GE F32T8 25W SPX 35 EC fluorescent tubes

This case contains 36 GE 72129 fluorescent tubes rated at 32 watts each. They use a T8 form factor with a medium bi-pin G13 base and measure 48 inches in length. The lamps produce a 3500K colour temperature with a colour rendering index of 85.

50000-hour rated life at 25 watts

The energy-saving design operates at 25 watts while delivering the light output of a standard 32-watt T8 tube. This reduced power draw extends the rated life to 50000 hours, lowering replacement frequency and ongoing energy costs for continuous-use installations.

Suited for commercial retrofits needing lower

Facilities managers upgrading existing T8 fixtures to cut electricity use will match the G13 base and 48-inch length directly. Buyers who require a different colour temperature, higher lumen output, or instant-start ballast compatibility without a 25-watt energy-saving label should look at alternative lamp specifications.

Questions about this item

What light output does the 3500 K colour temperature give in a real fitting?

The 3500 K rating produces a neutral white light that sits between warm and cool tones, suitable for general commercial and office spaces.

How does the G13 medium bi-pin base limit the ballasts I can use?

The G13 base fits standard T8 electronic or magnetic ballasts wired for 48-inch lamps; it will not work with T5 or single-pin sockets.

What fixture length and mounting does the 48-inch tube need?

The lamp requires a 48-inch linear fixture with G13 lampholders spaced for a T8 diameter tube.
