Keep in mind
Depending on the Germicidal UV Light model there will either be a single O-ring on one side of the quartz sleeve, or two o-ring seals on either side of the quartz sleeve.
Germicidal UV light models that are sealed on one side will only use a single o-ring, such as the E-60 or HC-720 UV Lights.
Germicidal UV light models that have two caps on either side of the housing will require two o-rings, such as the E-180 or EB-24 UV Lights.
