Replacement for Halco CFL18/41/T2 - 18W, Cool White, Spiral

A spiral-style replacement for the Halco CFL18/41/T2, this 18-watt CFL generates substantial light output from its twisted tube geometry. Features an E26 medium base for easy installation.

Light output of 1100 lumens works well for task lighting and smaller spaces. The 4100K cool white color temperature produces light that feels clean and professional - crisp and clean with a slight blue undertone. At 85 CRI, colors appear more natural and accurate than with standard-grade lamps.
