing, particularly on the top surface. After the microscope is
installed, check that the space below the lamp housing is sufficiently secured.
Do not attach the lamp housing to the mounting hole of the light
source for transmitted light illumination.
Do not attach the halogen lamp housing to the mounting hole of the light
source for transmitted light illumination by mistake. Otherwise, the cover on
the back of the microscope frame gets very hot and you may get burned.
The lifetime of the lamp housing (not lamp) is 8 years or 20,000 illumination
hours, whichever occurs first, as a guideline. For details, see "9 Preventive
inspection sheet for illumination devices" on page 123.
