wherein said adaptor is rotationally movable with respect to said base when said adaptor is engaged with said connecting assembly, wherein said adaptor assembly can be mounted in locations too restricted for rotation of said irregularly shaped housing by engaging said connecting assembly with an internally threaded electrical socket, and engaging said second and third connectors and rotating said irregularly shaped housing to a desired orientation. ### Claim 2 (depends on 1) The adaptor assembly as defined in claim 1 wherein said third connector is axially engageable with said first connector of said connecting assembly. ### Claim 3 (depends on 1) The adaptor assembly as defined in claim 1 wherein said base of said connecting assembly includes a threaded male screw-in element for engaging the threads of the incandescent lamp socket. ### Claim 4 (depends on 1) The adaptor assembly as defined in claim 1 wherein said top of said connecting assembly includes a nonconductive platform. ### Claim 5 (depends on 1) The adaptor assembly as defined in claim 1 wherein at least one of said first and said third connectors includes a retaining member for positively locking said connecting assembly and said adaptor together. ### Claim 6 (depends on 5) The adaptor assembly as defined in claim 5 wherein said retaining member is hook-like in shape. ### Claim 7 (depends on 5) The adaptor assembly as defined in claim 5 further including a tool member for unlocking said retaining member to enable said connecting assembly and said adaptor to be separated. ### Claim 8 A lamp adaptor assembly for adapting an internally threaded electrical socket for use with a lamp, comprising: a connecting assembly having a top and a base, said base configured for inserting within and engaging a threaded electrical socket; an adaptor having a housing, a first connector for receiving a lamp and a second connector for engaging said top of said connecting assembly; wherein at least one of said top and said second connector includes a retaining member for positively locking said connecting assembly and said adaptor together; and a tool member for unlocking said retaining member to enable said connecting assembly and said adaptor to be separated; wherein said housing has a top face having a first aperture and said second connector has an internal wall having a second aperture, and wherein said tool member is inserted through said first aperture and said second aperture to unlock said retaining member. ### Claim 9 (depends on 8) The adaptor assembly as defined in claim 8 wherein said retaining member includes a ramp for guiding said tool member. ### Claim 10 A lamp adaptor assembly for adapting an internally threaded electrical socket for use with a lamp, comprising: a connecting assembly having a top and a base, said base configured for inserting within and engaging a threaded electrical socket; an adaptor having a housing, a first connector for receiving a lamp and a second connector for engaging said top of said connecting assembly; wherein at least one of said top and said second connector includes a retaining member for positively locking said connecting assembly and said adaptor together; and a tool member for unlocking said retaining member to enable said connecting assembly and said adaptor to be separated; wherein said base of said connecting assembly includes a wall portion having an outer surface and a threaded male screw-in element for engaging the threads of the incandescent lamp socket, wherein said element is held in surrounding relationship relative to said outer surface of said wall portion, and wherein said element is freely rotatable relative to said outer surface unless said tool member is inserted therebetween to engage said element and said wall portion together. ### Claim 11 (depends on 10) The adaptor assembly as defined in claim 10 wherein said top of said connecting assembly has an opening through which said tool member inserts to engage said element and said wall portion together. ### Claim 12 A lamp adaptor assembly for adapting an internally threaded electrical socket for use with a lamp, comprising: a connecting assembly having a top and a base, said base configured for inserting within and engaging a threaded electrical socket; an adaptor having a housing, a first connector for receiving a lamp and a second connector for engaging said top of said connecting assembly; and a tool member, wherein said base of said connecting assembly includes a wall portion having an outer surface and a threaded male screw-in element for engaging the threads of the incandescent lamp socket, wherein said element is held in surrounding relationship relative to said outer surface of said wall portion, and wherein said element is freely rotatable relative to said outer surface unless said tool member is inserted therebetween to engage said element and said wall portion together. ### Claim 13 (depends on 12) The adaptor assembly as defined in claim 12 wherein said top of said connecting assembly has an opening through which said tool member inserts to engage said element and said wall portion together. ### Claim 14 A lamp adaptor assembly for adapting an internally threaded electrical socket for use with a lamp, comprising: a connecting assembly having a top and a base, said base including a threaded male screw-in element for inserting within, and engaging the threads of, a threaded electrical socket, said top including a nonconductive platform; an adaptor having a housing, a first connector for receiving a lamp, and a second connector for axially engaging said top of said connecting assembly; wherein at least one of said top and said second connector includes a retaining member for positively locking said connecting assembly and said adaptor together; and a tool member for unlocking said retaining member to enable said connecting assembly and said adaptor to be separated; wherein said base of said connecting assembly includes a wall portion having an outer surface, wherein said threaded male screw-in element is held in surrounding relationship relative to said outer surface, and wherein said element is freely rotatable relative to said outer surface unless said tool member is inserted therebetween to engage said element and said wall portion together. ### Claim 15 (depends on 14) The adaptor assembly as defined in claim 14 wherein said top of said connecting assembly has an opening through which said tool member inserts to engage said element and said wall portion together. ### Claim 16 A lamp adaptor assembly for adapting an internally threaded electrical socket for use with a lamp, comprising: a connecting assembly having a top and a base, said base including a threaded male screw-in element for inserting within and engaging the threads of a threaded electrical socket, said top including a nonconductive platform and a retaining member; an adaptor having a housing, a first connector for receiving a lamp, and a second connector for axially engaging said top of said connecting assembly; and a tool member; wherein said retaining member positively locks said connecting assembly and said adaptor together when said second connector and said top are axially engaged, and wherein said connecting assembly and said adaptor remain locked together until said retaining member is unlocked by engagement with said tool member; wherein said base of said connecting assembly includes a wall portion having an outer surface, wherein said threaded male screw-in element is held in surrounding relationship relative to said outer surface, and wherein said element is freely rotatable relative to said outer surface unless said tool member is inserted therebetween to engage said element and said wall portion together. ### Claim 17 (depends on 16) The adaptor assembly as defined in claim 16 wherein said top of said connecting assembly has an opening through which said tool member inserts to engage said element and said wall portion together. ### Claim 18 A fluorescent adaptor assembly for adapting an internally threaded incandescent lamp socket for use with a fluorescent bulb, comprising: a connecting assembly having a top and a base, said top including a nonconductive platform and a retaining member, said base including a wall portion having an outer surface and a threaded male screw-in element for engaging the threads of an incandescent lamp socket, said element held in surrounding relationship relative to said outer surface;
