Reimagined Fluorescent Brilliance

Experience the next generation of signage illumination with the Superior Life® 48-inch High Output T8 LED Sign Tube. Designed to replace traditional fluorescent T8HO lamps, this 18-watt LED delivers a bright 6500K daylight color temperature with exceptional clarity and color accuracy. The crystal-clear finish and 330° beam angle ensure even light distribution across large sign faces, showcasing vibrant graphics and text with stunning precision.

Power and Versatility

Engineered for versatility, the LED SIGN 48in 18W T8/65K/CL/2500LM/HO operates seamlessly on 120–277 volts, accommodating both commercial and industrial signage applications. With an impressive 2500 lumens of output while consuming only 18 watts, this LED achieves 139 lumens per watt efficiency, making it a superior energy-saving replacement for legacy fluorescent systems.

Built for performance, it features a RDC (R17D) base, ensuring secure mounting in sign housings and effortless retrofitting. Rated for damp locations (IP20), this LED tube withstands demanding environments while maintaining stable, flicker-free illumination.

For the Love of Color

With a Color Rendering Index (CRI) of 83, this LED sign tube brings out the vivid details of your branding and design elements. From commercial storefronts to roadside billboards, the 6500K daylight spectrum provides a crisp, high-definition glow that enhances visibility and readability — day or night.

Rugged Design, Superior Durability

The Superior Life® LED Sign Tube is built with robust components designed for extended performance. The high-output design and clear polycarbonate housing ensure maximum lumen retention over the lamp’s 50,000-hour lifetime. Its durable internal driver and solid-state construction resist vibration, temperature variation, and impact — making it ideal for both indoor and outdoor sign cabinets.

Operating reliably between -4°F and 104°F, this LED maintains consistent brightness even in extreme climates.

Effortless Retrofit and Installation

Engineered for efficiency, the LED T8/HO tube offers a simple retrofit solution compatible with existing RDC (R17D) sockets. It eliminates ballast dependency, reducing maintenance and operating costs while ensuring long-term reliability. Its clear finish and wide beam angle evenly illuminate the entire sign face for professional-grade presentation.
