  1. Great customer service 5 Star Review

    Posted by on 3rd Nov 2017

    Ordered 2 bulbs to try them out I am no electrician but after reading the detailed instructions and watching the video I must say it was pretty simple. Wow what a difference in light,decided to do the rest of the overhead lights ordered them right away I am on the east coast and they are on the west coast I had only one week before a 5 week trip I stated that on my order. I got a call from M-4 telling me no worries they will be there.And indeed they were installed the other 8 bulbs and presto we have great lighting.
    I highly recommend M-4 products as they know RV lighting.

  2. Great Lights 5 Star Review

    I replaced two double tube florescent lights in our 5th wheel with the easy to follow instructions provided with the bulbs and my wife was really impressed at the difference in the light provided by the new bulbs.

  3. Great replacement for flourescent. 5 Star Review

    Posted by on 10th Sep 2017

    The bulb is great. The website gives instructions for removing the ballast from a double bulb fixture, for those of us with no imagination it would be nice to also include instructions for installation in a single bulb fixture.

    Excellent product. Easy to follow instructions. Easy to install.

  6. F15T8 LED Replacement 5 Star Review

    Posted by on 15th Jul 2017

    Product as described, easy to install. I purchased these LED replacements because the 960 Lumens exceeded that of a F15T5 fluorescent tube at 825. Most replacement do not. Also I wanted 6000 Kelvin or greater. These were installed in my motorhome.

  7. replaced all my interior motorhome lights very happy 5 Star Review

    I think I will like them very much .

  8. Best thing since sliced bread... 5 Star Review

    Posted by on 7th Jun 2017

    I've just replace the next three (3) in a series of 12 fixtures and amazed at the difference in the amount of light I now have in my RV. When I have friends over they even comment about the new lights. One of the best things is I've got the rewiring of the fixtures down to under ten (10) minutes. With only four (4) fixtures to go I wonder what I'll do next??

  9. Cool White LED 5 Star Review

    Posted by on 20th May 2017

    I am so pleased with the lights I have installed so far that I ordered more. I was going to replace them a few at a time, but they made such a difference I decided to "bite the bullet" and do all of them. Glad I did. I am looking forward to boondocking more this summer and these will help me not use up my battery.

    Instructions are very clear and easy to follow. Customer service is outstanding! I wasn't paying attention and ordered the wrong bulb. Very easy to exchange!

    The CW LED lights are so bright and we can actually see in our bedroom now with just one fixture replaced. We hope to replace them all as we are able. Thanks to M4 Products for excellent customer service!
