FAQ

"T5" refers to the tube's diameter. The "T" stands for tubular, and the "5" means it has a diameter of 5/8ths of an inch (approximately 16 mm). This makes it a slim and energy-efficient lamp compared to older T8 or T12 models.

T5 fluorescent lamps like the F8W/T5/33-640 are designed to operate exclusively with electronic ballasts. They will not work correctly or may be damaged if connected to an older magnetic ballast intended for T8 or T12 lamps.

This is an older Sylvania color designation. The "33" and the name "Cool White" indicate a color temperature of approximately 4000K, which is a neutral white light. The "640" part relates to the Color Rendering Index (CRI), which is in the range of 60-69 for this lamp, suitable for general-purpose lighting where precise color accuracy is not critical.
