The Replacement for GE F40WW/RS/WM/34 T12 Fluorescent Tube is a durable lighting solution for warm, inviting spaces. This 40-watt T12 tube, with a 1.5-inch diameter and medium bi-pin G13 base, delivers approximately 3,200 lumens of warm white light at 3000K-3500K. With a 20,000-hour lifespan, it provided reliable illumination for offices, retail spaces, classrooms, or garages before being phased out for modern upgrades. Originally designed for environments needing a cozy atmosphere, this tube offered bright, even light to enhance comfort and productivity. Its 1.5-inch diameter fit standard T12 fixtures, operating at 120 volts for consistent performance. However, it’s now replaced by more energy-efficient options like the GE F40CW/SS/ECO, Philips F40WW/SS, or Sylvania F40WW/SS, often T8 or upgraded T12 tubes, for better savings and longevity. This replacement ensures compatibility with G13-based systems, offering modern upgrades for similar applications. Built for reliability, it’s a historical reference for lighting, but its successors provide enhanced efficiency.
