Product Description
Product Details
Product Construction
A phosphor-coated glass tube is bent into a ring and joined to a central bridge that holds the four electrical pins. During operation, discharge inside the tube excites the coating to produce visible light around the circular envelope.
Selection & Installation Notes
Match the lamp power and output range to a suitable electronic ballast, then verify ring clearance and GR10Q holder orientation. The fixture, holder and ballast are separate from the replacement lamp. Compare related formats in our circular and 2D fluorescent lamp range.
