Our QuietBox is sized to fit many different models of recessed light housings from various manufacturers including housings that use LED, incandescent, low voltage, and CFL bulbs. We only approve use of IC rated housings within our QuietBox. Non-IC rated housings are prohibited from being installed inside our QuietBox. Non-IC rated housings will generate a significant amount of heat which will in turn cause the bulb to either overheat and shut off or possibly spark a fire. DO NOT use a non-IC rated recessed light housing inside the QuietBox. If you do not know if your housing is IC rated or non-IC rated then contact the manufacturer or replace the housing entirely with an IC rated housing.
Seriously, NO non-IC rated housings allowed.
