The Keystone SmartDrive T5 LED is a "plug-and-play" solution designed for rapid energy retrofits. Because it is ballast-dependent, it installs directly into existing fluorescent fixtures without the need for complex rewiring or bypassing the ballast. This significantly reduces labor costs and downtime, making it an ideal choice for large-scale upgrades in office corridors and educational facilities.
This 25.5W LED lamp delivers up to 3,300 lumens, providing a high-intensity light output that effectively replaces standard 54W F54T5/HO fluorescent tubes. By producing equivalent brightness while consuming less than half the power, this bulb helps facilities meet strict energy standards for Lighting Power Density (LPD) in commercial office and classroom environments.
With a Color Rendering Index (CRI) of 80+, this T5 LED ensures that colors appear vibrant and accurate. In classrooms and offices, high CRI is essential for reducing eye strain during long reading sessions and ensuring that instructional materials and digital screens are viewed with maximum clarity. This supports a more productive environment by improving visual comfort.
This model is available in 3500K (Neutral White), 4000K (Cool White), and 5000K (Daylight). The 4000K and 5000K options are frequently utilized in professional infrastructure projects to boost alertness and concentration, while 3500K offers a softer tone suitable for executive offices or common areas where a more inviting atmosphere is desired.
The lamp features a shatterproof coating over a glass housing, combining the superior thermal management of glass with the safety of polycarbonate. This design prevents glass shards from escaping in the event of breakage, meeting ETL Sanitation and NSF requirements for use in food service areas, laboratories, and high-traffic educational zones.
Keystone’s SmartDrive technology is engineered for broad compatibility with most program-start electronic T5HO ballasts. This allows the LED tube to utilize the existing fixture's infrastructure safely. It is important to verify ballast compatibility prior to installation to ensure system reliability and to maintain the fixture's UL and DLC listings.
Rated for 50,000 hours of operational life, this T5 LED lasts significantly longer than traditional fluorescent tubes. It is backed by a 5-year warranty from Keystone Technologies, covering the light engine and integrated circuitry. This long-term reliability minimizes maintenance cycles and provides a stable ROI for commercial property managers.
