Sylvania 22509 15W T8 Daylight Tubes

This pack contains six Sylvania 22509 fluorescent tubes, each 18 inches long with a medium bi-pin G13 base. They operate at 15 watts and produce a 6500K daylight colour temperature. The T8 form factor suits compatible fixtures in workshops, garages or utility areas. Made in the USA, they are supplied as a convenient six-pack for multiple replacements.

Ideal for multi-lamp fixtures needing 6500K output

These tubes suit owners of T8 fixtures that accept 18-inch, 15-watt lamps with a G13 base and want a cool daylight appearance. They are not for fixtures requiring a different length, wattage, colour temperature or pin spacing. Buyers needing dimmable operation, instant-start electronic ballast compatibility or LED retrofit solutions should look at other product types.

G13 medium bi-pin base determines fit

The single specification that decides compatibility is the medium bi-pin G13 base combined with the 18-inch length and 15-watt rating. Only fixtures designed for this exact lamp designation will accept the tubes and operate them correctly. Verify the fixture label matches F15/T8/D before purchase.

Questions about this item

What does the Medium Bi-Pin G13 base mean for fixture compatibility?

The Medium Bi-Pin (G13) base fits standard T8 fluorescent fixtures with matching sockets; verify your fixture accepts T8 lamps before installing.

What physical space is needed to mount these 18 inch tubes?

Each tube measures 18 inches end-to-end; ensure the fixture channel or troffer provides at least that length plus clearance for the bi-pin sockets.

How are these 15 watt fluorescent tubes installed, and what step is often missed?

Turn off power, align both G13 pins with the socket slots, insert and rotate until seated; the step often missed is confirming both ends lock firmly so the lamp strikes reliably.
