  1. 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! ⭐️⭐️⭐️⭐️⭐️

  2. 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!

  3. 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!

  4. Exactly as promised 5 Star Review

    Posted by on 31st Oct 2017

    Great product and Great company who handled an error I made. They resent the correct product with efficiency and courtesy. Instruction and videos were all I needed. Converted my Motor Home and I am so satisfied I will convert my fifth wheel next spring.

  5. Exactly as promised - Easier than expected to install 5 Star Review

    Posted by on 18th Oct 2017

    I first order one pair to replace my halogen lights. The RV Geeks installation video exactly matched my wiring set up and made me really comfortable completing the install myself. It took 10 minutes with the video to complete and worked like a charm. Everything I needed and more were included in the package. The LEDs fit perfectly, are brighter than the original halogens, and I can already see the impact to energy usage when looking at baseline usage + lights. I ordered 2 more sets and have completed half of my RV. Next month, I will finish the conversion of the halogen lights and start working on the rest of the fixtures - of course using m4 to do it all!

  6. Why did I wait so long? 5 Star Review

    Posted by on 3rd Oct 2017

    Simple to replace, especially with the help of the RV Geeks video. Can’t say enough about the owner Steve - superb customer service...thanks, Steve!

  7. Survived IRMA 5 Star Review

    Posted by on 26th Sep 2017

    I started my conversion to LED with the smaller bulbs then moved on to replace the tubes. The T8-120-3528-18 replacements were very easy to install, completed just a couple of days before leaving on vacation. They performed very well during the trip which became extended by 7 days as Hurricane IRMA came directly over our home so we stayed North. Very easy to install, fantastic light and saved our batteries while we dry camped.

  8. Fantastic replacement 5 Star Review

    Posted by on 13th Sep 2017

    Our experience with switching over to LED on all the different types of lights found in our coach has been very mixed. Not any more, these m4 natural LED lights for all of our 18" fluorescent fixtures are wonderful! Very good light and easy to do the switch over. We will be buying more to continue the change over.

  9. Clean install 5 Star Review

    Posted by on 25th Aug 2017

    I bought enough bulbs to replace 3 failed ballasts. The install videos on youtube made the conversion of the fixture pretty simple and I like how they mimic the other florescents in my coach. I initially ordered the cool white as that is what my existing bulbs are, but they were too cool, so I swapped them for the natural white. Much closer in color. While there are cheaper solutions using led strips, this is a very elegant solution which I prefer.
    Customer service was great! Order shipped quickly, and my swapping for different color bulbs was painless and quick.

  10. Delivers on promise. 5 Star Review

    Posted by on 4th Aug 2017

    Followed the RVGeeks video to rewire the fluorescent fixture. Nice & easy to follow. New LED bulbs worked immediately and look great.
