Replacement for Sylvania FP21/835/ECO - 21W, Linear T5, Bipin Base

This 21-watt T5 linear fluorescent tube replaces the Sylvania FP21/835/ECO. Featuring a G5 miniature bi-pin base (standard for T5 linear tubes), it provides reliable illumination for commercial, retail, and residential applications.

At 1974 lumens, light output is solid - appropriate for general ambient lighting and task areas. The 3500K neutral white color temperature produces light that feels balanced and versatile - neither warm nor cool, striking a middle ground. This makes it well-suited for offices, kitchens, bathrooms, and mixed-use commercial spaces. At 82 CRI, color rendering meets the standard for most commercial and residential applications, with colors appearing natural and accurate.
