Honeywell UV100E2009 SmartLamp twin 36 watt bulb system. Has an air flow sensor that only powers the bulb when air flow is present, saving bulb life and energy. Designed to treat air flowing in the return duct.
The UV100E2009 is a complete system that includes the base unit with a 120v cord and plug. Two 36 watt bulbs and knobs are included. Three sheet metal screws are included for mounting the unit in the duct.
The Honeywell UV100E2009 utilizes two 36 watt Philips Hot Cathode Germicidal Sterilamp™ Tube. Bulb life expectancy is 8000 hours.
SmartLamp units without an air flow sensor will cycle on and off to extend bulb life (when not controlled by an Enviracom thermostat or other devices). They will run for three hours and then turn off for three hours.
SmartLamp units with the air flow sensor turn on the lamp when air flow is present and will turn off the lamp 40 minutes after air flow has stopped. Turning off the lamp extends bulb life as well as reduces energy usage.
