Replacement for GE F21T5/841/WM/ECO - 21W, Cool White, Linear T5, Bipin Base

This 21-watt energy-saving linear fluorescent tube replaces the GE F21T5/841/WM/ECO. Designed as a direct retrofit for higher-wattage lamps, it delivers comparable light output while reducing energy consumption - a simple way to cut lighting costs without replacing fixtures or ballasts. The lamp features a G5 miniature bi-pin base, standard for T5 linear tubes.

At 1974 lumens, light output is solid - appropriate for general ambient lighting and task areas. The 4100K cool white color temperature produces light that feels bright and productive - crisp and clean with a slight blue undertone. This makes it well-suited for offices, schools, hospitals, retail stores, and industrial facilities. At 82 CRI, color rendering meets the standard for most commercial and residential applications, with colors appearing natural and accurate.
