Beyond LED Technology’s SIGN STORM 30″ double-sided LED sign tube is engineered for large double-faced sign cabinets, pylon signs, blade signs, and other oversized signage that requires bright, uniform illumination on both sides. Its extended 30″ length reduces the number of tubes needed per cabinet, simplifying installation, wiring, and long-term maintenance. The Type B double-ended ballast bypass design installs directly into existing tombstone lamp holders, making retrofit projects fast and efficient without socket replacement. Individual optical lenses over each LED chip provide smooth, consistent 360° illumination across both sign faces, minimizing visible hot spots and delivering a clean, professional appearance from every viewing direction.
