A retention system for holding a light source lamp in a recessed luminaire includes a retention spring portion that is pivotally coupled to a light source holding bracket of the recessed luminaire. The light source holding bracket is configured to house a light source lamp therein. Further, the retention system includes a retention arm portion that extends from and is formed integral with the retention spring portion. The retention spring portion forces the retention arm portion towards the light source holding bracket such that the retention arm portion engages and applies an active load on the light source lamp that is disposed in the light source holding bracket to securely retain the light source lamp within the recessed luminaire.
