Sign lighting that's built to impress.

Replace outdated fluorescents with LED.

Sign Tubes

Linear Tubes

RAB's double-ended sign tubes are ideal replacements for traditional T12HO and T8HO fluorescent tubes used in sign applications. They fit in all existing sign fixture sockets...simply bypass the ballast and you're good to go!

Big or small, we’ve got it.

Retrofit sign tubes come in various lengths, from 1.5ft up to 10ft. All models come in a color temperature of 6500K in order to deliver the optimal, bright, daylight color that's preferred for sign installations.

Fix it and forget it.

Double-ended, ballast bypass installation ensures that you won't need to worry about spending the time and money to replace a failing ballast. Rotatable R17d endcaps also allow the installer to direct light where it's needed.

Built to perform and impress.

All sign replacement tubes are made of robust plastic and aluminum, with LEDs on both sides that provide 360° omnidirectional light output. The optics are specifically designed to diffuse light and deliver smooth, even distribution while eliminating harsh hot spots.

We know how to accessorize.

Two accessory kits are available that include cables with magnetic hooks to support the installation of tubes that are 8+ feet long, helping to prevent any annoying sagging within the sign.
