Abstract
Lamp for photographic laboratory, characterized essentially by the fact of being constituted by two monopieza molded bodies, one of which integrates a cylindrical resolution base that incorporates the bulb holder for a conventional bulb, while the other body integrates a screen of translucent material colored, in the form of an inverted cup, threaded in its embouchure for its connection to the base body through a thread provided in the inner wall thereof; and in that said base body has a raised base with respect to the support plane with aeration orifices obturable by an auxiliary disk of porous material that prevents the exit of light by orifice discs.
