A lantern, intended for wearing on the head against the forehead, has a hollow rectangular body in three portions (7, 1, 2) from front to rear secured together in watertight manner with the interpolation of sealing means (9, 11). The rear portion (2) has a rear wall (3) of part-cylindrical shape and concave so as to fit against the forehead. A parabolic reflector (7) is secured at the front opening of an intermediate portion (1). A lampholder (5) projects forwardly from the concave rear wall (3), and a lamp (13) in the holder (5) projects through a central hole (8) of the reflector (7). Stops (6) for positioning the reflector (7) project forwardly from the concave rear wall (3) and abut the rear face of the reflector (7). The intermediate portion (11) has at each side a fastener (5) for a preferably extensible head band (16) to be passed about the back of the user's head to hold the lantern in position on the head. |
