Product Overview
DULUX® F lamps are pin-based compact fluorescents. The 4-pin lamps have no internal starter; starting is a function of the ballast. They are designed for electronic ballast operation and are dimmable per the manufacturer catalog. This lamp is not a self-ballasted screw-in CFL.
DULUX F lamps can typically be operated on DULUX L and PENTRON HO ballasts of the same or similar wattage; check with the ballast manufacturer to verify lamp and ballast compatibility.
