Abstract: A twist-and-lock mounting bracket may secure a lighting fixture to a mounting surface. The twist-and-lock mounting bracket may define an aperture having features corresponding to the shape of a twist-and-lock element disposed on a housing of a lighting fixture. Accordingly, the twist-and-lock element may be configured to extend through the aperture while the corresponding features of the twist-and-lock element and the aperture are aligned. The housing may then be rotated such that the tabs do not align with the corresponding features of the aperture, and the twist-and-lock element is thereby prevented from sliding through the aperture. The mounting bracket may be secured to a junction box positioned within a mounting surface, or it may be secured to a biasing bracket having one or more second resilient members configured to engage the interior of a recessed can light, such that the lighting fixture may be secured to the recessed can light.
