Abstract: The present invention provides a non-copper base lamp and its holder, in which the lamp is composed of the glass bulb and plastic base combined together matching on holder by locking a dowel pin set on the bottom end of said plastic base on a socket of said holder, instead of the conventional coppered threaded base screwing on the threaded socket of the conventional holder. For preventing the bulb from turning relatively to the plastic base to occur short circuit happening on the heater leads, the lamp has a locking device set upon the bottom side of the bulb and the top side of said base by embedding together tightly for avoiding them relatively turning. On the other side, every pin hole is pre-set two conducting strip slots exactly above the two power cords individually, so that the user can set it in serial or parallel connection by any will.
