Two-pack fluorescent tubes for appliance fixtures

The Sylvania T12 F25T12/CW/30 ships as a pair of 25 watt linear tubes built for preheat fixtures that accept a medium bi-pin G13 base. Each lamp measures 30 inches long with a 1.5 inch diameter and delivers a 4100K cool white colour finish suited to task lighting in appliances or utility spaces.

Capacity and headroom in daily use

Rated at 9000 average hours, the tubes provide extended service before replacement is needed. The 25 watt draw and preheat starting method suit existing ballasts designed for T12 operation; they will not strike on instant-start or rapid-start circuits that lack a starter. Light output follows the rated lumen curve for this wattage and length.

Thermals noise and power draw

Normal operation runs at the stated 25 watts with minimal audible hum from the ballast rather than the tubes themselves. Surface temperature stays within typical fluorescent limits for enclosed appliance compartments. No fan or active cooling is involved, so acoustic output is limited to faint ballast vibration in quiet rooms.

Questions about this item

Will the Medium Bi-Pin (G13) base on these 30 inch T12 tubes fit my existing preheat fixture?

Yes, the Medium Bi-Pin (G13) base is the standard interface for T12 preheat fixtures, so these 30 inch tubes will seat directly into your existing sockets.

How can I confirm the 4100K Cool White output is performing correctly after installation?

The tubes should illuminate with a neutral white glow and reach full brightness within seconds; flickering or dim ends after the warm-up period indicates a ballast or starter issue.

Does the 2-pack include starters or just the two 25 watt fluorescent tubes?

The pack contains only the two 30 inch, 1.5 inch diameter T12 tubes; starters and ballasts are separate components required for preheat operation.
