  1. Great LED replacement light 5 Star Review

    Posted by on 6th Jan 2018

    Lots to say so let’s get to it.

    1. Extremely quick shipping and packaged better than 99% of the packages I receive.
    2. I don’t need the rewiring instructions because of my electrical background, but very well-done intructions!
    3. Rotating end-caps that I did not expect. That’s great.
    4. I read a review that said they only used (1) bulb per fixture because they are so bright. I ordered (2) bulbs just to try them out. Yup, they are bright enough to only need (1) per double-bulb fixture.
    5. Very sturdy and high-quality construction.
    6. Pricey for my budget, but well worth it in the end for the level of quality.

    Overall I am very happy I spent the extra money on these lights.

  2. Very simple installation 5 Star Review

    Posted by on 5th Jan 2018

    I just did our 12" kitchen fixture with M4M bulbs and was very happy. I then ordered the 18" bulbs for the larger fixture and it was even easier to install because the bulb and driver and all in one. I'm not telling my wife to see if she notices the difference in light next week when we leave, but I'm sure she will. On the first fixture I had to call Steve for a clarification as only one bulb lit up: I emailed a pic of my bulb installation and he called right back to tell me what I needed to do(a simple fix). Very impressed with their service. I have the majority of the 12V lights in our motorhome changed to LED and exclusively M4M products.

  4. Great improvement... 5 Star Review

    Posted by on 19th Dec 2017

    Real happy with the results, fast shipping, super easy insulation. Thanks Steve

  5. Easy replacement 5 Star Review

    Posted by on 9th Dec 2017

    Finally, replaced the fluorescent lights. The installation was easy using the video posted by RVgeeks. Took longer to get the old ballast removed than it did to make the wiring changes. Love the lights and the fact that I am reducing the load on the batteries. M4 products are well made quality lights.

  6. Beautiful light 5 Star Review

    Posted by on 7th Dec 2017

    These tubes are really bright and have a great color that blends well with the old fluorescent tubes. They are so bright that I only need one instead of two in a fixture. This is like getting two for one. A pleasant surprise.

  7. This kit is excellent! 5 Star Review

    Posted by on 4th Dec 2017

    Super easy to do, watch the RV Geeks video and follow the written directions. I have zero electrical expertise and I did this in about 10 minutes. Super bright, great addition to our camper. Highly recommended.

  8. More light and no heat! A great upgrade to my RV 5 Star Review

    Posted by on 4th Dec 2017

    High quality replacement ! In addition to reading the supplied instructions, I recommend going to the M4Products.com site and following their detailed instructions with step by step photos. My 1999 Winnebago is now incandescent & floresent free, more efficient and most importantly much cooler inside thanks to M4Products.com! ⭐️⭐️⭐️⭐️⭐️

  9. Such an awesome upgrade! 5 Star Review

    Posted by on 29th Nov 2017

    I've had them in the RV for a year and they are awesome!

  10. Great lighting and instructions! 5 Star Review

    Posted by on 7th Nov 2017

    We love these bulbs and the energy reduction we will have in the future! Changing the wiring was easy with the detailed instructions M4 provided AND the GREAT videos on YouTube by RVGEEKS

    Even better than these bulbs is the customer service of M4! So helpful in assisting us in determining the correct bulbs and type to replace all of our bulbs with LED. THANK YOU M4!
