The Speclite 4-foot T8 tube is designed with an aluminum extrusion to maximize heat dissipation and a polycarbonate lens to extend its lifespan. This T8 tube effectively replaces your traditional T8 and T12 fluorescent tubes with G13 pins.

This model offers five selectable CCT color temperatures and adjustable wattage on a single tube, and is compatible with 120-347V power, meeting all your lighting needs. What sets the Speclite tube apart is its unique installation flexibility: it can be installed with or without a ballast, connected at both ends or just one, making it a truly universal installation solution. Perfect for upgrading your commercial or industrial lighting systems, this LED tube not only reduces operating and maintenance costs but also improves energy efficiency and lighting quality.
