About

F40T12 4-Foot Fluorescent Tube: Legacy Natural Daylight Lighting 

The 40-Watt F40T12 fluorescent tube is a legacy lighting solution that has been widely used in offices, garages, workshops, warehouses, and commercial spaces for decades. Producing 2,600 lumens at 5000 Kelvin Natural Daylight, this tube provides crisp, bright illumination that mimics midday sunlight, reducing eye strain and enhancing contrast for detailed tasks. 

However, T12 fluorescent technology is outdated, and LED retrofits now offer a better alternative—eliminating ballasts, cutting energy costs, and delivering superior light quality. 

F40T12 Fluorescent Engineered for Longevity & Performance 

✔ 90 CRI for Superior Color Accuracy – See true-to-life colors with enhanced clarity. 

✔ Cathode Guard Technology – Prevents end blackening, ensuring consistent brightness over time. 

✔ Extended-Life Phosphors – Keeps the bulb brighter for longer throughout its lifespan. 

✔ Eco-Friendly Mercury Capsule – Uses 70% less mercury, reducing environmental impact.
