  1. Loose the ballast. 5 Star Review

    Posted by on 14th May 2019

    We are changing all of our fluorescence bulbs in our large motorhome now that I have found these. There will be a total of 32- 18" bulbs. The quality and features of these L.E.D.s makes me feel secure of a good investment. We are using warm and neutral colors.
    The rvgeeks5 code helps. We are over half way in replacing our lights. Once you see how easy the wiring is changing becomes fun. I remove the ballasts so wiring stuff easier. Happy!

  2. T-8 conversion is so simple a caveman could do it 5 Star Review

    Posted by on 15th Apr 2019

    I recently purchased 10 of these bulbs to convert my Motorhome to LED lighting. The instruction's were clear and concise and the actual conversion took maybe 10 minutes on the first fixture and 5 minutes on the remaining four. The bulb's are bright but not blinding and the room lighting is warmer now. I'm extremely pleased with M4's.

  3. easiest install ever and super bright Leds 5 Star Review

    Posted by on 6th Apr 2019

    I recently installed 10 of these in my Coach and it was fast and easy with well made instructions ,also check out the video on YouTube which should be viewed if you have any doubt. This is not my first purchase from M4 and it won't be my last either. Great to deal with and fast shippers too!

  4. easy to install as advertised 5 Star Review

    The light was easy to install and gives out natural light that is easy on the eyes, this one light replaced two florecent bulbs.

  5. 18" T8 12v Tube Light 4500K 5 Star Review

    Posted by on 15th Feb 2019

    This is my second order of this product. Like the results of my first order for my vanity area so much, I order 10 more lights to upgrade all the rest of the center lights in my 2005 Camelot. When I was replacing the old fluorescent lights, found one of the lens covers had been heated enough from a failing fluorescent light to cause the start of a melt spot. The quality of products continues to be great. Perfect color rendering to the other LED tubes I put in from M4. Now, great lighting in the coach, great color and they all match. Could not bee happier.

  6. 18" T8 12v Tube Light 4500K 5 Star Review

    Posted by on 4th Feb 2019

    Purchased 6 of these to upgrade the lights in the "bathroom" area of my 2005 Camelot. Wow, what a difference, lots of light. The color is very close to the fluorescent tubes they replaced and match the 36" tubes I just upgraded with LED tubes in the kitchen area. They arrived quickly, instructions were easy to follow, installation was easy and took little time to complete. I liked them so much, just ordered 10 more to replace the rest of the lights down the center of the coach. Can't beat the aluminum heat sink the LED's are mounted on and the rotating end pins. As usual, can't beat the quality of the product and the product of the company. Steve is quick to help, a wealth of information and responds quickly.

  7. Great Product and Customer Service 5 Star Review

    Posted by on 13th Jan 2019

    I bought 10 of the T8 LED tubes to replace the florescent ceiling lights in my RV. I tried both the NW and CW and like both for different reasons. What separates M4 LEDs from other brands is their attention to detail in the design. The LEDs in these tubes are mounted on an aluminum heatsink which helps dissipate the heat they generate and allows them to run cooler and last longer. They also have rotating end caps which allow you to align the LED strips at their preferred orientation. I am very happy with the LED tubes I purchased from M4LED. And Steve was very helpful with explaining the different options. I will definitely buy more LEDs from M4LED.

  8. Amazing amount of light 5 Star Review

    Posted by on 3rd Jan 2019

    Bought these for my single battery truck camper. Was wanting to reduce power demands and converted everything to LED. I used these in the fixture above the dining table. They put out way more light than the fluorescent tubes, and the 5050 tape strips they replaced. Highly recommended.

  9. Excellent product with exceptional service 5 Star Review

    Posted by on 2nd Jan 2019

    I have a vintage 1985 AlpineLite 5th wheel. Just starting to restore & convert the lighting to LED. I called M4 after seeing a YouTube from RV Geeks on their LED conversion. I spoke with Steve the owner of M4 & he asked what was the end result I was looking for. What a great question! So I ordered the Natural White, which is still a bit on the bright side, but you can turn the tube ends to diffuse the light & get exactly the brightness you would like. At times you want it to be brighter, like if you dropped a small object & need to get on your hands & knees to find it. Other times you may want it a little less bright. Great product because you can control these, unlike other products on the market. I highly recommend these.

  10. Quality product 5 Star Review

    Posted by on 27th Dec 2018

    Great product and very well made. Simple installation and no more trips to Home Depot for fluorescent bulbs.
    Have switched to LED in 3 fixtures so far, 5 more to go.
