Keystone's SmartDrive LED series of direct replacement LED T5 tube lights, to replace F54T5HO fluorescent tubes, operates in conjunction with your existing program start fluorescent ballasts. LED T5 tubes provide up to 40 percent energy savings over existing fluorescent lamps, a 50,000 hour rated life. You can now utilize Keystones superior LED technology when replacing T5 fluorescent tubes operating on program start electronic fluorescent ballasts. There is no rewiring of the fixture or hassle of switching out an entire existing fixture body just power off, remove the old technology and replace with Keystone SmartDrive T5 LED tubes to take advantage of energy and maintenance savings.

This series of Keystone LED tube lights has a shatterproof coated glass tube and a frosted lens that eliminates pixelation. There is no risk of broken glass - making them ideal for food service (in fact, they are ETL Sanitation Listed NSF/ANSI Standard 2 - Food Equipment) applications. Keystones Smart Drive LED T5 tubes eliminate the need to remove or bi-pass your existing ballast. This plug-n-play direct replacement for F54T5HO fluorescent tubes is compatible with most program start electronic ballasts and requires no rewiring during installation. Lamps were tested for compatibility with the program start ballasts shown in the compatibility chart. Ballasts that do not appear on the chart might still be compatible but have not been tested. All testing has been performed with a stable main supply. The quality of the local main, existing installation and wiring, as well as different manufacturer versions of the above ballasts may affect lamp performance. Since no assurance can be provided regarding these factors, it is a general recommendation to perform a test on-site prior to installing the LED lamps.
