13 watt T5 fluorescent tube for warm white lighting

This 13 watt T5 tube produces a 3000K warm white glow from a 21 inch straight glass envelope. It fits a miniature bi-pin G5 base and operates on a preheat ballast. The lamp suits under-cabinet fixtures, display cases and similar slim-profile fittings.

Replaces older T5 tubes of the same wattage

The upgrade is worthwhile when an existing 13 watt T5 has dimmed, flickers or shows end-darkening. It is not for fixtures that require instant-start or rapid-start ballasts, for high-output T5 sockets, or for any fitting that demands a different pin spacing or tube diameter.

Questions about this item

Will the 21-inch length and G5 bi-pin base fit my existing T5 fixture?

This tube measures 21 inches end-to-end and uses the standard G5 miniature bi-pin base, so it matches any fixture designed for F13T5 lamps.

Do I need a starter or ballast change when installing this preheat fluorescent tube?

It operates on a preheat ballast with a separate starter; the common mistake is fitting it to an instant-start or electronic ballast without the required starter.
