The Halo H5 series is designed to accommodate smaller sized PAR20 and PAR30 halogen lamps. The wide variety of trims available allows a number of different lighting effects to be created with one basic housing. The H5 trim size makes the H5RICAT the right choice for applications where dramatic yet inconspicuous lighting is required in an existing ceiling. This is an Air-Tite housing and may be used to meet restricted airflow requirements.
