The Keystone SmartDrive 13W T5 LED is a "plug-and-play" solution designed for rapid energy retrofits in fixtures currently using T5HE (High Efficiency) fluorescent lamps. Because it is ballast-dependent, it installs directly into existing fixtures without requiring a ballast bypass or complex rewiring. This minimizes labor expenses and is ideal for quick transitions in large commercial office and classroom spaces.
This 13W LED lamp delivers 1,800 lumens, serving as a direct energy-saving replacement for standard 28W F28T5 fluorescent tubes. By providing equivalent light levels while reducing energy consumption by more than 50%, this bulb helps facilities meet stringent Lighting Power Density (LPD) targets without sacrificing the brightness required for task-oriented environments.
A Color Rendering Index (CRI) of 80+ ensures that the light output accurately represents colors and provides high visual clarity. In educational and professional settings, this level of color accuracy is essential for reducing eye strain during long hours of reading or screen use and ensures that physical instructional materials remain clear and legible.
This 13W T5 LED is available in 3500K (Neutral White), 4000K (Cool White), and 5000K (Daylight). The 4000K and 5000K options are the industry standard for productivity-focused zones like laboratories and open offices, while the 3500K option provides a slightly warmer tone preferred for lobbies or breakrooms where a more relaxed atmosphere is desired.
The lamp is constructed with a shatterproof coating over a glass housing. This hybrid design offers the superior heat dissipation and rigidity of glass while providing the safety of polycarbonate. If the lamp is struck, the coating contains any glass shards, making it compliant with ETL and NSF standards for use in food prep areas, hospitals, and high-traffic schools.
SmartDrive technology is designed to work seamlessly with the existing electronic ballasts found in many T5HE fixtures. This allows the LED tube to operate using the existing electrical infrastructure safely. It is critical to confirm ballast compatibility before installation to ensure the long-term reliability of the system and to maintain the fixture’s UL and DLC certifications.
Rated for an operational life of 50,000 hours, this T5 LED significantly outlasts traditional fluorescent technology, drastically reducing maintenance and replacement cycles. Keystone Technologies backs this product with a 5-year warranty, covering the internal light engine and ensuring a reliable return on investment for commercial facility upgrades.
