Our customers kept asking us to develop a solution for upgrading their existing fluorescent fixtures. We responded with the world's first F13T5 21" LED tube to easily convert your existing 12VDC or 24VDC fluorescent fixture to LED technology.

These LED tubes easily convert Aqua-Signal, Thin-Lite, Beneteau, Catalina, RV, and motorhome fluorescent fixtures using 21" T5 tubes.

These tubes are NOT for 120VAC home use.

Our LED replacement tubes provide a much more direct light, with output and color that matches your existing fluorescent. Of course, it does this at 1/3 the power, without the flicker, hum, and without any UV emissions.  See customer reviews here.  The tubes feature our proprietary internal Constant-Current circuit, which means that you will get the highest output, longest life, and worry-free performance. 

These tubes feature 120 high-efficacy surface-mount 3528 format LEDs bonded to an engineered thermal-substrate, which conducts and dissipates heat directly to a high-surface-area fluted aluminum thermal heat-sink structure enveloping the emitter board. This, along with our non-resistive and highly-efficient converter-driver allows us to drive the LEDs at maximum power in the same form-factor as your original tube.

Output Color: (Fluorescent White) 6150°K Natural White - designed to look exactly like a natural cool color fluorescent.

  • Voltage: 10-30VDC
  • Wattage: 6W
  • Amperage (12V): 0.5 Amp
  • Luminous Flux: 655 Lumens (NW)
  • Beam Angle: 120°
  • Dimensions: 531mm (21")
  • Replaces: 21" F13T5 fluorescent tubes (G5 base)
  • Warranty: 2 years

NOTE: These LED bulbs have our built-in constant-current driver already installed, but they do not operate with 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. Click HERE for instruction sheet.  For a twin tube fixture, reference the video HERE.

    Great replacement for a fluorescent

    We have fluorescent fixtures in our closets, and moving to the LED lights has improved the lighting in the closet while decreasing cost.

    Would have given it a 5 but...

    I'm generally pleased with the product with one exception. For some reason, the pins on one end of each lamp are dimpled. The process caused the pins to be bent on several lamps, some of them at almost 90 degree angles. I had to straighten those pins with pliers which may have weakened them. None have broken so far. I recommend that the manufacturer pay more attention to quality control.
