  1. Great replacement, love the color! 5 Star Review

    Posted by on 22nd Mar 2017

    I installed 4 tubes in the existing fixtures of my 2006 Tiffin Phaeton and all worked perfectly. The instructions were easy to follow and they fit perfectly. The only difficulty was the fixtures in the Phaeton were riveted closed, so the rivets had to be drilled out, but that's certainly not the fault of the bulbs! :) The bulbs have a nice 'cozy' feeling just like incandescent bulbs and there's no more flicker! Thank you for such a great product!

  2. Will be purchasing more LED's 5 Star Review

    Posted by on 30th Jan 2017

    I'm just now starting the process of changing out all our lights and there are many...This first set of lights work very well, and the easy to follow instructions for altering the fixture made for a quick reto-fit.

  3. Great replacement option for the overhead florescent T-8 bulbs! 5 Star Review

    Posted by on 10th Oct 2016

    We have been slowly replacing the original bulbs with LEDs in our motorhome. When both florescent T-8 bulbs in an overhead fixture died at once it was a perfect opportunity to switch to LED. So glad we did! The LED replacement bulbs were relatively easy to install – about a 20-minute project. The bulbs look great – they are actual tubes not just strips of LEDs so they look/function the same as the original bulbs (important if you are converting over time and not all at once). We chose the “warm” white (3200K) which is nearly indistinguishable from the 3000K fluorescent bulbs we replaced. We will definitely be getting more of these! Great quality product and a gem of a company. We really appreciated the great communication and super fast shipping – essential when you are traveling and have a limited window to receive packages. Thanks!

  4. Work great just like the other 3 pairs we bought 5 Star Review

    Posted by on 18th Jul 2016

    This is our 4th pair of these LED lights. We have been replacing the traditional lights in our RV as they burn out. All of the lights we have bought from M4Products over the past year are still working great.

  5. Real "Warm" white LED 5 Star Review

    Posted by on 4th May 2016

    I ordered 8 of these to test and they are great. I tried other brands before that claim to be warm white but in reality they were cold white.

  6. Did what is advertised 5 Star Review

    Posted by on 9th Sep 2015

    Easy to install especially after watching the referenced video. They perform wonderfully and exceeded my expectations. This is a really great product.

  7. warmer light and brighter than flourescent tubes! 5 Star Review

    Posted by on 12th May 2015

    I am very happy that I chose the M4 Products tube lights, they are far superior to the versions available at the RV centers. This is my second time using M4 and again they have scored high on my "will use again" meter. We chose the warm white tubes because my wife does not like the "blue" tint from high Kelvin lighting. I was pleasantly surprised by the amount of light I got from the new tubes. They filled the room with a bright, warm light, and I saw a significant drop in the amount of charging my batteries receive. The tubes were easy to install, about five minutes per fixture, and M4 sent all the required wire nuts and extra wire. The only complaint I have is waiting for the lights I want to be in stock. I highly recommend M4 Products, they are the best around. Thanks.

  8. Just what I was looking for! 5 Star Review

    Posted by on 31st Mar 2015

    The overhead 18" tube fluorescent lights in my 40' Itasca DP always bothered me. I just hate fluorescent lights. I had replaced most of my incandescent light bulbs in my home with warm LEDs and have been super happy. I'm sold on LEDs, so I was about to try LED strip lights in my RV when I discovered M4Products on YouTube.

    These lights are super easy to install if you can do basic wiring and they fit perfectly.

    I'm super happy with the result and with the customer service. I original ordered the cooler 4500k natural white bulbs but I wanted something closer to a light bulb in warmth. The 3200k lights are exactly what I wanted and M4 happily exchanged all 8 of the 4500k lights for me.
