An emergency lighting unit comprises a housing which contains the lighting unit circuitry. The housing includes a wall which defines at least one substantially circular opening therein. Extending partially through this opening is a substantially spherical lighting head containing a light source, such as a halogen lamp. The lighting head is rotatable by hand to any desired rotation to vary the field of illumination.
