The Keystone 11W Dual Mode 3ft T8 LED is a "ComboDrive" solution designed for maximum installation versatility. It can operate as a plug-and-play lamp (Type A) utilizing the existing compatible ballast, or as a ballast bypass lamp (Type B) connected directly to 120–277V line voltage. This flexibility allows for immediate energy savings with the ballast in place, while providing a path for future Engineering Resilience by bypassing the ballast if it fails.
This 11W lamp delivers 1,700 lumens, serving as a high-efficiency replacement for standard 25W–30W F30T8 fluorescent tubes. By producing equivalent light levels with significantly lower energy consumption, it helps commercial facilities reduce their Lighting Power Density (LPD) and comply with 2026 Code Enforcement mandates for energy efficiency in office and classroom environments.
A Color Rendering Index (CRI) of 80+ ensures that the light output accurately represents colors and provides high visual clarity. This is essential for maintaining productivity in workspaces, reducing eye strain for occupants, and ensuring that instructional materials or architectural features are viewed with high-definition clarity.
This 11W T8 LED is available in 3500K (Neutral White), 4000K (Cool White), and 5000K (Daylight). The 4000K and 5000K options are the industry standard for enhancing focus and alertness in office settings, while the 3500K option provides a warmer, more balanced tone suitable for hospitality or hallway lighting.
The lamp is constructed with a shatterproof coating over a glass housing. This hybrid design provides the superior thermal management and structural rigidity of glass—ensuring the tube will not sag or yellow over time—while offering the safety of polycarbonate. If the lamp is struck, the coating contains the glass shards, making it suitable for food service areas, healthcare facilities, and educational zones.
The G13 Medium Bi-Pin base is the universal standard for T8 fixtures, ensuring a secure fit into existing lampholders. At 35.78 inches in length, this lamp is specifically designed for 3-foot troffers and vanity fixtures. Because it is a Dual Mode lamp, it is compatible with both shunted and non-shunted tombstones depending on the wiring configuration used during installation.
Rated for 50,000 hours of operational life, this T8 LED drastically reduces the cost and frequency of maintenance cycles compared to traditional fluorescent tubes. Keystone Technologies backs this product with a 5-year warranty, covering the internal driver and light engine, ensuring a reliable return on investment for commercial infrastructure upgrades.
