Fluorescent lamp 4-pack for general lighting

This pack contains four Sylvania F15T12/DSW/RP fluorescent tubes rated at 15 watts each. Each 18-inch tube delivers 770 lumens at a 3000K colour temperature. The medium bipin base fits standard T12 fixtures. They suit offices, workshops and retail spaces needing consistent warm-white light.

Steady output over long operating periods

The 15-watt design maintains stable lumen output during extended use without the intensity drop seen in short-cycle operation. Phosphor coating sustains the 3000K tone across the rated life. Warm-white colour remains consistent from start-up through continuous daily running.

Medium bipin bases simplify replacement

T12 glass construction with medium bipin ends allows direct insertion into existing sockets. The 18-inch length matches common fixture spacing in commercial ceilings. Four tubes per case support planned maintenance schedules for multi-lamp installations.

Questions about this item

How much heat does one 15‑watt T12 tube add to a room when it runs all day?

Each tube consumes 15 watts, so nearly all of that power becomes heat; a single lamp adds the same warmth as a 15‑watt heater running continuously.

What fixture or ballast do I need to run these F15T12/DSW/RP lamps?

They require a compatible T12 fluorescent fixture with a medium bipin socket and a ballast rated for 15‑watt, 18‑inch T12 tubes.

Will these 18‑inch, 3000K tubes work in an older magnetic‑ballast shop light?

Yes — they are standard 18‑inch T12 tubes with medium bipin bases, so they fit legacy magnetic‑ballast fixtures designed for F15T12 lamps.
