Sylvania Octron 800 Ecologic T8 Fluorescent Lamp

The Sylvania Octron® 800 Ecologic® series is a family of T8 fluorescent lamps engineered for reliable general-purpose lighting in commercial and industrial spaces, available in multiple model configurations to match different fixture and lumen-output requirements. Every lamp in this series shares a 2-Pin Medium Bi Pin base for secure, standardized fixture connection and a T8 bulb type for direct compatibility with standard T8 fixtures and troffers. Depending on the specific model selected, wattage, length, lumen output, color temperature, and CRI can vary, allowing facility managers and electrical contractors to select the configuration that best fits their fixture and lighting design needs. Representative specifications within this series include wattages such as 25W, color temperatures such as 3500K, an 82 CRI rating for accurate color rendering, and an average rated life of 30,000 hours.
