A niche light 10 includes a receptacle 43 for mounting to the wall of a pool or spa and 5 a housing 25 for mounting to the receptacle 43. The housing 45 defines a sealed compartment for accommodating a light emitting device. The housing 25 is releasably connected to the receptacle 43 by a rotatable connector 40, with the arrangement being such that in a first position of the housing 25 relative to the receptacle 43, the housing 25 can be positioned for connection or disconnection from 10 the receptacle 43, and a second position in which the housing 25 is rotated relative to the receptacle 43 from the first position and in which the housing 25 is connected to the receptacle 43. The rotatable connection further comprises a lock, which includes an abutment head 75 and a projection 76 that includes an abutment surface 78. The lock is enabled when the abutment head 75 engages against the abutment surface 15 78, to prevent the housing 25 being rotated from the second position to the first position. cc) I.'))
