Case of 15 U-bend fluorescent tubes

This case contains fifteen Sylvania 21726-1 FB016/865/XP fluorescent tubes. Each tube draws 16 watts and delivers 1125 lumens at a 6500K colour temperature. The lamps use a medium bi-pin G13 base and measure 10.5 inches in a U-bend T8 form factor. They are sold new in a single 15-piece package.

Suited for G13 U-bend fixtures needing cool white

These lamps fit fixtures that accept a T8 U-bend tube with a G13 base and a 10.5-inch leg spacing. Buyers who need a different colour temperature, a straight tube, or a different pin spacing should look at other options. The 15-piece case quantity may also exceed the needs of a single-fixture replacement.

G13 base and 10.5-inch U-bend T8 geometry

The decisive specification is the combination of a medium bi-pin G13 base with a 10.5-inch U-bend T8 tube shape. Only fixtures designed for this exact base and physical layout will accept these lamps. Verify the fixture requirements before ordering.

Questions about this item

How much heat does a 16 W U-bend tube add to a ceiling fixture running all day?

At 16 watts each, the 15 tubes convert most input power into light rather than heat, so a standard commercial fixture stays only slightly above ambient temperature during continuous operation.

What fixture and ballast are required for the G13 base and 16 W rating?

You need a T8 U-bend fixture with a medium bi-pin (G13) socket and an electronic ballast rated for 16 W FBO16/865/XP lamps; the 10.5-inch leg spacing must match the fixture.

Will the 6500 K output match the colour of older 6500 K T8 tubes I keep in the same room?

Yes, the 6500 K colour temperature is identical, so the 1125-lumen Octron Curvalume tubes will blend with existing 6500 K straight T8s without a visible shift.
