  1. Easy conversation 5 Star Review

    I converted one light fixture in my RV to the LED tubes. They are pretty easy to install and give great light. Less expensive than a new fluorescent fixture.

  2. Easy install 5 Star Review

    I found the M4 Youtube video closely mirrored the provided instructions and made the whole install/conversion a VERY easy process.

    M4 Note: Just a quick note, the video you found is probably made by TheRVGeeks and featured M4 tubes. Great to hear it helped though!

  3. Love them 5 Star Review

    I had installed these bulbs in a couple of fixtures about a year ago and love them so much I purchased the bulbs for the other lights in my RV. They are fairly easy to install and give great light.

  4. Very Happy With Results 5 Star Review

    Posted by on 16th Apr 2018

    Installed 18" LED tube lights in my RV replacing the Florescent Tubes. Of course fixtures in mine were the riveted type so had to do a little more work to install along with buying a rivet tool to put back together the way I wanted. I ordered more LED tube lights to do 2 more fixtures today as the first one came out great.

  5. Great product, easy conversion 5 Star Review

    Posted by on 2nd Apr 2018

    Steve was great to work with. I had lot's of questions about different bulbs. He pointed me in the right direction for each style I had. These florescent bulbs were an easy conversion with the wiring instructions that came with the bulbs. When I decided to replace all my bulbs with LED's (10 florescent, 15 wedge style 921, a couple 1141 and couple of 1383) I only wanted to do it once. I wanted everything to match in color. I choose M4 because they offered a great bulb for each type I had and at a great price. I've only had them in a week, but the light output is superior to what I had. They also use less energy. I looked at a lot of other bulbs, and these are the best and at a lower cost. If I need bulbs for another installation, I will buy again from M4.

  6. Easy conversion 5 Star Review

    Well another RV florescent ballast bit the dust, as each one dies I order another LED replacement kit from you. Instructions are great and installation a breeze. I almost look forward to having my old bulbs and ballast die just so I can have the superior light quality of the LED. Thanks again for having such a great product available.

  7. Another great product from M4 5 Star Review

    Posted by on 2nd Mar 2018

    Great bulbs, we chose the "Cool White" on M4's recommendation. They are very bright and are exactly what we wanted.

    You should be aware that there is minor rewiring of the fixture required. M4 sends a detailed installation sheet with the bulbs. I highly recommend changing your existing bulbs to LED.

  8. Great lights 5 Star Review

    Posted by on 2nd Mar 2018

    These were very easy to install in my existing fixtures, rewiring for LED was easy. Great color. Will buy more.

  9. Good replacement 5 Star Review

    Posted by on 7th Feb 2018

    Our camper's fluorescent fixture died. While these lights are rather expensive, they are less costly than a new fixture. The light they produce is the same color and maybe even a bit brighter than the fluorescents they replaced. It was easy to modify the old fixture to work with these new lights.

  10. great 5 Star Review
