The present disclosure sets forth an outdoor security light with the flexibility of being mounted to either a wall structure or to an eave or ceiling structure. The security light can be adjusted for each installation without the necessity of changing hardware elements of the security luminaire. Disclosed designs include a luminaire housing having a housing mount which is removably received within a housing mount attached to a structure. The mechanical and electrical interface between the two may allow a removable engagement with a lock mechanism for an easy installation, while providing electrical power to the luminaire housing and communication therebetween.
