[0032] A lighting apparatus 6 for also outdoor operation, comprises an ancillary fixing device, i.e., an end cap equipped with a counter thread which in turn can be screwed to the threaded terminal already present in the light bulb. This cap is further equipped with a buffer battery, which can be recharged separately and is useful for prolonged operation in supplying electrical energy in “outdoor” use, the eyelet located at the end serving as a through loop to hang in suspension the light bulb with a simple cable/loop, as can also be seen in FIG. 3.

[0033] A passive energy recovery system during normal operation of the lighting apparatus and consequent energy saving thanks to the partial and consequent self-charging exploited for domestic lighting, as well as for self-charging in am IOT perspective, the batteries are integrated in the threaded terminal as can be seen.
