Air stratification within lamp compartments can produce highly constricted thermal environments in many compact fluorescent recessed downlights. Because compact fluorescent lamps are highly sensitive to ambient temperature, a constructed thermal environment can reduce the lamp's light output. Passive ventilation through the lamp compartment into the surrounding plenum can reduce thermal stratification within the fixture housing, resulting in cooler lamp temperatures and a corresponding increase in light output of 15 percent to 20 percent. Passive ventilation can be achieved by using appropriately located venting apertures that promote a convective flow through the compartment.
