Sylvania 15W T8 Daylight Tube

The Sylvania 22509 is an 18 inch fluorescent tube with a medium bi-pin G13 base. It draws 15 watts and produces 6500K daylight output. This lamp suits fixtures that accept T8 tubes in workshops, garages or utility areas. It is manufactured in the USA.

Sustained output on standard ballast

When powered by a compatible ballast the tube reaches full brightness after a brief warm-up. Light level remains stable over long operating periods without the sharp decay seen in some discharge sources. The 15 watt rating reflects continuous power draw rather than a peak figure. Colour consistency holds across the rated life.

Cool operation with minimal noise

Fluorescent technology runs cooler than incandescent equivalents at the same lumen output. The tube itself generates modest heat that dissipates along its 18 inch length. Audible hum is limited to the ballast, not the lamp. Power draw stays at the stated 15 watts during normal use.

Questions about this item

How much heat does a 15 watt T8 tube add to a small enclosed fixture running all day?

At 15 watts the tube produces modest warmth; ensure the fixture has ventilation slots so heat can escape during continuous operation.

What fixture or ballast must I already have for this Medium Bi-Pin G13 base tube?

You need a compatible T8 fixture with a G13 lampholder and an electronic or magnetic ballast rated for 15 watt F15/T8 lamps.

Will this 6500K daylight tube work in an older magnetic-ballast shop light I already own?

Yes, the F15/T8/D tube fits legacy magnetic ballasts designed for 15 watt T8 lamps, though flicker may be more noticeable than with electronic ballasts.
