  1. Best Interior Upgrade You Can Make 5 Star Review

    Posted by on 19th Apr 2018

    The old fluorescent bulbs and ballasts were worn out. Checked out the options for LED replacement and found many options. Quality, price, and ease of installation was hard to determine until I found m4 products. I was SOLD. Received the product in only a few days. The instructions and ease of installation were easy for anyone with basic knowledge of electricity. Replaced 6 double bulb fixtures in less than a day. The best part is my better half is now a happy camper and the power draw on our electrical system has been substantially reduced. Plan on changing out all the other light fixture bulbs with the M4 Products. Read the reviews and you will see why. Thank you M4.

  2. Excellent Product 5 Star Review

    Posted by on 17th Apr 2018

    I recently bought an older motorhome and replaced all the 18 inch interior tube lights from fluorescent to LEDs. The 18 inch LED replacement tube lights were very easy to install, with minor wiring modifications. I watched the video which made it exceptionally easy. LED offers better lighting, cuts on immediately and use less power. A real good RV upgrade.

  3. Excellent Improvement! 5 Star Review

    Posted by on 11th Apr 2018

    Replace all the overhead lights in my motorhome with these and am very impressed. Excellent brightness and it was simple to install them. I did have some questions on my installation and I called Steve. What i really like about his business is they answer the phone every time. No buttons to push, no waiting, no elevator music. He answered my questions and I finished with my installation with zero problems. I would highly recommend Steve and his company for any LED or lighting purchases.

  5. Easy transition to LEDs. 5 Star Review

    Posted by on 30th Mar 2018

    Replaced the flourescent tubes in the motorhome bathroom. No more heat bearing down, brighter lighting, and less stress on the battery system. Took about ten minutes to wire and install after watching the online video.

    The easiest conversion I have ever experienced. The detailed instructions were easy to understand and follow. I recommend these lights to every RV owner.

  8. Excellent Product and Excellent Customer Service 5 Star Review

    Posted by on 22nd Feb 2018

    As always though a bit more expensive than other suppliers the excellent customer service and the quality of the product brings me back time and time again.

    M4 Notes: You will find our tubes to be $8.00-$10.00 less per tube than any other Reputable Brand, but we offer a better tube with better components. If you see something cheaper, there is a reason why... Thank you for the support.

  9. Fantastic LED lamp to replace old fluorescent tubes in RV. 5 Star Review

    Posted by on 10th Feb 2018

    As advertised. Quick and easy installation. Outstanding light quality. The only drawback is that it produces some rfi that puts a buzz in my FM radio.

  10. Excellent Product and Excellent Customer Service 5 Star Review

    Posted by on 8th Feb 2018

    Someone recommended another company to me for the LED lights I needed. One phone call to this company where I was connected to someone who had no knowledge about their products, their spec's, etc. convinced me to go back to M4 where I knew I could talk to a knowledgeable individual and where I knew I would get an excellent product. And indeed I did. I talked directly to Steve who took the time to verify the product was in stock. The 18" fluorescent bulbs were promptly shipped and arrived when expected. They are of the highest quality and were very easy to install. The difference inside our coach is as they say "the difference between night and day". The lights provide a nice bright white light and the icing on the cake is that they are energy efficient. I will never again even think of going anywhere else but to M4 for LED products.
