Replacement Fluorescent Lamp, 21W, T5, G5, 2PK

The GE F21W/T5/841/ECO is a high-efficiency linear fluorescent lamp engineered for demanding commercial and industrial applications. This 21-watt T5 lamp delivers exceptional performance with 2,100 initial lumens and a mean output of 1,930 lumens, making it ideal for task lighting, office environments, retail spaces, and industrial facilities where consistent, reliable illumination is essential. Featuring GE's StarCoat Ecolux technology, this lamp combines superior light quality with energy-efficient operation. The 4100K cool white color temperature (designated as 841) provides a neutral, daylight-like appearance that promotes alertness and visibility, making it particularly suitable for workstations, manufacturing areas, and detailed task environments. With an 85 color rendering index, colors appear natural and accurate under this lamp's light. The F21W/T5/841/ECO utilizes a double-end G5 miniature bipin base, enabling straightforward installation in standard T5 compatible fixtures. The linear design measures 33.4 inches in overall length and integrates seamlessly into existing lighting systems without requiring ballast modifications. This lamp is compatible with standard electronic ballasts commonly found in modern commercial lighting infrastructure. Rated for exceptional longevity, this fluorescent lamp delivers 30,000 hours of service life under standard 3-hour start cycles and extends to 36,000 hours under 12-hour start cycle operation. This extended lifespan reduces replacement frequency and associated labor costs, contributing to lower total cost of ownership over the lamp's service life. The eco-conscious ecolux formulation reduces energy consumption while maintaining superior light output and color consistency. This makes the lamp an environmentally responsible choice for facilities seeking to balance operational efficiency with sustainability goals. The F21W/T5/841/ECO is ideal for retrofit projects and new installations where energy savings and performance reliability are priorities.
