This package includes the Aqua Ultraviolet Advantage 2000 UV Sterilizer 8W Lamp, Quartz Sleeve, & Silicone Lube. The Silicone Lube is for all o-rings on your Aqua Ultraviolet UV Sterilizer. O-rings and gaskets, including the quartz sleeve gasket, should be lubricated annually, and when you're changing out your bulb and quartz sleeve is the perfect time to do this.

The Aqua Ultraviolet Advantage UV Sterilizer 8 Watt Replacement Lamp is 8.5" long (including pins). This Lamp WILL NOT work with the Aqua Ultraviolet Classic UV Sterilizer.

The replacement Aqua Ultraviolet Advantage 2000 8 Watt Quartz Sleeve is 11.5" long and includes the rubber gasket.
