Improved adjustable luminaire, characterized in that on a base plate, a ball joint is screwed in a support part with a hemispherical inner surface end, which relates to another symmetrical through an inner bushing on which both threaded, being arranged between both some washers with a warped surface and a spring that urges them against the ball joints to position them, the ball joint of the second piece being related to the lateral surface of a cylindrical tulip with a bevelled base, carrying the other base that is partially open, fixed a bulb holder all in such a way that the ball joints determine a double articulation to position the tulip as desired, allowing to be hollow the ball joints and the parts that embrace them, the hidden passage of the cable that connects the lamp holder with the electrical installation.
