  • LED Replacement fluorescent T8 tube F15T8
  • Replacement LED Tubes F15T8 T8


Our new 102-LED F15T8 12VDC/24VDC replacement. Super-bright, super-efficient LED tubes. 

This bulb replaces the common 18" (451mm) T8 style bulbs used in 12V and 24V DC fixtures in boats, campers, and RVs. 

NOTE: This LED tube is for 12VDC or 24VDC applications.

*For use in any 120/220V AC application, simply replace your ballast with one of our AC-DC LED Drivers.



It utilizes the newest surface mount 3528 LEDs, in a natural white color that looks just like the original fluorescent, but is brighter, lasts 10 times longer, and draws less than half of the current.

See recent customer reviews here.

These bulbs feature the Marinebeam Constant-Current chipset, so these will work in both 12VDC and 24VDC fixtures. With 102 high-output SMD LEDs, a unique Alumicore substrate, and a high-surface-area aluminum spine, the technologies converge to give you a drop-in product, that is guaranteed to perform and satisfy in your F15T8 fixture. A perfect replacement for Thin-Lite T8 tubes, or for off grid fluorescents using 12V or 24V DC power.

Output Color: Natural White (Fluorescent White) 6150°k color temp. or Warm White 3,000°k color temp. The Natural White is designed to look exactly like a natural color fluorescent and is brighter than the Warm White. The Warm White has better color rendering, and is similar to a warm compact fluorescent color.

If your fluorescent 12V or 24V ballast needs replacing, now is the time to upgrade to LED at about the same cost as a new ballast. No ballast required!

  • Voltage: 10-30VDC
  • Wattage: 6W
  • Amperage (12V): ~0.5 Amp
  • Luminous Flux: 630 Lm (NW)/ 375 Lm (WW)
  • Beam Angle: 120°
  • Dimensions: 17.75" (451mm) x 32mm
  • Replaces: 18" F15T8 fluorescent tubes
  • Warranty: 2 years 

This LED tube allows you to rotate the pin orientation 90 degrees if needed for Thin-Lite Model 115 and other fixtures where the bulb contacts are mounted sideways. This is easily accomplished with a small jeweler-size Phillips screw driver, or we can pre-configure them for you, just note that you need the 90 degree pin orientation in the comment section at checkout.

NOTE: These LED bulbs have our built-in constant-current driver already installed, but they do not require the high-voltage ballast that is in your current fluorescent fixture. While the bulbs drop right into your fixture, your existing fixture will require a slight modification, which involves bypassing the fixture's existing ballast. It is a simple modification requiring nothing more than a wire-cutter and some butt-connectors. Find conversion instructions here

For twin tube fixtures, reference the video HERE. If you don't wish to modify your existing fixture, or if your existing fixture is old and crummy looking, we offer several styles of economical fixtures pre-configured for use with our tubes.
