Philips 18 inch T12 Fluorescent Tube (F20T12/CW/ALTO (273326)) is the 20W / 4100K version. In a troffer or strip fixture with sockets for T12 lamps, this model can be considered for the matching lamp position. A fixture with integral LED boards requires a different replacement approach. Where the break room or work area is specified at 4100K, this version keeps the replacement within the same colour family. This model is sold here as a 30-unit pack.
For the 24-inch T12 installation, select the circuit for this 20W lamp rather than using length as the only compatibility check. Match the G13 base as well as the lamp length when retaining the fixture. Keep this model on a fluorescent lamp circuit with the corresponding ballast lamp rating and operating configuration.
Buying tip: Match the lamp designation and pin arrangement to the existing ballast. Measure the installed lamp before ordering a different length.
