Sylvania 9-inch Circular Fluorescent Tube - 22W | 4100K | 2G10 | 4 Pin | Pack of 12

[27663] is the Sylvania 9 inch Circular Fluorescent Tube in the 22W, 4100K configuration. Select this model for a compatible fixture using this shaped-tube format, with the lamp holders positioned for the same geometry. This 4100K version is useful for keeping a consistent colour across the shared interior during a replacement project. The sales unit for this model is a pack of 12. Its 2G10 contacts determine the required lampholder interface. The ballast and socket arrangement must support this model as a fluorescent lamp; matching the physical length alone is insufficient for ballast selection.

Buying tip: Check the existing socket for the 2G10 base and compare the available clearance with the lamp dimensions.
