  • Soft white glow from 2700 K colour temperature

  • 10 000-hour average life reduces replacement frequency
  • 13 W power draw keeps energy use low
  • CRI 82 renders colours naturally indoors

Compact Fluorescent for Recessed Fixtures

This 13 W double-tube lamp fits GX23-2 bipin sockets found in recessed cans and desk lamps. It produces 780 initial lumens at a warm 2700 K colour temperature with a CRI of 82. The tubular T4 envelope measures 4.6 in length and 1-1/4 in diameter.

ECO Construction and Bipin Mount

The ECO designation indicates reduced mercury content compared to standard compact fluorescents. A GX23-2 two-pin base locks securely into compatible ballasted holders, preventing accidental loosening from vibration. No external starter or separate ballast is required when the fixture already supplies the correct gear.

10000-Hour Rated Life Decides Suitability

Rated at 10000 average hours, the lamp delivers 671 mean lumens over its service span. Buyers needing longer maintenance intervals or higher efficacy should consider alternative technologies not covered by this specification.

Questions about this item

Does the GX23-2 base accept both pins in a single orientation?

Yes, the GX23-2 bipin base has two pins spaced for one-way insertion, so the lamp seats correctly in compatible recessed or desk-lamp sockets.

What are the exact length and diameter so I can check my fixture clearance?

The tubular T4 envelope measures 4.6 inches long and 1-1/4 inches in diameter, fitting most standard recessed cans and desk-lamp housings.

Is there a specific way to seat the lamp so it starts reliably?

Align the two pins with the socket slots, push straight in until the base bottoms out, then give a slight clockwise twist to lock; skipping the twist often leaves the lamp loose and flickering.
