The lighting device includes a barrel (10), a lamp (14) mounted on one end of the barrel, a tubular coupler (20) secured around one end of the barrel, a tubular sleeve (30) made of a light transmittable material and sleeved slidably on the coupler, and a head cap (40) secured to one end of the sleeve and contg. a reflector (41). The sleeve is shiftable w.r.t. the coupler between a first position, where the lamp extends into the reflector so that light is directed axially, and a second position, where the lamp is located in the sleeve such that light passes transversely through the sleeve. |
