Protection class III
Lights for use with protection low voltage.
Three classes protection are also defined for lights;
these set out the scope protective provisions against
electric shocks:
Protection class I

General information
Safety zones for the use lights the
bathroom
Bathrooms are damp rooms, and special care must be
taken wherever electricity and damp come together. Three so-called safety areas for bathrooms are
set out the standard DIN VDE (Germany Industrial
Standard, Association German Electrotechnicians) 0100
Section 701. The lower limit the floor; the area
stretches 2. The
following regulations have been drawn the interests
of safety. Protection low voltage means that higher
voltage circuits supply low voltage circuit; the two must
be securely separated. Any lights
used areas and must have protection rating of
at least X4; for devices which spray jets water, for
example massage jets, lights must have protection rating
of least X5.
