    18" T8 12v Tube Light Replacement. Standard Size T8 Tube, Actual Size 17 1/4" excluding pins.

    • Non Polarity, one end of the bulb gets power, the other side gets ground.  Installs either direction.
    • Basic rewiring of the fixture is needed to eliminate the florescent tube ballast

      LOVE these lights...Replaced 10 Fluorescent bluish white with new LED warms. SO much nicer and very pleasant. Wiring was a breeze, instructions well done. Very happy and have a few more to replace soon. Thanks Steve M4

      See above review of subject. LOVE the lights, a world of difference in the ambiance to get rid of bluish tubes.

      retrofit tubes

      Posted by James Cooper on 16th Mar 2021

      Wiring was easy, had to modify fixture so one tube would fit the socket. Dremmel and wheel and works great. M4 Note: James, would love to learn or see more on what needed modification on your fixtures, this is not the norm; always looking to add to the knowledge base.

      Excellent LED retrofit tubes

      Posted by Julie Spurbeck on 2nd Nov 2020

      If you want your light upgrades to go smoothly, turn to the M4 retrofit tubes. This is my second purchase. The first upgrade went so smoothly, I finished my rig! Don't waste your time with the Amazon tubes.

      Second retrofit with this light was a success!

      Posted by Julie Spurbeck on 26th Oct 2020

      I attempted to LED my RV lights several years ago and gave up. Being stuck at home w/ COVID, I decided to give it another shot. I spent the extra $$ on the M4 18" tubes, and I am so glad that I did! They came on with the switch as expected!! All of this time I thought I messed up the re-wiring and it was just the cheap Amazon LED retrofit tubes! Wish I'd have known about M4 a few years ago....
