  1. Im L ovin' It {them}! 5 Star Review

    Posted by on 22nd Sep 2017

    Bought a new to me {used) Fleetwood Bounder and just finished switching out all of the interior bulbs and headlights to LED. Steve answered various installation questions from me promptly and live over the phone too. Two things really stand out from the process.
    1. The speed at which the orders come is truly remarkable. It seems like they are driving them over from across town. Granted I only live a state away but they are seriously fast at processing.
    2. They have warm white tube bulbs. I hated the inherited cool whites, it felt like I was eating dinner in my doctor's office. Tried natural whites in some of the other lights and they were marginally better, good for reading maps etc. but still not the ambience I was looking for. Warm white is so nice. Thanks M4!!

  2. An essential mod for your RV 5 Star Review

    Posted by on 12th Sep 2017

    These lights are just fantastic, the light is warm and even, the retrofit is not too difficult if you can follow the instructions. We removed the old ballasts to save the weight and room under the ballast cover, that will take a punch and drill if they are riveted in place.

  3. Energy Savings 5 Star Review

    Posted by on 5th Sep 2017

    Great step forward when you swap out your florescent tube for an LEDs set in a round tube. I was impressed with clarity of instructions for re-wiring a florescent fixture, and by the packaging of these tubes by M4. Great job and prompt shipment!

  4. 18" T8 3200K 5 Star Review

    Posted by on 1st May 2017

    Got to tell you if you want the best and quality then you have to pay up! Quality A++. Perfect lighting. Yes, they are pricey, but I am confident that these will be the last time I have to buy these.

  5. 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!

  6. 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.

  7. 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!

  8. 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.

  9. 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.

    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.
