This recessed can light trim is designed for standard recessed cans including Halo, Juno and ceiling light fixtures, it also works with PAR30, PAR38, BR30, BR40, and similar-sized halogen, incandescent, or LED bulbs. The step baffle design softens the light and brings a non-glaring light. With the integrated iron ring, this trim makes your room aesthetically attractive, covering the gap or breach caused by over-cutting.
