Panasonic's WhisperValue and WhisperValue-Lite are Energy Star ventilation fans with a 3 3/8-inch housing depth for a 2-inch by 4-inch joist cavity or stud wall. They use an L-shaped bracket, are UL approved and include a Universal-Can Contractor Pack to allow initial fan housing and delayed motor installation. The WhisperValue series has 50-, 80- or 100-cubic-feet per minute airflow circulation. Some models feature two 13-watt, self-ballasted GU24 base CFL lamps and a 4-watt night-light.
