Abstract: The invention provides an adjustable-installed recessed lighting including a lighting body on which a support hole is arranged; a spring leaf having the top end recessed by the support hole and a bottom end; wherein, a sliding chute located below the support hole is arranged on the lighting body; said support hole has multilevel clamping openings along the direction of the height; the top end of said spring leaf is inserted in the clamping opening and the bottom end may slide in the sliding chute. Since the support hole has multilevel clamping openings, the top end of the spring leaf may be inserted in the clamping opening with different height depending on the thickness of the installation wall; because of the setting of the sliding chutes, the spring leaf can keep the same bend for the different thickness of the installation wall so that the installation of the lighting is facility, simple and fastness.
